If the number of recognized marker images is less than 11, the system will automatically push a marker anomaly to the management staff to check for abnormalities such as missing marker images. The coordinates of the marker images can be manually added until all 11 coordinates in the image are obtained. The 11 obtained coordinates are sorted from the smallest to the largest horizontal coordinate to obtain the marker image coordinate set.

[0051] Among them, an identification logo image is added to the edge of each bar of the parallel ladder, and logo image images of the bar ends in various scenarios are collected and labeled. The labeled logo image images are trained using the YOLO model to obtain a logo image recognition model.

Based on the detection of the identification image coordinate set, the landing score of the target person and the starting action score of the target person are calculated according to the support point coordinates and the parameter coordinates of the target person in each frame image. Then, the terminal score of the target person is calculated based on the starting action score, the number of return criteria score, and the first number of return scores. Then, based on the terminal score and the target threshold, if it is determined that the target person has reached the terminal, the displacement score of the target person is calculated.
