The following is a specific example to illustrate the implementation of the "treadmill and its track control method" disclosed in the present invention. Those skilled in the art can understand the advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various modifications and changes can be made to the details in this specification based on different viewpoints and applications without departing from the concept of the present invention. In addition, the drawings of the present invention are only for simple illustration, and are not described in advance according to the actual size. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the technical implementation of the present invention.

It should be understood that although the terms first, second, third, etc. may be used herein to describe various components or signals etc., these components or signals should not be limited by these terms. These terms are used to distinguish one component from another component, or one signal from another signal. In addition, as used herein, the term "or" may include any one or all combinations of more of the associated listed items depending on the actual situation.

The invention uses an image sensor to detect specific light images or user's image features to automatically control the running speed of the treadmill.

First, refer to FIG. 1A , which is a schematic diagram of a treadmill provided by an embodiment of the present invention. An embodiment of the present invention provides a treadmill M, which includes a running track 20 , a first signal providing component, a first sensor 51 and a controller 30 . The first signal providing component is disposed on the first side 204 of the runway 20 . The controller 30 is coupled to the first sensor 51 . In detail, the treadmill M also has a support body 10 and a control panel 103 installed on the support body 10 . The controller 30 is disposed in the control panel 103 . The control panel 103 provides relevant information such as the user's running speed, time and warnings, and can directly adjust the track through the information. The support body 10 has a first support rod 101 and a second support rod 102 disposed on two opposite sides of a front end 201 of the runway 20 and respectively extending upward. The first sensor 51 is disposed on the first support rod 101 . It is worth mentioning that the position where the first sensor 51 is set can obtain the first light pattern provided by the first signal providing component, wherein the first sensor 51 can obtain all or most of the first light pattern. The light pattern, for example, may obtain three-quarters or one-half of the first light pattern, and the present invention is not limited thereto. Moreover, the runway 20 has a track 202 and a base 203 supporting the track 202 .

The signal providing component is used to provide a specific light image. It can be understood that in order to increase the sensing effect of the first sensor 51, the signal providing component can generate a specific light image by actively emitting light. The signal providing component may be, for example, a material with a high reflectance, and generates a specific light image to the first sensor 51 by passively reflecting external light.

In detail, the first signal providing component may be a light emitting component, such as an infrared light, a laser light, or an LED that can actively provide a light beam. Alternatively, the first signal providing component may be a reflective component with a high reflection coefficient, such as a reflective tape, especially a retro-reflector. The first signal providing component can also be formed by glass fluorescent beads. Alternatively, the first signal providing component may be composed of reflective tape and glass fluorescent beads. However, the present invention is not limited thereto. Those skilled in the art can change the material used by the first signal providing component or the type of light source used according to the actual situation and needs, so as to complete the present invention. For the convenience of description, the signal providing components mentioned in the following embodiments are illustrated as reflective components, and the first signal providing component is the first reflective component 41 .

The first sensor 51 is used for acquiring a first image including the imaging content of the first light image. Referring to FIG. 3 , FIG. 3 is a schematic diagram of an embodiment of the first image provided by an embodiment of the present invention. The first image 61 includes a first light pattern 611 provided from the first reflective element 41 , and the first light pattern 611 extends from a first starting point S1 in the first image 61 .

Referring to FIG. 1A again, the first sensor 51 is, for example, a complementary metal-oxide-semiconductor (CMOS) image sensor or a charge-coupled device (CCD) image sensor, which is not limited in this embodiment.

It is worth mentioning that referring to FIG. 1B in conjunction with FIG. 3 , FIG. 1B is a schematic diagram of a first sensor provided by an embodiment of the present invention. The first sensor 51 in the embodiment of the present invention may also have a first light source 71 . The first light source 71 can be disposed on the first sensor 51 to provide a light beam to irradiate the first reflective element 41 to generate the first light pattern 611 , thereby improving the definition of the first light pattern 611 in the first image 61 . The first light source 71 is, for example, an infrared ray or a light emitting diode with a wavelength of 850 nm. It should be understood that the first light emitting source 71 has various changes in different implementation manners, and this embodiment of the present invention is not limited thereto.

Incidentally, in this embodiment, the treadmill M only includes one sensor and one reflective component. However, the present invention is not limited thereto. In other embodiments, the treadmill M may also include multiple sensors and multiple reflective components. The reflective components are arranged on the side of the runway 20 . The sensor may capture light patterns provided by one or more light reflective elements. For the convenience of description, the treadmill M includes only one sensor and one reflective component as an example.

In this embodiment, the first sensor 51 directly outputs the first image 61 to the controller 30 , and the controller 30 performs subsequent calculations according to the imaging characteristics of the first light pattern 611 of the first image 61 . In other embodiments, the first sensor 51 may also include a first image processor (not shown in FIG. 1A ). The first image processor receives the first image 61 and calculates the imaging feature of the first light pattern 611 according to the first image 61 . The first image processor outputs the imaging characteristic of the first light pattern 611 to the controller 30 , so that the controller 30 adjusts the runway 20 according to the imaging characteristic of the first light pattern 611 .

When the user operates the treadmill M, the user's limbs will block the first image 61 acquired by the first signal providing component on the first sensor 51, and then change the imaging characteristics of the first light pattern 611, wherein the imaging characteristics can be It includes the imaging position, imaging length, number of imaging segments or other features that can be used for identification of the first light pattern 611 . Taking the imaging length as an example, when the user is moving on the treadmill M, the reciprocating motion of the user's feet will block the imaging of different regions of the first signal providing component in the first image 61, thereby causing the imaging length of the first light pattern 611 to be generated. For example, when the user's feet are close to the front end 201 of the runway 20, the imaging length of the first section of the first light pattern 611 is shorter, and when the user's feet are far away from the front end 201 of the runway 20, the length of the first light pattern 611 is shorter. The first imaging segment is longer.

Therefore, according to the imaging length of the first imaging segment of the first light pattern 611 , it can be judged whether the position of the user relative to the runway 20 is closer to or farther from the front end 201 when moving. Furthermore, the frequency of change of the first imaging length according to the first light pattern 611 can be used to calculate the step frequency value of the user when running, which is used to provide an analysis of the user's exercise performance.

In terms of calculating the imaging length of the first imaging segment of the first light pattern 611, the controller 30 can directly determine the imaging length of the first light pattern 611 according to the brightness difference between the first light pattern 611 and the background of the first image 61, And the imaging length of the first light pattern 611 is the distance extending from the first starting point S1, or the distance extending from the first starting point S1 along a predetermined direction P, or the longest distance extending from the first starting point S1 along the predetermined direction P. far distance. In this embodiment, the predetermined direction P refers to the direction in which the first light pattern 611 extends from the first starting point S1 to the first end point F1 .

