Abstract This paper presented a new method of elastic articulated objects (human bodies) modeling based on a new revolving conic surface. The model includes 3D object skeleton and deformable surfaces which can represent the deformation of human body surfaces. The deformation of human body surfaces can be represented by adjusting only one deformation parameter for each limb. Then, the 3D deformation and motion parameters are determined by corresponding 2D image points with volume invariable constraint from a sequences of stereo images. The algorithm presented in this paper includes motion parameter estimation of the skeleton and parameter determination of deformable surface.
