step 100, carrying out three-dimensional modeling on a real scene to obtain a three-dimensional simulation environment the same as the real scene; wherein the three-dimensional simulation environment comprises: an identification device disposed within the three-dimensional simulation environment.

In step 100, in order to perform three-dimensional modeling on a real scene, a three-dimensional simulation environment identical to the real scene is obtained, and the real scene is converted into a virtual three-dimensional simulation environment. And setting the identification equipment set in the real scene into the three-dimensional scene, or after obtaining the three-dimensional simulation environment, distributing by using an identification equipment distribution method based on the shortest path or an identification equipment distribution method based on the visibility index, wherein the identification equipment distribution method based on the visibility index is as follows:

And setting the distributed identification equipment in a three-dimensional simulation environment to obtain a three-dimensional simulation environment comprising the identification equipment, and obtaining the position information of the identification equipment in the three-dimensional simulation environment.

Storing location information identifying a device setup in a three-dimensional simulation environment in the server.

The process of three-dimensionally modeling a real scene to obtain a three-dimensional simulation environment the same as the real scene, and allocating identification equipment in the three-dimensional simulation environment can also be completed by adopting other modeling and identification equipment allocation methods in the prior art, and the description is omitted.

After obtaining the three-dimensional simulation environment the same as the real scene, the staff can store the data collected by the probe equipment and the image acquisition equipment arranged in the real scene in the server; and the server obtains the path walking information by analyzing the data acquired by the probe equipment and the image acquisition equipment which are arranged in the stored real scene. The specific data acquisition process and data analysis process are prior art and are not described herein.

The path walking information includes: a route start point, a route end point, a route trajectory between the route start point and the route end point, and a route travel time.

The identification device is used for indicating the walking direction; including but not limited to: direction indicators, sound source devices, and navigation display devices.

The sound source device is used for emitting voice indicating the direction.

In one embodiment, the speech uttered by the sound source device may be, but is not limited to: "please ask customers (passengers) who need to go to XXX to turn right after going 100 meters forward" or ask customers (passengers) who go to YYY to turn left and go 30 meters forward.

The flight display equipment is arranged in an airport hall and used for displaying flight information in an airport, and the flight information comprises: the flight number, consignment luggage location, boarding gate, boarding time, destination and other information of each flight, the navigation display equipment is used for shunting, and guiding a person to find the next-level identification according to the purpose of the person, for example, the passenger needs to enter an airport hall to check in, the identification is the airport hall, and after the passenger sees the flight information displayed on the navigation display equipment, checks in and boards according to the flight information displayed on the navigation display equipment.

And 102, acquiring the path walking information of the pedestrian in the real scene.

104, determining an abnormal walking path in the real scene according to the path walking information, and setting the determined abnormal walking path in the three-dimensional simulation environment; the abnormal walking path is provided with a verification position, and the starting point position of the abnormal walking path is provided with identification equipment.

In step 104, in order to determine the abnormal walking path in the real scene, the following specific steps (1) to (4) may be performed:

(1) determining a navigation path between the path starting point and the path end point;

(2) in the plane where the navigation path and the path track are located, from the starting point of the navigation path, making a perpendicular line from the path track to the navigation path;

(3) calculating the distance between the intersection point of the navigation path and the vertical line and the intersection point of the path track and the vertical line;

(4) when the calculated distance is larger than the distance threshold, determining a path track between the identification devices on two sides of the perpendicular line as an abnormal walking path in the real scene, and using an intersection point of the path track and the perpendicular line as a verification position, wherein the identification devices on two sides of the perpendicular line are used as a starting point position and an end point position of the abnormal walking path.

In the step (1), the server further stores navigation software, and in order to determine a navigation path between a path starting point and a path ending point in a real scene, the server may first find a position where the path starting point is located and a position where the path ending point is located in a three-dimensional simulation environment, and then obtain the navigation path between the path starting point and the path ending point by using the navigation software.

And the navigation path is used for representing the optimal walking path between the path starting point and the path ending point.

In the step (2), the length of the perpendicular line from the path trajectory to the navigation path is used to represent the distance between the path trajectory actually traveled by the pedestrian and the navigation path, that is, the error between the path trajectory actually traveled by the pedestrian and the navigation path.