Further, when the positions of the first sensor 51 and the first signal providing component are both fixed, the imaging position of the first light pattern 611 on the first image 61 can be deduced as the imaging length of the first light pattern 611, for example, when When the first light pattern 611 forms an image in a first area of the first image 61, the representative length of the first light pattern 611 is X1, when the first light pattern 611 forms an image in the first area and a second area of the first image 61 , the representative length of the first light pattern 611 is X2, wherein the length X2 is greater than the length X1. Therefore, the imaging length of the first light pattern 611 can be determined according to which regions of the first image 61 are imaged by the first light pattern 611 , and then used to control the running speed of the runway 20 .

Referring again to FIG. 1A , the controller 30 controls the driving module to adjust a running speed of the runway 20 according to the imaging length of at least one light pattern (for example, the first light pattern 611 ). In this embodiment, the controller 30 first receives the first image 61 , and calculates the imaging length of the first light pattern 611 according to the first image 61 , and then adjusts the running speed of the runway 20 accordingly. The controller 30 is a technique commonly used by those skilled in the art to control the computing system, so it will not be repeated here.

Referring to FIG. 1A and FIG. 3 , when the start button (not shown in FIG. 1A ) of the treadmill M is pressed, the first sensor 51 will capture the first image 61 at regular intervals. Since the first reflective component 41 has a high reflection coefficient, the first light pattern 611 reflected by the first reflective component 41 to the first sensor 51 appears in the first image 61 . When there is no object A (such as a user) on the treadmill M, the light beam pattern reflected by the first reflective assembly 41 will not be blocked, so the imaging length of the first light pattern 611 appears to extend from the first starting point S1 to the second One terminal F1.

Referring to FIG. 2 , FIG. 2 is a schematic diagram of a sensing area of a running track in a treadmill provided by an embodiment of the present invention. The track 20 of the treadmill M is at least divided into a first sensing area SR1 adjacent to the first sensor 51 and a second sensing area SR2 adjacent to the first sensing area SR1 . The controller 30 determines that the object A is located in the first sensing area SR1 or the second sensing area SR2 of the runway 20 according to the imaging length of the first light pattern 611 , and then adjusts the running speed of the runway 20 according to the position of the object A accordingly. In fact, in this embodiment, the runway 20 is divided into two regions: the front half area (ie, the first sensing area SR1 ) and the second half area (ie, the second sensing area SR2 ), and after being shaded according to the first light pattern 611 From the presented imaging length, it is determined that object A is located in the area of runway 20 .

Referring to FIGS. 4A and 4B , FIGS. 4A and 4B are schematic views of different first images that are masked according to one embodiment of the present invention. When the object A is located on the runway 20 of the treadmill M, the object A will be located between the first sensor 51 and the first reflective assembly 41, and shield the first light pattern 611 reflected by the first reflective assembly 41 to the first sensor 51, so that The first light pattern 611 is as shown in FIG. 4A or 4B.

As shown in FIG. 4A, when the imaging length extending from the first starting point S1 of the first light pattern 611 is less than a first default value TH1, the controller 30 determines that the object A is located in the first sensing area SR1 of the runway 20, and therefore controls The controller 30 increases the operating speed of the runway 20 correspondingly. Specifically, the controller 30 determines that the moving speed of the object A is greater than the operating speed provided by the runway 20 . Then, the controller 30 directly increases the running speed of the runway 20 through the driving module to match the moving speed of the object A, so that the object A can maintain the middle position of the runway 20 . In this embodiment, the first default value TH1 is designed to be half of the distance from the first start point S1 to the first end point F1 of the first light pattern 611 when there is no object A on the runway 20 . Incidentally, the first default value TH1 provided in this embodiment is only for illustration and is not intended to limit the present invention. Those skilled in the art can design the value of the first default value TH1 according to the actual situation and requirements.

As shown in FIG. 4B, when the imaging length of the first light pattern 611 extending from the first starting point S1 is greater than the first default value TH1, the controller 30 determines that the object A is located in the second sensing area SR2 of the runway 20, so the controller 30 reduces the operating speed of the runway 20 accordingly. Specifically, at this moment the controller 30 determines that the moving speed of the object A is lower than the running speed provided by the runway 20 . Then, the controller 30 directly reduces the running speed of the runway 20 to match the moving speed of the object A through the driving module.

The flow of the track control method for the treadmill M will be further introduced below. In conjunction with FIGS. 2 , 4A and 4B, refer to FIG. 11 . FIG. 11 is a flow chart of a runway control method provided by an embodiment of the present invention. The runway control method in FIG. 11 is applicable to the treadmill M in FIG. 1 . In step S101 , the first sensor 51 captures the first image 61 at regular intervals. The first image 61 includes a first light pattern 611 provided from the first reflective component 41 , and the first light pattern 611 extends from a first starting point S1 in the first image 61 .

In step S102 , the controller 30 receives the first image 61 and calculates the imaging length of the first light pattern 611 according to the first image 61 . Alternatively, in other embodiments, the first image processor of the first sensor 51 may receive the first image 61 and calculate the imaging length of the first light pattern 611 . Next, the first image processor outputs the calculated imaging length of the first light pattern 611 to the controller 30 . In this way, the controller 30 does not need to spend time and hardware resources to calculate the imaging length of the first light pattern 611 . Incidentally, the method for calculating the imaging length of the first light pattern 611 can be referred to above, and will not be repeated here.

In step S103 , the controller 30 determines whether the imaging length of the first light pattern 611 in the image is greater than a first default value TH1 . If the imaging length of the first light pattern 611 in the first image 61 is not greater than the first default value TH1, go to step S104. On the contrary, if the imaging length of the first light pattern 611 in the first image 61 is greater than the first default value TH1, go to step S105. The controller 30 determines that the object A is located in the first sensing area SR1 or the second sensing area SR2 of the runway 20 according to the imaging length of the first light pattern 611 , and adjusts the running speed of the runway 20 accordingly.

In step S104 , the controller 30 determines that the object A is located in the first sensing area SR1 of the runway 20 , that is, the speed of the object A is greater than the running speed of the runway 20 . Next, the controller 30 directly increases the running speed of the runway 20 through the driving module, and returns to step S101. In step S105 , the controller 30 determines that the object A is located in the second sensing area SR2 of the runway 20 , that is, the speed of the object A is lower than the operating speed of the runway 20 . Next, the controller 30 directly reduces the running speed of the runway 20 through the driving module correspondingly, and returns to step S101.

