Developed For The Primary Users Of Video Analytic Systems

In order to solve the "high cost" and "less talent" of these two fundamental issues at the grassroots popularity and promotion of sports biomechanics in an objective reality, comprehensive analysis of the basic functions and operating characteristics of the teaching of practical needs and well-known video analytic software, based on previous research and studies of thoughts, use Adobe Flash as a development platform, developed a video capture and analysis system based on Adobe Flash Media Server (FMS) for Microsoft windows.x composition and conventional cameras, and designed a "classroom learning-after-school practice" application mode. The system is based kinesiology resolved, use "dot" way to get the screen coordinates with one by one frame or a fixed time-interval, fixed object in the environment as a reference coordinate system, it like sports facilities are known or measurable geometry, Obtained the parameters by calculating among pixel values, the shooting distance, focal distance, angle of the image pickup device and pixel values, geometry of the display, The system has a simple to use, low cost and so on. Small-scale test results show that:The results of the kinematics ordinary video resolution and frame rate by this system is consistent with the measured analytical results. Thus, the system is able to provide services, such as sports technology, body posture, tactical exercises and other aspects of qualitative real-time video capture and resolve to the primary users, in teaching and research, training and monitoring of the physical aspects of sports, and the general accuracy of the two-dimensional quantitative analysis of body posture reference data, can be used as a visual teaching, amateur training software or teaching demonstration courseware. It also can be used as teaching experiment at the University of Physical Education courses and sports biomechanics batch students hands-on practice platforms. the same time, it also be used as teaching at the University of Physical Education Sports Biomechanics course experiment platform and batch students hands-on practice platforms.