In the step (3), when the distance between the intersection point of the navigation path and the perpendicular line and the intersection point of the path trajectory and the perpendicular line is calculated, the first coordinate of the intersection point of the navigation path and the perpendicular line and the second coordinate of the intersection point of the path trajectory and the perpendicular line may be determined, then the distance between the first coordinate indication position and the second coordinate indication position may be calculated according to the obtained first coordinate and second coordinate, and the calculated distance between the first coordinate indication position and the second coordinate indication position may be used as the distance between the intersection point of the navigation path and the perpendicular line and the intersection point of the path trajectory and the perpendicular line.

In the step (4), the distance threshold is stored in the server in advance.

When the calculated distance is greater than the distance threshold, it is indicated that an error between the path trajectory actually traveled by the pedestrian and the navigation path is large, then, in the three-dimensional simulation environment, the identification devices located on two sides of the perpendicular line are found, and the path trajectory between the identification devices located on two sides of the perpendicular line is determined as an abnormal travel path in the real scene.

Referring to fig. 2, a schematic diagram of an abnormal walking path is shown, wherein, in fig. 2, a direction indicator a indicating straight walking and a direction indicator C indicating turning to the left are provided, and at the position of the intersection B in fig. 2, since the pedestrian cannot find the direction indicator C, after the position of the intersection B lingers for a period of time, it is determined that the road is the correct road to walk straight at the intersection, and the navigation path between the direction indicator a and the direction indicator C is a road segment in the shape of "┎"; and determining the path track traveled by the pedestrian between the direction indicator A and the direction indicator C as the abnormal walking path in the real scene under the condition that the distance between the position (namely the position with the path track farthest from the position of the intersection B in the figure 2) where the pedestrian roams when the intersection B is calculated and the position of the intersection B is greater than the distance threshold.

In another embodiment, an abnormal walking path in the real scene can be determined through the following steps (11) to (13):

(11) determining a path length of the path trajectory;

(12) calculating the path advancing speed of the pedestrian according to the path length of the path track and the path advancing time;

(13) and when the calculated path traveling speed of the pedestrian is less than or equal to a traveling speed threshold value, determining the path track as an abnormal traveling path in the real scene, and taking the position where the abnormal traveling path passes as a verification position.

In the step (11), the server may obtain the path trajectory, and the process of determining the path length of the path trajectory according to the path trajectory is the prior art, and is not described herein again.

In the step (13), the traveling speed threshold value is used to indicate a normal traveling speed of the pedestrian, and is cached in the server in advance.

After the abnormal walking path in the real scene is determined through the above step 104, the following step 106 may be continued.

Step 106, when a digital twin person which does not perform identification device distribution verification in the abnormal walking path exists, acquiring the digital twin person which performs identification device distribution verification on the abnormal walking path from a digital twin person set; wherein, each digital twin person in the digital twin person set is a simulation model with perception areas of different ranges.

In step 106, the sensing region includes: the auditory range and the visual range.

The visual range includes: the viewing distance and the viewing angle.

The visual range is that a camera imaging mode is adopted, the optimal visual field area of a person is in the range of 0-15 degrees, the surrounding environment is shot at the position where the digital twin is located and the visual field angle is 15 degrees, a picture of the surrounding environment is obtained, and whether the identification equipment exists in the surrounding environment is identified by utilizing an AI identification technology.

The sizes of pixels occupied by the marks in the distinguishable images are different due to different eyesight of people, for example, the eyesight of a digital twin person A is good, the number of pixels occupied by the distinguishable characters in the images is 5 multiplied by 5 pixels, the eyesight of a digital twin person B is weak, and the number of pixels occupied by the distinguishable characters in the images is 10 multiplied by 10 pixels. When the digital twin people can recognize the identification information in the image by using an AI recognition technology, the digital twin people are instructed to walk according to the identified semantic information.

Therefore, the field angle of the digital twin can be set to any field angle in the range of 0-15 °; the visual distance of the digital twin can be set to any visual distance between 100 and 150 meters.