The steps S101-S105 will be executed repeatedly until the stop key (not shown in FIGS. 1 and 2 ) of the treadmill M is pressed to stop the running of the treadmill M. The start key and the stop key on the treadmill M can be separate keys, or be the same key.

On the other hand, the treadmill M may further include a second reflective component 42 , and may further include a second sensor 52 . Referring again to FIG. 2 , the second reflective component 42 is disposed on the second side 205 of the runway 20 and corresponds to the first reflective component 41 . The second sensor 52 is coupled to the controller 30 , and the second sensor 52 is disposed on the second support rod 102 in FIG. 2 . It can be understood that the first sensor 51 can also be arranged at a position where the first reflective component 41 and the second reflective component 42 can be detected simultaneously, so that the second sensor 52 can be replaced by the first sensor 51 .

The second reflective component 42 has a high reflectance, and the second reflective component 42 can be selected from the same or different material as the first reflective component 41, and those skilled in the art can change the second reflective component 42 according to actual conditions and needs. material, to complete the present invention.

The second sensor 52 is used to acquire a second image. The second image includes a second light pattern provided from the second reflective element 42 . The second light pattern extends from a second starting point S2. Similar to the first image 61 , the second light pattern in the second image also changes due to the position of the object A.

The controller 30 may determine that the object A is located in the first sensing area SR1 or the second sensing area SR2 of the runway 20 according to at least one of the imaging length of the first light pattern 611 or the imaging length of the second light pattern. The controller 30 adjusts the running speed of the runway 20 according to the position of the object A correspondingly. The method for the controller 30 to determine the position of the object A according to the imaging length of the first light pattern 611 or the imaging length of the second light pattern is similar to the process shown in FIG. 11 .

Specifically, when the imaging length of the first light pattern 611 changes but the second light pattern is not blocked, the controller 30 acquires the first image 61 to adjust the running speed of the treadmill M. When the first light pattern 611 is not blocked and the imaging length of the second light pattern changes, the controller 30 acquires the second image to adjust the running speed of the treadmill M. When the imaging length of the first light pattern 611 and the imaging length of the second light pattern both change, the controller 30 uses either the first image 61 or the second image to adjust the running speed of the treadmill M.

Wherein, the present invention does not limit the arrangement positions of the first sensor 51 , the second sensor 52 , the first reflective assembly 41 and/or the second reflective assembly 42 . When there is no object A (user) on the treadmill M, the position of the first sensor 51 can be set to obtain the light beam reflected by the first reflective assembly 41, wherein the first sensor 51 can obtain all of the first light pattern 611 Or most of the first light pattern 611 can be obtained, for example, three fourths or one half of the first light pattern 611 can be obtained, and the present invention is not limited thereto. When the object A (user) uses the treadmill M, the light beam reflected by the first reflective assembly 41 will be blocked by the object A, so that the controller 30 adjusts the running track 20 according to the imaging characteristics of the first light pattern 611 . And when there is no object A (user) on the treadmill M, the position set by the second sensor 52 can obtain the light beam reflected by the second reflective assembly 42, wherein the second sensor 52 can obtain all of the second light pattern Or most of the second light pattern can be obtained, for example, three fourths or one half of the second light pattern can be obtained, and the present invention is not limited thereto. When the object A (user) uses the treadmill M, the light beam reflected by the second reflective assembly 42 will be blocked by the object A, so that the controller 30 adjusts the running track 20 according to the imaging characteristics of the second light pattern.

In addition, the second sensor 52 may also include a second image processor. The second image processor is configured to receive the second image, calculate the imaging length of the second light pattern according to the second image, and then output the imaging length of the second light pattern to the controller 30 . The method for the second image processor to calculate the imaging length of the second light pattern is the same as the method for calculating the imaging length of the first light pattern 611 , so it will not be repeated here.

Incidentally, in the embodiment of the present invention, the second sensor 52 may also have a second light source for providing a light beam to irradiate the second reflective component 42 to generate a second light pattern. The second sensor 52 may be the same as or different from the first sensor 51 . The sensor is a technology commonly used in the dynamic tracking system by those skilled in the art, so it will not be repeated here.

The treadmill M provided by the embodiment of the present invention can directly adjust the rotational speed of the runway 20 by judging the position of the user, so the treadmill M can directly provide a speed that meets the physical strength of the user. Therefore, the user does not need to press any additional speed-adjusting buttons when in the exercise state. What's more, when the user cannot keep up with the running speed of the runway 20, there will be no accidents caused by pressing the emergency switch in time. It is worth mentioning that the controller 30 can also output the information of adjusting the running track 20 to the control panel 103, and the control panel 103 reminds the user that the operation of the treadmill M will be adjusted by sound or warning light. In addition, the control panel 103 can also present the user's exercise information at the same time, such as: step frequency, action information.

Referring to FIG. 5 and FIGS. 6A-6C , FIG. 5 is a schematic diagram of a sensing area of a running track in a treadmill provided by another embodiment of the present invention. 6A-6C are schematic diagrams of different first images that are masked according to another embodiment of the present invention. The specific structure of the treadmill M' described in this embodiment has the same structure as that of the treadmill M of said embodiment, and only the differences will be described below.

Different from the treadmill M in FIG. 2, in this embodiment, the runway 20' of the treadmill M' is divided into a first sensing area SR1', a second sensing area SR2' and a third sensing area SR3'. The second sensing region SR2' is located between the first sensing region SR1' and the third sensing region SR3'. The first sensing region SR1' is adjacent to the first sensor 51'. The first sensing region SR1', the second sensing region SR2' and the third sensing region SR3' are arranged in sequence along a track direction Z of the runway 20'. In detail, the first sensing area SR1', the second sensing area SR2' and the third sensing area SR3' correspond to the front section, middle section and rear section of the runway 20'.

The controller 30' determines that the object A' is located in the first sensing area SR1', the second sensing area SR2' or the third sensing area SR3' of the runway 20' according to the imaging length of the first light pattern 611'. The controller 30' adjusts the operating speed of the runway 20' correspondingly according to the position of the object A'. The controller 30' uses a second default value TH2 to determine whether the object A' is located in the first sensing area SR1' or the second sensing area SR2' of the runway 20', and uses a third default value TH3 to determine the object A' It is the second sensing area SR2' or the third sensing area SR3' located on the runway 20'. As for how the controller 30' uses the second default value TH2 and the third default value TH3 to determine whether the object A' is located in the second sensing area SR2' or the third sensing area SR3' of the runway 20', it will be coordinated in the following paragraphs. Figure 12 provides further illustration.

