The Applied Research Of The Video Feedback System For The Analysis And Diagnosis Of The Technical Movements Of Wushu

With the development and innovation of Competitive WuShu, the main purpose is to gradually close to the Olympic skill dominated categories of projects. Since Competitive WuShu have added difficulty elements, made the competition even more fierce, usually, A score of 0.01 will be able to determine the success of the game. Therefore, the provinces and municipalities pay more attention to the WuShu Team of IT services to ensure the coaches and athletes can get more training in quantitative indicators of technical movements. In this study, motion analysis system (Dartfish) used for the Shanghai team for the Eleventh National Games to provide routine technical movements of the technology services, and to explore the applications in WuShu training and competition with the main technical tools of video feedback. Its findings are as follows:(1).Own technical movements Contrast:Through analyze the successful completion motion video images and the mistakes video interface in the same comparison of the same individual and find shortcomings in its technical movements.(2). Technical movements compared with rivals:A study by an individual with another individual the same research projects and combined action of the image on the same video interface, a comparative study of different individuals in order to discover the completion of the same technical movement when existence of differences.(3).Multi-angle observation:motion analysis system can receive two or more of the camera image signal coming through at the same video interface in the field at the same time,observed from different angles to complete the same degree of difficulty of movements.(4).The disconnect of the action:By motion analysis system, an action can be decomposed into a number of successive transition moves to help coaches, athletes, technical movements observed specific changes in various aspects of the situation in order to assist in the guidance of an effective evaluation of coaches.(5).On the action of local amplification:By this motion analysis system, the part of local amplification of technical movements can be observed more clearly and more easily to help coaches and athletes analyze problems and solve the problem.(6). Angle measurement and time measurement:Through the angle measurement and time measure by this motion analysis system, you can get a more objective assessment for the movement complete.For example, the set of time measurement of class actions of balance and the connection point of the measured floor action.Main conclusion:Dartfish motion analysis system can achieve the goal in the same video interface and individual's own same actions of the former and the latter, the same items of the action. Motion in different individuals,the same comparison and analysis system can be difficult to move the multi-perspective and observe the movements of the decomposition of functions, athletes can be more objectively reflect the real situation is improved and perfected the technical movement.The use of motion analysis system, the calculation of time, partial zoom, angle calculation function, WuShu movements can balance the set of time estimates, balanced position of buckle legs, the difficulty of the landing angle connect action, etc.A simple calculation, and video feedback, the coaches and athletes can be more effective obtain feedback.in the short term...
