Volleyball Movement Trajectory Analysis Based on Three-Dimensional Visual Tracking

Abstract:

in volleyball movement process, there is greater uncertainty in velocity and position of movement. Using traditional algorithms for volleyball movement trajectory analysis, it cannot get changes situation of volleyball movement trajectory, resulting in that there is a big deviation in volleyball movement trajectory analysis, and the accuracy of analysis is decreased. To this end, this paper proposes a volleyball movement trajectory analysis method based on scale dynamic transform analysis algorithm. According to the related theory of attenuation memory, the key frame image in the process of volleyball movement is extracted, thus providing a basis for volleyball movement trajectory analysis. Utilizing scale dynamic transform method, the background of volleyball key frame image is separated, to obtain the volleyball movement trajectory in current frame image, so as to achieve volleyball movement trajectory analysis. Experimental results show that using the proposed algorithm for volleyball movement trajectory analysis can effectively increase the accuracy of volleyball movement trajectory analysis, and achieve satisfactory results.