With reference to Fig. 5, 6A-6C, refer to Fig. 12, Fig. 12 is a flowchart of a runway control method provided by another embodiment of the present invention. The runway control method provided in Fig. 12 is applicable to the treadmill M' of Fig. 5 . Steps S201 and S202 are the same as steps S101 and S102 in the above embodiment, so they will not be repeated here, and only steps S203 to S207 will be described below.

In step S203, the controller 30' determines whether the imaging length of the first light pattern 611' in the first image 61' is greater than the second default value TH2, and then determines whether the object A' is located in the first sensing area SR1 of the runway 20' '.

As shown in FIG. 6A, if the imaging length of the first light pattern 611' in the first image 61' is not greater than the second default value TH2, the controller 30' determines that the object A' is located in the first sensing area SR1' of the runway 20' , that is, the user is located in the front section of the runway 20'. The controller 30' determines that the moving speed of the object A' is greater than the running speed provided by the runway 20', and proceeds to step S204. In step S204, the controller 30' directly increases the running speed of the runway 20' through the driving module to match the moving speed of the object A', so that the object A' can maintain the middle position of the runway 20'. Next, return to step S201 to continue to execute the runway control method. If the imaging length of the first light pattern 611' in the first image 61' is greater than the second default value TH2, go to step S205. In step S205, the controller 30' determines whether the imaging length of the first light pattern 611' in the image is greater than the third default value TH3, and then determines whether the object A' is located in the second sensing area SR2' or the third sensing area SR2' of the runway 20'. Survey area SR3'.

As shown in FIG. 6B, if the imaging length of the first light pattern 611' in the first image 61' is not greater than the third default value TH3 (that is, the imaging length of the first light pattern 611' is between the second default value TH2 and the third default value TH3), the controller 30' determines that the object A' is located in the second sensing area SR2' of the runway 20', that is, the user is located in the middle section of the runway 20'. The controller 30' determines that the speed of the object A' is approximately the same as the running speed of the runway 20', and proceeds to step S206. In step S206, the controller 30' maintains the operating speed of the runway 20', and returns to step S201 to continue executing the runway control method.

As shown in FIG. 6C, if the imaging length of the first light pattern 611' in the first image 61' is greater than the third default value TH3, the controller 30' determines that the object A' is located in the third sensing area SR3' of the runway 20', That is, the user is located in the back section of the runway 20'. The controller 30' determines that the speed of the object A' is lower than the operating speed of the runway 20', and proceeds to step S207. In step S207, the controller 30' directly reduces the running speed of the runway 20' through the driving module to match the moving speed of the object A'. Next, return to step S201 to continue to execute the runway control method.

Similarly, the steps S201-S207 will be repeatedly executed until the stop key (not shown in FIG. 5 ) of the treadmill M' is pressed to stop the operation of the treadmill M'.

It should be noted that, in this embodiment, the second default value TH2 is designed to be that when there is no object A' on the runway 20', the first light pattern 611' extends from the first starting point S1' to the first end point F1' for one-third of the distance one. The third default value TH3 is designed to be two-thirds of the distance from the first starting point S1' to the first end point F1' of the first light pattern 611' when there is no object A' on the runway 20'. Incidentally, the second default value TH2 and the third default value TH3 provided in this embodiment are only for illustration and are not intended to limit the present invention. Those skilled in the art can design the values of the second default value TH2 and the third default value TH3 according to the actual situation and requirements.

On the other hand, the treadmill M' of FIG. 5 may also include a second reflective assembly 42' and a second sensor 52'. The position and connection relationship between the second reflective component 42' and the second sensor 52' is similar to that of the second reflective component 42 and the second sensor 52 in the above embodiment, so no more details are given here.

The second sensor 52' is used to acquire a second image. The second image includes a second light pattern provided from the second light reflective element 42'. Similar to the first image 61', the second light pattern in the second image also changes due to the position of the object A'.

The controller 30' may determine that the object A' is located in the first sensing area SR1' and the second sensing area SR1' of the runway 20' according to at least one of the imaging length of the first light pattern 611' or the imaging length of the second light pattern. SR2' or the third sensing region SR3'. The controller 30' adjusts the operating speed of the runway 20' correspondingly according to the position of the object A'. The method for the controller 30' to determine the position of the object A' according to the imaging length of the first light pattern 611' or the imaging length of the second light pattern is similar to the process shown in FIG. 12 .

Specifically, when the imaging length of the first light pattern 611' changes and the second light pattern is not blocked, the controller 30' takes the first image 61' to adjust the running speed of the treadmill M'. When the first light pattern 611' is not blocked and the imaging length of the second light pattern changes, the controller 30' takes the second image to adjust the running speed of the treadmill M'. When the imaging length of the first light pattern 611' and the imaging length of the second light pattern both change, the controller 30' takes either the first image 61' or the second image to adjust the operation of the treadmill M' speed.

In addition, similar to the second sensor 52 of the above embodiment, the second sensor 52' of this embodiment may also include a second image processor and a second light source. The second image processor may pre-process the second image to calculate the imaging length of the second light pattern. The method for the second image processor to calculate the imaging length of the second light pattern is the same as the method for calculating the imaging length of the first light pattern 611', so it will not be repeated here.

It is worth mentioning that, in this embodiment, the runway 20' is divided into three sensing areas. However, the present invention is not limited thereto. In other embodiments, the runway 20' can be divided into multiple sensing areas according to actual conditions and needs. Those of ordinary skill in the art should be able to design the number of sensing regions by themselves after referring to the embodiments, and design default values accordingly, so as to complete the present invention.

Referring to FIG. 7 , FIG. 7 is a schematic diagram of a sensing area of a running track in a treadmill provided by another embodiment of the present invention. Similar to the treadmill M of Fig. 1, the treadmill M in the present embodiment "comprises a runway 20", a first sensor 51", a second sensor 52" and a controller 30". A first runway 20" A first reflective component 41 ″ is disposed on one side 204 ″, and a second reflective component 42 ″ is disposed on a second side 205 ″ of the runway 20 ″. The second side 205 ″ is opposite to the first side 204 ″. The first sensor 51 ″ and the second sensor 52 ″ in this embodiment are the same as those in the above embodiment, and will not be repeated here.

