[0041] Step 1. Video frame image preprocessing. For the source video data, first of all, the frequency of taking one frame every 25 frames is used to collect image frames. For the video that needs to be used in the training phase, each time a continuous T frame is randomly selected from the collected video frames as the input data of the network. For the video that needs to be used in the test phase, each time the middle T frame is taken from the collected video as the input data of the network. T takes 16. The resulting video clips are Indicates that I t Indicates the tth image frame.
[0042] Step 2. Obtain the location area of the actor in the image. For each selected video frame image I t , input it into the existing openpose network structure (article [9]), predict the corresponding human bone joint points, and then determine the position area of the actor according to the position coordinates of the joint points to help the initial human body reconstruction T...
