A Pose-Independent Method of Animating Scanned Human Bodies

With the development of 3D scanning technique, animating scanned human body model becomes one of the most active research fields in virtual human modeling. Most of the existing methods have difficulty in animating scanned human body models with arbitrary poses automatically. In this paper, a new framework for pose- independent animating scanned human body is presented. Firstly, feature points and topological structure of the model can be extracted automatically according to Morse function which is based on geodesic distance of human body model and then the body is divided into segments. Secondly, joints can be calculated by analyzing the circularity function of geodesic isolines of the model. Thirdly, vertexes of human body models are mapped to the skeleton and the deformation weights of the vertexes are calculated. The experiments demonstrate that our approach is pose-independent, robust and automatic.