With reference to FIG. 7 , refer to FIGS. 8A and 8B . FIGS. 8A and 8B are schematic diagrams of a first image and a second image provided by yet another embodiment of the present invention, respectively. Specifically, the first sensor 51" obtains the first image 61" shown in FIG. 8A according to the reflected light beam provided by the first reflective assembly 41". The second image 62" shown in 8B. The first light pattern 611" in the first image 61" extends from the first start point S1" to the first end point F1". The second light pattern 621" in the second image 62" extends from the second start point S2" to the second end point F2". The controller 30" performs subsequent calculations according to the imaging length of the first light pattern 611" in the first image 61" and the imaging length of the second light pattern 621" in the second image 62".

Different from the treadmill M of FIG. 2 and the treadmill M' of FIG. 5, the treadmill M" of this embodiment divides the runway 20" into at least a first detection area DR1 and a first detection area DR1 adjacent to the first reflective assembly 41". A second detection region DR2 is adjacent to the second reflective element 42". The controller 30" determines that an object A" is located in the first detection area DR1 or the second detection area DR2 of the runway 20" according to the imaging length of the first light pattern 611" and the imaging length of the second light pattern 621". In fact, In this embodiment, the runway 20" is divided into two areas, the right half area and the left half area. The controller 30" determines that the object A" is located in the area of the runway 20" according to the imaging lengths presented after the first light pattern 611" and the second light pattern 621" are shielded.

Referring to FIGS. 8A and 8B , the first sensor 51 ″ and the second sensor 52 ″ acquire the first image 61 ″ and the second image 62 ″ at the same time. At this time, neither the first light pattern 611" of the first image 61" nor the second light pattern 621" of the second image 62" is blocked by the object A". Therefore, the controller 30" determines that there is no object A" on the runway 20". Object A".

The flow of the method for controlling the runway 20" of the treadmill M" will be further introduced below. With reference to FIG. 7 , refer to FIGS. 9A and 9B and 10A and 10B and 13 . FIGS. 9A and 9B are schematic diagrams of the first image and the second image when the object is located in the first detection area according to another embodiment of the present invention. 10A and 10B are schematic diagrams of a first image and a second image respectively when an object is located in a second detection area according to yet another embodiment of the present invention. Fig. 13 is a flowchart of a runway control method provided by another embodiment of the present invention. The runway control method shown in Figure 13 is applicable to the treadmill M" in Figure 7". In step S301, the first sensor 51 "acquires the first image 61" at regular intervals, and at the same time the second sensor 52" is fixed at regular intervals Time acquires a second image 62".

In step S302, the controller 30" simultaneously receives the first image 61" and the second image 62", and proceeds to step S303 and step S304 respectively. In step S303, the controller 30" calculates the first The imaging length of the light pattern 611", and enter step S305. In step S304, the controller 30" calculates the imaging length of the second light pattern 621" according to the second image 62", and proceeds to step S305. It should be noted that the controller 30" calculates the first light pattern 611" and the second The method of the imaging length of the light pattern 621" can be referred to above, and will not be repeated here.

In step S305, the controller 30" determines whether the imaging length of the first light pattern 611" is greater than the imaging length of the second light pattern 621". According to the imaging length of the first light pattern 611" and the imaging length of the second light pattern 621" length, the controller 30" determines that the object A" is located at the position of the runway 20", and adjusts the runway 20" accordingly in the continuing steps.

As shown in Figs. 9A and 9B, if the imaging length of the first light pattern 611" is greater than the imaging length of the second light pattern 621", go to step S306. In step S306, the controller 30" determines that the object A" is located in the second detection area DR2 of the runway 20". That is to say, the second light pattern 621" generated by the reflection of the light beam by the second reflective component 42" is captured by the second light pattern 621" on the runway 20". user masking. Therefore, the controller 30" determines that the position of the user is adjacent to the second reflective assembly 42", that is, the left side of the runway in FIG. 7, and then enters step S308. In step S308, the controller 30" correspondingly adjusts the runway 20" through the driving module (not shown in FIG. "Move on the side with a smaller slope (adjacent to the first reflective assembly 41"), and then return to step S301.

As shown in Figs. 10A and 10B, if the imaging length of the first light pattern 611" is not greater than the imaging length of the second light pattern 621", go to step S307. In step S307, the controller 30" determines that the object A" is located in the first detection area DR1 of the runway 20". That is to say, the first light pattern 611" generated by the reflection of the light beam by the first reflective component 41" is reflected on the runway 20". user masking. Therefore, the controller 30" determines that the user's position is adjacent to the first reflective assembly 41", that is, the right side of the runway in FIG. 7, and then enters step S309. In step S309, the controller 30" correspondingly adjusts the runway 20" through the control module, such as increasing the slope of the runway 20" adjacent to the side of the first reflective component 41", so that the user faces the runway 20" with a smaller slope (adjacent to the One side of the second reflective assembly 42") moves, and then returns to step S301.

The steps S301-S309 will be executed repeatedly until the stop key (not shown in FIG. 7 ) of the treadmill M" is pressed to stop the operation of the treadmill M".

Through the treadmill M" in the embodiment of the present invention, the track 20" can be adjusted directly by judging the position of the user. Therefore, when the user inertially moves on a specific side of the runway 20", the controller 30" increases the slope of the corresponding area on the runway 20", thereby reducing the user's unsteady stepping due to only moving on a specific side. dangerous situation, and even force the user to keep moving in the middle of the runway to improve the user's exercise posture. In addition, the controller 30" can also reduce the uneven consumption of the runway 20" through the adjustment, so as to prolong the running time of the treadmill. M" service life.

Furthermore, the controller 30" can also judge the movement of the object A" according to the change of the imaging length of the first light pattern 611" over time, or the change of the imaging length of the second light pattern 621" over time. state. In detail, when the user is in different states of motion on the track 20", such as running fast, walking, etc., the frequency of strides will be different. Therefore, by fixedly calculating the imaging length and time of the light patterns 611", 621" The controller 30" can judge the user's exercise state according to the obtained frequency.

In addition, in other embodiments, the first reflective component of the treadmill (such as the first reflective component 41, 41 ′ or 41 ″) and the second reflective component (such as the second reflective component 42, 42 'or 42") can be replaced by the first light emitting component and the second light emitting component. Therefore, in other embodiments, the first light-emitting component can emit a light beam to the first sensor (such as the first sensor 51, 51' or 51"), so as to provide the first sensor to obtain the first light pattern, and the second The source of the two light-emitting components can emit a light beam to the second sensor (such as the first sensor 52, 52' or 52''), so that the second sensor can obtain the second light pattern. In addition, the structure of the treadmill and the control mode of the runway thereof are identical with the described embodiment. Therefore, those of ordinary skill in the art should be able to make simple substitutions to complete the present invention, and details will not be repeated here.

