Research on Sports Video Image Teaching System Based on Computer 3D Technology

The use of 3D technology to simulate the movement of objects, so that objects in the real environment changes. The system consists of three modules: three-dimensional simulation database, virtual simulation model of motion capture and motion technology simulation. The motion process of the backspin ball, the front spin ball and the non-spin ball is simulated numerically, and the motion law of the ball's drop point and drop point is obtained. According to different situations of players, the appropriate shooting posture is proposed. At the same time, the system uses video technology to make students familiar with NBA players, basketball tactical points, audio and other materials into a tactical demonstration of animation. The paper can effectively improve the teaching effect of basketball skill and attack training and achieve the purpose of training. The results show that the method proposed in this paper can solve the problem of turning in basketball well.
