POSTURE ACQUISITION METHOD AND DEVICE, AND KEY POINT COORDINATE POSITIONING MODEL TRAINING METHOD AND DEVICE

摘要

A posture acquisition method and device, and a key point coordinate positioning model training method and device. The posture acquisition method comprises: acquiring a target video (201); with regard to an ith image frame in the target video, acquiring a heat map of the ith image frame, i being a positive integer (202); according to the heat map of the ith image frame and the heat map of the adjacent image frame of the ith image frame, obtaining the three-dimensional coordinates of a key point in the ith image frame (203); and according to the three-dimensional coordinates of the key point in the ith image frame, acquiring a target posture of a target object in the ith image frame (204). Said method effectively overcomes the problem of inaccurate prediction caused by different sizes and postures of a target object in different pictures, thereby improving the accuracy of the predicted key point position, and further improving the accuracy of the acquired posture.