Referring to FIG. 14A and FIG. 14B , FIG. 14A is a schematic diagram of a treadmill provided by another embodiment of the present invention, and FIG. 14B is a schematic diagram of an image sensor provided by another embodiment of the present invention. As shown in the figure, the embodiment of the present invention provides a treadmill N, which includes a track 20 , an image sensor 53 and a controller 70 . The controller 70 is coupled to the image sensor 53 . In detail, the treadmill N also has a support body 10 and a control panel 103 mounted on the support body 10 . The controller 70 can be disposed in the control panel 103 . The control panel 103 provides relevant information such as the user's running speed, time and warnings, and can directly adjust the track 20 through the information. The support body 10 has a first support rod 101 and a second support rod 102 disposed on two opposite sides of a front end 201 of the runway 20 and respectively extending upward. The runway 20 has a track 202 and a base 203 supporting the track 202 . Subject A is a user who uses a treadmill N.

As shown in FIG. 14B , the image sensor 53 has an image sensing unit 531 . The image sensor 53 in the embodiment of the present invention can also have a light source 533 . The light source 533 may be an invisible light source, such as an infrared light or a light emitting diode with a wavelength of 850 nm. It should be understood that the light emitting source 533 has various changes in different implementations, and this embodiment of the present invention is not limited thereto.

Incidentally, in this embodiment, the treadmill N only includes one image sensing unit and one light emitting source, however, the present invention does not limit the number of image sensing units and light emitting sources. The following will take the treadmill N including only one image sensing unit and one light source as an example for illustration.

The image sensing unit 531 of the image sensor 53 is used to acquire an image including the object A (the user of the treadmill N). Since the image sensing unit 531 is an image sensing unit with a plurality of pixels, the captured image also has a plurality of pixels. The image sensing unit 531 can acquire an image containing the object A at regular intervals, and the controller 70 can adjust the running speed of the runway 20 according to the imaging feature of the object A in the image, wherein the imaging feature can be, for example, the object A The proportion or distribution of pixels within the image. The specific operation details will be described in detail below.

Please refer to Figures 15A, 15B and 15C, and please also refer to Figure 14A. 15A , 15B and 15C are schematic diagrams of different images captured by the image sensing unit provided by another embodiment of the present invention, respectively. As shown in FIG. 15A , the image 151 is an image including the object A captured by the image sensing unit 531 . Wherein, the image corresponding to the object A in the image 151 is an image 1511, and the image 1511 corresponding to the object A is also composed of a plurality of pixels. Since the image sensor 53 is arranged at the front end of the treadmill N relative to the object A, the higher the ratio of the image 1511 corresponding to the object A to the pixels in the image 151, the closer the object A is to the front end 201 of the treadmill N. close. The lower the ratio of the image 1511 to the pixels in the image 151 is, the farther the object A is from the front end 201 of the treadmill N. The controller 70 can adjust the running speed of the runway 20 according to the ratio of the pixels of the image 1511 in the image 151 , so that the object A can be kept in the middle of the runway 20 .

As shown in FIG. 15B , in an embodiment of the present invention, the image sensing unit 531 acquires an image 152 including the object A. Referring to FIG. Wherein, the image corresponding to the object A in the image 152 is the image 1521 . Compared with the image 151 shown in the embodiment of FIG. 15A , the proportion of pixels occupied by the image 1521 in the image 152 is higher than the proportion of pixels occupied by the image 1511 in the image 151 . Therefore, it can be seen that the object A in the embodiment shown in FIG. 15B is closer to the front end 201 of the treadmill N than in the embodiment shown in FIG. 15A .

As shown in FIG. 15C , the image sensing unit 531 acquires an image 153 including the object A. Referring to FIG. Wherein, the image corresponding to the object A in the image 153 is the image 1531 . Compared with the image 151 shown in FIG. 15A , the proportion of pixels occupied by the image 1531 in the image 153 is lower than the proportion of pixels occupied by the image 1511 in the image 151 . Therefore, it can be seen that the object A in the embodiment shown in FIG. 15C is farther away from the front end 201 of the treadmill N than in the embodiment shown in FIG. 15A .

The controller 70 can know the distance between the object A and the front end 201 of the treadmill N according to the ratio of the pixels of the image corresponding to the object A in the image acquired by the image sensor 53, and then adjust the running speed of the track 20, so that Object A is able to remain in the middle of runway 20 .

In an embodiment of the present invention, the controller 70 can set a default value (not shown in the figure), and the default value is a proportion of the pixels corresponding to the image corresponding to the object A in the image acquired by the image sensing unit 531 value. When the image captured by the image sensing unit 531 has a pixel ratio of the image corresponding to the object A greater than the default value, it means that the object A is too close to the front end 201 of the treadmill N, and the moving speed of the object A is faster than that of the track 20. provided speed. At this time, the controller 70 directly increases the running speed of the runway 20 through a driving module (not shown in the figure), so that the object A can be maintained in the middle of the runway 20 . Wherein, those of ordinary skill in the art can design the numerical value of the default value by themselves according to the actual situation and demand to complete the present invention.

In an embodiment of the present invention, the controller 70 may set a default value (not shown in the figure), and the default value is a ratio of the pixels corresponding to the image corresponding to the object A in the image captured by the image sensing unit 531 value. When the image captured by the image sensing unit 531 has a pixel ratio of the image corresponding to the object A that is smaller than the default value, it means that the object A is too far away from the front end 201 of the treadmill N, and the moving speed of the object A is slower than that of the track 20. provided speed. At this time, the controller 70 will reduce the operating speed of the runway 20 so that the object A can be kept in the middle of the runway 20 . Wherein, those of ordinary skill in the art can design the numerical value of the default value by themselves according to the actual situation and demand to complete the present invention.

In an embodiment of the present invention, when the proportion of pixels corresponding to the image corresponding to the object A in the image acquired by the image sensing unit 531 gradually increases, it means that the object A is getting closer to the front end 201 of the treadmill N, The speed at which object A is moving is progressively greater than that provided by runway 20 . At this time, the controller 70 may gradually increase the running speed of the runway 20 so that the object A can be maintained in the middle of the runway 20 .

In an embodiment of the present invention, when the proportion of pixels in the image captured by the image sensing unit 531 corresponding to the object A gradually decreases, it means that the object A is getting farther and farther away from the front end 201 of the treadmill N, and the object A is moving at progressively lower speeds than runway 20 provides. At this time, the controller 70 can gradually reduce the operating speed of the runway 20 so that the object A can be maintained in the middle of the runway 20 .