The hearing range, i.e. the audible distance

Since the sound source device produces sound outwards, the sound source device can be regarded as a point sound source, and the point sound source radiates outwards and the sound is attenuated, so that the spherical distribution law is followed. The expression of spherical sound wave attenuation along with distance at normal temperature is as follows:

wherein

Is the distance from the sound source device,

for correction of the coefficients, the free space is

Semi-free space

。

For a distance of from the sound source equipment of

The sound pressure level of the location of (a),

is the sound pressure level at the sound source equipment, in decibels (dB), distance

And

the difference in sound pressure level between is:

when in use

The attenuation is 6dB, i.e. the distance-doubled sound pressure level is attenuated by 6 dB.

The noise of a place with dense people flow is generally larger, and many researches show that the noise in most places with dense people flow exceeds 70dB, the sound which can be distinguished by people is 10-15 dB higher than the environmental noise, the sound pressure level at a position 1 meter away from sound source equipment in the places with dense people flow is assumed to be 120dB, the sound pressure level is reduced by 6dB when the distance is increased by 1 time, and the sound content can be distinguished only when people hear 84dB in the places with dense people flow. Since the sound pressure level at 2 meters is 114dB and the sound pressure level at 64 meters is 84dB, a person can recognize sound only within a range of 64 meters from the sound source device, and thus in this environment, the audible distance of the digital twin person is set to 64 meters, that is, when the sound source device sounds within a range of 64 meters from the digital twin person, the voice identification signal can be received.

The digital twin man is arranged, so that the walking process of a pedestrian in a real environment for searching the identification equipment can be simulated, and whether the distribution of the identification equipment is effective or not is verified.

When the digital twin person is placed in the three-dimensional simulation environment, the digital twin person identifies the identification equipment in the set hearing range and visual range and walks according to the indication direction of the identification equipment.

And 108, placing the digital twin person at the starting point position of the abnormal walking path in the three-dimensional simulation environment, and controlling the digital twin person to walk in the direction indicated by the identification equipment arranged at the starting point position of the abnormal walking path.

And step 110, when the digital twin person walks to the verification position of the abnormal walking path and the indication direction of the identification device is not obtained in the walking direction at the verification position, controlling the digital twin person to generate a random number, and determining the walking direction according to the generated random number so that the digital twin person walks in the determined walking direction.

In the above step 110, in order to determine a walking direction from the generated random numbers, the following steps (1) to (2) may be performed:

(1) determining a numerical range to which the random number belongs;

(2) and determining the direction corresponding to the numerical range to which the random number belongs as the walking direction.

In the step (1), the server stores a correspondence between a numerical range and a traveling direction in advance.

In one embodiment, the correspondence between the numerical range and the walking direction can be expressed as follows:

1-30 continuously walking forwards according to the current direction

31-35 travel in the opposite direction to the current direction

36-45 turning and walking to the left side of the current direction

46-55 turn right in the current direction and walk

56-62 turn to the left rear side of the current direction and walk in parallel

62-69 turn and walk in parallel to the right rear side of the current direction

70-84 turns to the left front side of the current direction and walks in parallel

85-100 turns to the right front side of the current direction and walks in parallel

Then, when the digital twin person walks to the verification position of the abnormal walking path and it is determined at the verification position that the direction indicated by the identification device is not obtained in the walking direction, the digital twin person is controlled to generate a random number between 1 and 100, and then the numerical range to which the random number belongs is determined from the correspondence relationship between the numerical range and the walking direction.

For example: when the random number generated by the digital twin person is 26, determining that 26 is in a numerical range of 1-30, and controlling the digital twin person to continue walking forwards according to the current direction.

And 112, when the digital twin person walks in the determined walking direction and obtains the indication of the identification device in the determined walking direction, controlling the digital twin person to walk in the direction indicated by the identification device.

And step 114, when the time length of the digital twin person walking in the walking direction determined by the generated random number reaches the time threshold, determining that the digital twin person cannot reach the end point position of the abnormal walking path, and acquiring the position information of the identification device which is not sensed by the digital twin person.

In step 114, the time threshold is pre-cached in the server and is used to indicate the maximum route search time of the pedestrian in the real environment, and when the maximum route search time is exceeded, the pedestrian will seek help.

