Local and Global Skeleton Fitting Techniques for Optical Motion Capture

摘要

Identifying a precise anatomic skeleton is important in order to ensure high quality motion capture. In this paper we discuss two skeleton fitting techniques based on 3D optical marker data. First a local technique is proposed based on relative marker trajectories. Then it is compared to a global optimization of a skeleton model. Various proposals are made to handle the skin deformation problem. Index Terms-skeleton fitting, motion capture, optical markers.