In an embodiment of the present invention, the controller 70 may set a default value (not shown in the figure), and the default value is a ratio of the pixels corresponding to the image corresponding to the object A in the image captured by the image sensing unit 531 value. When the image captured by the image sensing unit 531 has a pixel ratio of the image corresponding to the object A greater than the default value, the controller 70 will activate the runway 20 to run. That is, when the object A (user) is at an appropriate position on the running track 20 of the treadmill N, in the image acquired by the image sensing unit 531, the proportion of the pixels corresponding to the image of the object A will reach the preset default value, then Based on this, the controller 70 determines that the user is ready to use the treadmill N, and thus starts the runway 20 to run. Wherein, those of ordinary skill in the art can design the numerical value of the default value by themselves according to the actual situation and demand to complete the present invention.

In an embodiment of the present invention, the controller 70 may set a default value (not shown in the figure), and the default value is a ratio of the pixels corresponding to the image corresponding to the object A in the image captured by the image sensing unit 531 value. When the image captured by the image sensing unit 531 has a pixel ratio of the image corresponding to the object A that is smaller than the default value, the controller 70 stops running the runway 20 . That is, when the object A (user) is not in front of the treadmill N, or when the object A is not in a proper position on the runway 20, in the images captured by the image sensing unit 531, the proportion of the pixels corresponding to the image of the object A If the value is too small, the controller 70 judges that the user is not using the treadmill N, so the running of the runway 20 is stopped. Wherein, those of ordinary skill in the art can design the numerical value of the default value by themselves according to the actual situation and demand to complete the present invention.

In an embodiment of the present invention, the controller 70 can calculate the step frequency value of the user when running according to the pixel change frequency of the object A in the image captured by the image sensing unit 531 , so as to provide an analysis of the user's sports performance.

Wherein, the image sensor 53 is a technology commonly used in dynamic tracking systems by those skilled in the art, and its operation details will not be repeated here. The operation of the controller 70 is also commonly used by those skilled in the art in the control computing system, so it will not be repeated here.

In an embodiment of the present invention, the light source 533 of the image sensor 53 is used to emit a light (not shown) to the object A. Referring to FIG. Among the images acquired by the image sensing unit 531 , the image corresponding to the object A is formed by the reflection of the light emitted by the light source 533 . The light emitted by the light source 533 may be, for example, an invisible light, but the present invention is not limited thereto. Therefore, through the setting of the light source 533, it can be ensured that the treadmill of the present invention can run smoothly in any environment. This avoids the problem that the image sensing unit 531 cannot acquire the image of the object A correctly, for example, in the occasion of dim light or complex light.

Through the treadmill N provided by the embodiment of the present invention, the running of the track 20 can be started, stopped or adjusted directly by judging the position of the user, so the treadmill N can directly provide a speed in line with the physical strength of the user. Therefore, the user does not need to press any additional speed-adjusting buttons when in the exercise state. What's more, when the user cannot keep up with the running speed of the runway 20, there will be no accidents caused by pressing the emergency switch in time. It is worth mentioning that the controller 70 can also output the information of adjusting the running track 20 to the control panel 103, and the control panel 103 reminds the user that the operation of the treadmill N will be adjusted by means such as sound or warning lights. In addition, the control panel 103 can also present the user's exercise information at the same time, such as: speed, action information and so on.

The flow of the runway control method for the treadmill N will be further introduced below. Please refer to Figure 16, and cooperate with Figures 14A and 14B. Fig. 16 is a flow chart of a runway control method provided by another embodiment of the present invention. The track control method of the embodiment shown in FIG. 16 is applicable to the treadmill N shown in FIG. 14A. In this embodiment, the controller 70 can set a default value TH161 and a default value TH163. The default value TH161 and the default value TH163 are respectively a proportion value of the pixels corresponding to the image corresponding to the object A in the image acquired by the image sensing unit 531 .

In step S161 , the image sensing unit 531 of the image sensor 53 acquires an image including the object A (the user of the treadmill N). Since the image sensing unit 531 has a plurality of pixels, the captured image also has a plurality of pixels.

Next, in step S162 , the controller 70 determines whether the ratio of the pixels of the image corresponding to the object A in the image acquired by the image sensing unit 531 is smaller than the default value TH161 . If yes, go to step S163; otherwise, go to step S164. Step S163, since the image captured by the image sensing unit 531, the pixel ratio of the image corresponding to the object A is smaller than the default value TH161, it means that the object A is too far away from the front end 201 of the treadmill N, and the moving speed of the object A is slower than the running track 20 provided speed. At this time, the controller 70 directly reduces the operating speed of the runway 20 through a driving module (not shown in the figure), so that the object A can be maintained in the middle of the runway 20 . Next, return to step S161 to continue to execute the runway control method.

In step S164 , the controller 70 determines whether, among the images acquired by the image sensing unit 531 , the proportion of the pixels of the image corresponding to the object A is greater than the default value TH163 ? If yes, proceed to step S165, otherwise return to step S161 to continue to execute the runway control method. Step S165, since the proportion of pixels in the image captured by the image sensing unit 531 corresponding to the object A is greater than the default value TH163, it means that the object A is too close to the front end 201 of the treadmill N, and the moving speed of the object A is greater than The speed provided by runway 20. At this time, the controller 70 increases the running speed of the runway 20 so that the object A can be kept in the middle of the runway 20 .

Incidentally, the default value TH161 and the default value TH163 provided in this embodiment are only for illustration, and are not intended to limit the present invention.

Next, in step S172 , the controller 70 determines whether, among the images acquired by the image sensing unit 531 , the proportion of the pixels corresponding to the image corresponding to the object A gradually decreases. If yes, go to step S173; otherwise, go to step S174. Step S173, since the proportion of the pixels of the image corresponding to the object A gradually decreases in the image acquired by the image sensing unit 531, it means that the object A is getting farther and farther away from the front end 201 of the treadmill N, and the moving speed of the object A is gradually less than The speed provided by runway 20. At this time, the controller 70 will gradually reduce the operating speed of the runway 20 so that the object A can be kept in the middle of the runway 20 . Then, return to step S171 to continue to execute the runway control method.

In step S174, the controller 70 determines whether, among the images acquired by the image sensing unit 531, the proportion of the pixels corresponding to the image corresponding to the object A gradually increases? If yes, proceed to step S175, otherwise return to step S171 to continue to execute the runway control method. Step S175, since the proportion of the pixels of the image corresponding to the object A gradually increases in the image acquired by the image sensing unit 531, it means that the object A is getting closer to the front end 201 of the treadmill N, and the moving speed of the object A is gradually greater than The speed provided by runway 20. At this time, the controller 70 will gradually increase the operating speed of the runway 20 so that the object A can be maintained in the middle of the runway 20 .