The identification device which is not sensed by the digital twin person is the identification device which is closest to the digital twin person between the verification position and the end position of the abnormal walking path.

And step 116, obtaining the adjustment information of the identification equipment which is not sensed by the digital twin by using the obtained position information of the identification equipment.

In the above step 116, in order to obtain the adjustment information of the identification device which is not perceived by the digital twin, the following steps (1) to (2) may be performed:

(1) when the identification device which is not perceived by the digital twin is determined to be not in the perception area range of the digital twin according to the obtained position information of the identification device, obtaining and recording the adjustment information of adding the identification device at the verification position;

(2) when the identification device which is not perceived by the digital twin is determined to be in the range of the perception area of the digital twin according to the obtained position information of the identification device, and an obstacle exists between the identification device which is not perceived by the digital twin and the verification position, the adjustment information for moving the position of the identification device which is not perceived by the digital twin is obtained.

In the above step (1), see fig. 3a, fig. 3b, fig. 3c for a schematic diagram of a digital twin imperceptible identification device, wherein fig. 3a shows that the identification device is not within the perception area of the digital twin due to the imperceptible identification device (direction indicator) being outside the visual range of the digital twin; fig. 3b shows that the identification device (direction indicator) is not within the sensing range of the digital twin due to the fact that it is not sensed outside the field angle of the digital twin; fig. 3c shows that the identification device (sound source device) is not within the sensing area of the digital twin due to the fact that the digital twin is at a greater distance from the non-sensed identification device than the range of the identification device.

Wherein, the adjustment information of adding the identification device at the verification position is recorded and used for indicating that the identification device is added at the verification position.

In the above step (2), fig. 3d and fig. 3e show schematic diagrams of the identification device which is not sensed by the digital twin, wherein fig. 3d shows that although the identification device (direction indicator) which is not sensed by the digital twin is within the sensing area of the digital twin, the identification device which is not sensed by the digital twin due to the obstacle existing between the identification device which is not sensed by the digital twin and the digital twin; fig. 3e shows that although the identification device not perceived by the digital twin (sound source device) is within the perception area of said digital twin, the presence of an obstacle between the identification device not perceived by the digital twin and the digital twin results in that the identification device is not perceived by said digital twin.

And recording the adjustment information of the position of the identification equipment which is not sensed by the digital twin, wherein the adjustment information is used for indicating the position of the mobile identification equipment, so that the mobile identification equipment is not blocked by the barrier any more.

Whether an obstacle exists between the identification device and the verification position, which is not sensed by the digital twin, is determined by the server in the three-dimensional simulation environment according to the identification device and the positions of facilities around the identification device, and the specific process is the prior art and is not repeated here.

To sum up, in the verification method for identifier device allocation proposed in this embodiment, a three-dimensional simulation environment identical to a real scene is obtained by modeling the real scene, then an abnormal walking path in the real scene is set in the three-dimensional simulation environment, a digital twin person with different perception area ranges is placed at a starting point of the abnormal walking path in the three-dimensional simulation environment, the digital twin person is controlled to walk in a direction indicated by an identifier device set at the starting point of the abnormal walking path, and when the digital twin person walks in a determined walking direction, and an indication of the identifier device is obtained in the determined walking direction, the digital twin person is controlled to walk in the direction indicated by the identifier device, so as to verify whether the identifier device allocated in the real scene is valid, when it is determined that the digital twin person cannot reach an end point of the abnormal walking path under the guidance of the identifier device, and can also provide the adjustment information of the identification equipment which is not sensed by the digital twin, compared with the mode that whether the setting of the identification equipment in the places with dense people flow, such as large hubs and superstores, cannot be effectively verified in the related technology, abnormal walking paths in a real scene can be arranged in the same three-dimensional simulation environment as the real environment, and walking in the abnormal walking path by the digital twin person with different perception region ranges according to the indication of the identification device in the abnormal walking path, whether the identification equipment arranged in the real scene is effective or not is verified, and when the situation that the digital twin person cannot reach the end point position of the abnormal walking path under the guidance of the identification equipment is determined, the adjustment information of the identification equipment which is not sensed by the digital twin person can be given, therefore, the validity of the identification equipment set in the real scene can be accurately and objectively verified.
