At present, people get less and less exercise. This virtually led to a decline in the quality of people's physical. The best way to solve this problem is to develop a set of easy to install, inexpensive sports teaching system, so that people can work in a better way to get sports guidance. In view of this, this paper studied physical education teaching system, and the system has the function of 3D human motion capture, 3D human motion reconstruction and three-dimensional (3D) human motion analysis. First of all, this paper uses the Kinect platform to achieve three-dimensional human motion capture, and it focuses on the principle of 3D motion capture and technological development of 3D motion capture technology based on Kinect; Then, the motion data storage and 3D motion reconstruction of OGRE graphics rendering engine are described in this paper; Finally, this paper makes a research on the method of 3D human motion comparison, and designs the method of dynamic time warping (DTW) based on the problems existing in the actual situation, at the same time, this paper carries on the verification experiment. The experimental results show that: the three-dimensional human motion capture based on Kinect platform can meet our requirements for human motion capture accuracy. By comparison, the OGRE (Object-Oriented Graphics Rendering Engine) graphics rendering engine is more suitable to complete the rendering of the character model in the motion reconstruction. Most of the action comparison analysis method can only carry on the qualitative analysis to the movement study quality, but cannot carry on the quantitative analysis. And DTW algorithm can be a good solution to the above problems, and the physical education teaching system has high application value.