The default value TH181 and the default value TH183 are respectively a proportion value of the pixels corresponding to the image corresponding to the object A in the image acquired by the image sensing unit 531 .

In step S181 , the image sensing unit 531 of the image sensor 53 acquires an image including the object A (the user of the treadmill N). Since the image sensing unit 531 has a plurality of pixels, the captured image also has a plurality of pixels.

Next, in step S182, the controller 70 determines whether, among the images acquired by the image sensing unit 531, the proportion of pixels corresponding to the image corresponding to the object A is greater than the default value TH181? If yes, proceed to step S183, otherwise return to step S181 to continue to execute the runway control method. Step S183, since the image captured by the image sensing unit 531, the proportion of pixels corresponding to the image corresponding to the object A is greater than the default value TH181, the controller 70 determines that the object A (user) is located at the track 20 on the treadmill N In place, the controller 70 will activate the runway 20 for operation.

Next, in step S184, the controller 70 determines whether, among the images acquired by the image sensing unit 531, the proportion of the pixels of the image corresponding to the object A is smaller than the default value TH183? If yes, go to step S185, if not, go to step S186 to maintain the operation of the runway 20. In step S185, since the image acquired by the image sensing unit 531, the proportion of pixels corresponding to the image corresponding to the object A is smaller than the default value TH183, the controller 70 determines that the object A is not at an appropriate position on the runway 20, and the controller 70 Operations on runway 20 will be suspended.

Please refer to FIG. 19 and FIG. 20A to FIG. 20B . FIG. 19 is a schematic diagram of the detection area of the running track in the treadmill provided by another embodiment of the present invention. 20A and 20B are schematic diagrams of different images captured by the image sensing unit provided by another embodiment of the present invention, respectively. Similar to the treadmill N of FIG. 14A, the treadmill N' in this embodiment includes a track 20', an image sensor 53' and a controller 70'. The controller 70' is coupled to the image sensor 53'. In detail, the treadmill N' also has a support body 10, and a control panel 103 installed on the support body 10. The controller 70' can be arranged in the control panel 103. The bracket body 10 has a first support rod 101 and a second support rod 102 which are arranged on two opposite sides of a front end 201 of the runway 20' and extend upward respectively. The runway 20 has a track 202 and a base 203 supporting the track 202 . Subject A' is a user using treadmill N'. The specific structure of the treadmill N' described in the present embodiment has the same structure as the treadmill N of the described embodiment, and only the differences will be described below.

Different from the treadmill N in FIG. 14A, the treadmill N' of this embodiment divides the runway 20' into at least a first detection area DR1' adjacent to a first side 214 and a second detection area DR1' adjacent to a second side. 215 of a second detection area DR2'. The image sensor 53' is located between the first side 214 and the second side 215. For example, as shown in FIGS. 20A-20B , the images 191, 192 captured by the image sensing unit of the image sensor 53' are divided into the first image areas 1911, 1921 adjacent to the first side 214 of the runway 20', and the adjacent The second image area 1913, 1923 on the second side 215 of the runway 20'.

In this embodiment, the controller 70' determines that the object A' is located in the first detection area DR1' of the runway 20' according to the position of the image corresponding to the object A' in the image captured by the image sensing unit of the image sensor 53' Or the second detection zone DR2', and adjust the runway 20' accordingly.

As shown in FIG. 20A, in one embodiment of the present invention, the controller 70' can set a default value (not shown in the figure), and the default value is the area occupied by the image corresponding to the object A' in the first image area 1911. A scale value for pixels. In this embodiment, among the images 191 captured by the image sensing unit of the image sensor 53', the image corresponding to the object A' is the image 1915. When the proportion of the pixels of the image 1915 corresponding to the object A' in the first image area 1911 is greater than the default value, the controller 70' determines that the object A' is located in the first detection area DR1' of the runway 20'.

At this time, the controller 70' can correspondingly adjust the runway 20' through the driving module (not shown in the figure), for example, increase the slope of the runway 20' adjacent to the first side 214, so that the user can go up the slope towards the runway 20' The smaller side (adjacent to the second side 215) moves so that object A' can remain in the middle of the runway 20'.

As shown in FIG. 20B , in one embodiment of the present invention, the controller 70' can set a default value (not shown in the figure), which is the area occupied by the image corresponding to the object A' in the second image area 1923 A scale value for pixels. In this embodiment, among the images 192 captured by the image sensing unit of the image sensor 53', the image corresponding to the object A' is the image 1925. When the proportion of the pixels of the image 1925 corresponding to the object A' in the second image area 1923 is greater than the default value, the controller 70' determines that the object A' is located in the second detection area DR2' of the runway 20'.

At this time, the controller 70' can correspondingly adjust the runway 20' through the driving module (not shown in the figure), for example, increase the slope of the runway 20' adjacent to the second side 215, so that the user can go up the slope towards the runway 20' The smaller side (adjacent to first side 214) moves so that object A' can remain in the middle of runway 20'.

Next, in step S212, the controller 70' judges whether the proportion of pixels in the first image area corresponding to the image corresponding to the object A' is greater than the default value TH211? If yes, go to step S213; otherwise, go to step S215. In step S213, since the proportion of pixels in the first image area of the image corresponding to the object A' is greater than the default value TH211, the controller 70' determines that the object A' is located in the first detection area DR1' of the runway 20'. Next, in step S214, the controller 70' adjusts the runway 20' accordingly, such as increasing the slope of the runway 20' adjacent to the first side 214, so that the user has a smaller slope toward the runway 20' (adjacent to the second side 215) side movement. Next, return to step S211 to continue to execute the runway control method.

In step S215, the controller 70' determines whether the proportion of pixels in the second image area corresponding to the image corresponding to the object A' is greater than the default value TH213? If yes, proceed to step S216, otherwise return to step S211 to continue to execute the runway control method. In step S216, since the proportion of pixels occupied by the object A' in the second image area is greater than the default value TH213, the controller 70' determines that the object A' is located in the second detection area DR2' of the runway 20'. Next, in step S217, the controller 70' adjusts the runway 20' accordingly, such as increasing the slope of the runway 20' adjacent to the second side 215, so that the user has a smaller slope toward the runway 20' (adjacent to the first side 214) side movement. Next, return to step S211 to continue to execute the runway control method.
