[0044] By comparing the sliding posture of the rear skier with the different sliding posture models of turning left, going straight, and turning right stored in the storage unit, the trajectory of the skier behind relative to the wearer is estimated.
[0045] During the sliding process, the body posture of the skier changes very slowly, and the posture of the skier can be captured. After the skier changes his posture, due to the small friction between the snowboard and the contacted snow track, the direction of the skier’s sliding direction is very small. There is a certain lag between the transition and the transition of the skier's posture, so the skier's sliding trajectory can be estimated according to the skier's sliding posture.
[0046] During the sliding process, by capturing the changes in the skier's posture, the change in the skier's sliding direction can be obtained, and then the change in the direction of the skier's sliding trajectory can be obtained, so as to estima...

[0049] Such as Figure 1-Figure 4 , image 3 and Figure 4 Among them, 101 is the wearer, 102 is the second skier, 103 is the third skier, and 104 is the fourth skier.
[0050] 101 A camera device is placed on the back of the wearer's helmet or clothes to acquire a preset number of continuous images in real time, and the image deformation processing unit performs deformation processing on the acquired preset number of continuous images.
[0051] The skier detection unit detects three skiers from a preset number of consecutive images, which are respectively 102 the second skier, 103 the third skier and 104 the fourth skier.
[0052] The direction detection unit calculates the direction of the three skiers in the rear relative to the wearer 101, 102 the second skier is located directly behind the 101 wearer, 103 the third skier is located at the left rear of the 101 wearer, and the fourth skier is located at 101 the wearer's right rear.
[0053] The distance detection unit c...

[0064] Such as figure 2 , the relationship diagram of the safety distance corresponding to the moving speed of the rear skier relative to the wearer.
[0065] The horizontal axis is the moving speed of the rear skier relative to the wearer, and the vertical axis is the safety distance. Different moving speeds of the rear skier relative to the wearer correspond to different safety distances.
[0066] The moving speed of the rear skier relative to the wearer is positively related to the corresponding safety distance.
[0067] When the moving speed of the rear skier relative to the wearer is relatively large, the safety distance between the wearer and the rear skier is relatively large; when the rear skier moves relatively small relative to the wearer, the distance between the wearer and the rear skier The safety distance is relatively small; in this way, the wearer has enough time to adjust the direction and change lanes, and avoid collisions with the skiers behind him.
