Abstract
In the passive optical motion capture system, occlusion caused by the hidden markers occurs between whiles. A method based on least square for detecting and estimating of such lost points is proposed in this paper. First, we give an algorithm to find the abnormal markers by detecting the extra large derivatives of the markers´ trajectories. Second, two models for estimating the abnormal markers, the rigid one and the linear transformation one, are discussed. The results of the experiments shows the validity of our method.
