It analyzes human movement behaviors with systematic conceptions, and studies technical movements of athletes through input-output relationship of human movement behaviors. Through fuzzy mathematics, mathematical statistics and artificial intelligence, integrating and drawing reference from sport biomechanics, graphics, human anatomy and expert system etc., the system solves a series of key problems both in theory and application from information extraction, inference to multi-objective parameter fusion and decision-making, and then designs and develops biomechanical evaluation system for shot sport technology. Considering the multiple events that the sport contains, the research primarily proceeds from shot, and establishes "coach-athlete" expert evaluation system. 收起
