For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
A tested person can contact with the ground or finish actions in the air during running, and the exercise technology, the human body mechanics and the physical mechanics of the tested person are greatly involved. From the moment that the runner touches the ground, the motion state of the runner can be analyzed and studied from the acceleration and the angle of the three axes of X (front and back of the running direction of the person), Y (left and right of the person) and Z (up and down of the person). The acceleration in the front-rear direction, the acceleration in the left-right direction, and the acceleration in the up-down direction are included. The braking force, stability, physical performance characteristics, physical change paths and the like generated when the vehicle falls on the ground can be analyzed, and further conclusion can be drawn according to the actual results and trend analysis.
The running motion is analyzed by adopting an acceleration sensor, and the acceleration and the angle are acquired by the sensor. The subject only needs to place the sensor at the ankle of the wearer, thereby collecting all acceleration and angle data from start to complete stop, and no other measuring equipment is needed.
The running exercise is divided into 3 phases and 6 actions, wherein the 3 phases are specifically a starting phase, an intermediate running phase and a braking phase (a phase of decelerating to a complete stopping), the 6 actions of the intermediate running phase are ground contact (grounding), buffering, back pedaling, back swinging, front swinging and pressing, as shown in fig. 1, the 6 actions form a complete step, and the running is to continuously repeat the 6 actions.
The scheme is to identify the 3 stages according to the collected sensor data, then further identify the 6 actions of each step in the in-transit running stage, and further analyze the type of each action.
In one embodiment, as shown in fig. 2, a method for determining a type of backswing is provided, comprising the steps of:
step S201, obtaining movement data of a target object in the running process, and extracting an angle characteristic value and a change trend characteristic value in the movement data.
The target object may be any living body capable of realizing the running exercise, wherein the running exercise may be divided into 3 phases and 6 actions, the 3 phases are specifically a starting running phase, an intermediate running phase and a braking phase (a phase of decelerating to completely stop), and the 6 actions of the intermediate running phase are ground contact (grounding), buffering, back pedaling, back swinging, front swinging and pressing.
The exercise data refers to data collected by a sensor provided on the object during running exercise of the object, such as starting phase data, intermediate running phase data, braking phase data (phase of decelerating to complete stop) or ground contact (landing) data in 6 actions of the intermediate running phase, buffer data, back-pedaling data, back-swinging data, front-swinging data, pressing data, and the like.
After the motion data is obtained by the sensor, the motion data is analyzed to extract data corresponding to the backswing motion, such as the speed, the acceleration and the like of the backswing motion. In the process of judging the type of the backswing, only the angle characteristic value and the change trend characteristic value are extracted to further judge the type of the backswing action.
Step S202, determining the characteristic value frame number of the backswing point based on the angle characteristic value and the change trend characteristic value.
And determining the characteristic value frame number of the backswing point based on the angle characteristic value and the change trend characteristic value, wherein the angle characteristic value and the change trend characteristic value are required to be judged, and specifically, if the angle characteristic value is not equal to the change trend characteristic value, the last point of the trend stable section is taken as the characteristic value frame number of the backswing point.
And step S203, determining the type of the backward swing according to the characteristic value frame number of the backward swing point.
For the determination of the type of the backswing, the following two main approaches are adopted:
In the first case, the backswing initiative feature value corresponding to the feature value frame number of the backswing point is required to be acquired, and then the backswing action type is determined based on the backswing initiative feature value, the x-axis acceleration feature judgment value and the z-axis acceleration feature judgment value.
Illustratively, the determining the backswing type based on the backswing initiative feature value, the x-axis acceleration feature determination value, and the z-axis acceleration feature determination value requires determining an extremum of the z-axis acceleration feature determination value based on the x-axis acceleration feature determination value and the z-axis acceleration feature determination value, and then determining the backswing type based on the extremum of the z-axis acceleration feature determination value and the backswing initiative feature value.
And judging the extreme value of the z-axis acceleration characteristic judging value through a preset threshold value, specifically, if the x-axis acceleration characteristic judging value is larger than a first preset threshold value, reading the z-axis acceleration characteristic judging value, and if the number of the z-axis acceleration characteristic judging values is larger than a second preset threshold value, obtaining the extreme value of the z-axis acceleration characteristic judging value. After the extreme value of the z-axis acceleration characteristic judgment value is obtained, the extreme value based on the z-axis acceleration characteristic judgment value and the backswing initiative characteristic value are needed, and the backswing action type is determined, namely, if the extreme value of the z-axis acceleration characteristic judgment value is larger than the backswing initiative characteristic value, the backswing action type is active backswing, and if the extreme value of the z-axis acceleration characteristic judgment value is smaller than or equal to the backswing initiative characteristic value, the backswing action type is passive backswing.
In the second case, only the angle change characteristic value within the preset range of the characteristic value frame number of the back swing point is compared with the swing characteristic value, so that the back swing operation type is determined. Specifically, if the angle change characteristic value of the back swing point in the preset range of the characteristic value frame number is larger than the swing characteristic value, the back swing is a folding back swing, and if the angle change characteristic value of the back swing point in the preset range of the characteristic value frame number is smaller than or equal to the swing characteristic value, the back swing is a non-folding back swing.
The embodiment of the invention provides a method for determining a backswing action type, which comprises the steps of obtaining motion data of a target object in a running process, extracting an angle characteristic value and a change trend characteristic value in the motion data, determining a characteristic value frame number of a backswing point based on the angle characteristic value and the change trend characteristic value, and determining the backswing action type according to the characteristic value frame number of the backswing point. According to the invention, the angle characteristic value and the change trend characteristic value of the target object in the running process are extracted, and then the characteristic value frame number of the backswing point is further determined through the angle characteristic value and the change trend characteristic value, so that the backswing type is determined based on the characteristic value frame number of the backswing point, the problem of low efficiency in an image comparison mode is avoided, and the accuracy of the backswing type judgment is improved.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
