Abstract: The existing non rigid body three dimensional motion reconstruction algorithm is difficult to find different shapes according to different scene and different non rigid body mus, and this kind of situation will exert great influence on the reconstruction process, cause model distortion. In order to solve this problem, this paper put forward a murkowski distance based continuous non rigid body three dimensional movement recovery algorithm, which presents continuous physical characteristics on the decomposition of image sequence of frame and frame between the movement parameters and feature point displacement change. Using the physical characteristics will solve motion structure parameter in Murkowski range bound through the nonlinear optimization method, and get the non rigid body 3D motion structure, and the experiment shows that simulation verification results arc feasible.
