Application of modern science and technology gradually goes deeply in sports that gives rely to the development of mass sports and competitive sports, and high technology has already become great motive force to modern sports development. Free basic spinning motion is indispensable key motion in rhythmic gymnastics that influence such sports results. In order to objective precise reproduce and analysis spinning process, modern computer vision system can provide more convenient way for it. This paper based on modern computer vision system, carries out analysis of five white small ball mark points spacious location situation following human sports that well designed in rhythmic gymnasts so as to explore gymnasts upper body each segments kinematics features through relationships between adjacent frames, and provide theoretical basis to gymnastics perfect development and scientific guides.
