Research on Theory and Practice of the Construction of Real-time Automatic Analysis System of Tennis Techniques and Tactics

Objective: The development and research of the system will lay a foundation on the theory and method of automation management of the technology of tennis athletes in our country and provide data support for the reasonable training, utilization of techniques and tactics in competition and strategy customizing for different sports teams and athletes, so as to make science and technology assist competitive sports, which is of great significance on improving the tennis technology level of our country. Method: On the basis of principle and knowledge in sports dynamics, documentation, comparison analysis method and logic seasoning method are used in the thesis; successive video shot by two cameras is used to catch the dynamic target in the scene on a real-time basis. It is mainly used for the track description of the three-dimensional sports trace, three-dimensional projection drawing and other relevant parameter of the ball and athletes in competition, so as to construct the automatic analysis system of tennis techniques and tactics. Result: The following technical links must be resolved in order to establish automatic analysis system of techniques and tactics: path to realize the construction of real-time analysis system of techniques and tactics in tennis; technical integration in the practice application of real-time analysis system of techniques and tactics in tennis sports; validity enhancement of practice application of real-time analysis system in techniques and tactics of tennis sports. Conclusion: The feasibility of the real-time automatic analysis system of tennis techniques and tactics is studied from the theory of system research and data collection, program operation, implementation path and validity of the system are demonstrated in detail, so as to provide some theoretical support for the tennis analysis software technology researched and developed by our county independently and make the competitive tennis training of our country more scientific and practical.
