Abstract: Interactive method is raised in this paper to abstract three dimension human motion data from video by combining human distinguishing and computer graphics simulation. The approach to abstract human three dimension data is a whole posture, not a single joint, and which is different from the manual approach. A series of experiments are taken to test human distinguishing which is the key in the interactive method. Graphic, photo and video are used as samples in the experiment. The result shows that human distinguish posture well. In the bottom of this paper, the procedure of data processing is introduced that how to compute velocity and acceleration of each joint angle and each limbs.
