ABSTRACT With the rhythm of modern life become faster, people pay more attention to their work but ignore the importance of physical exercise. This is harmful to their health. The best way to solve this problem is to develop a “Mass Sports Teaching” system which is cheap and easy to installation. Thus people can get better instruction when they want to learn a new set of motion. Further, such a “Mass Sports Teaching” system can help to improve the whole level of their physical fitness. A complete “Mass Sports Teaching” system involves 3D human motion capture, human motion reconstruction and human motion analysis. After extensive product research and thesis review, we find that although there is such motion capture and analysis system developed for the athlete, but it is so expensive that it can not accepted by the masses. The “Mass Sports Teaching” system is still under research and there are two problems as follows: 1) Human models used in motion reconstruction are rough and regular, but the “Mass Sports Teaching” system prefers to lifelike and changeable models. 2) The current research only focuses on motion capture and reconstruction, but lack analysis of the problems occurs in motion reconstruction. According to the above problems we carry on such research as follows. First, in the aspect of 3D motion capture, to cut down the cost of the system, we choose Microsoft Kinect as our motion capture equipment which has appropriate accuracy and acceptable price. To track and record 3D human motion effectively, we adopt a rendering pipeline. First, depth data is processed in the rendering pipeline process and matches with dec
