MA Ya · 2001
In order to find out the way to solve the problem of fixing the positions of human body joints quickly and automatically, the method of quick calculation to fix the positions of human body joints in sports serial images was advanced. The sports information could be obtained from the sports serial images. By applying the presupposition and the contrast images of the front views of joint positions in the serial images and matching the front views and back views of the exercise joints, the exact positions of human body joints in back views were obtained. Thus, the parameters of scientific training, which the coaches are most interested in, were obtained. Many of the presuppositions and suppositions were based on the pictures taken by high speed pickup cameras or cameras. During the process of analysis, the joint positions in the first images were input artificially which are regarded as the presupposition, and the following analysis of the joint positions were done by computers. The results of the analysis were achieved quickly and accurately. Using them as the practical examples of application the parameters of the baseball and high jump technical video data were collected and analyzed.
