METHOD OF PROCESSING PASSIVE OPTICAL MOTION CAPTURE DATA

摘要

In a method of processing passive optical motion capture data having: an image capture step fox capturing synchronized multiple camera images of a subject with passive optical markers; a three-dimensional reconstruction step for obtaining a set of three-dimensional coordinates of the markers from the picked-up data; a labeling step for deciding temporal correspondence between the markers in the subsequent captures and, thereby, locating the body part of the subject to which the markers are attached; and a joint angle calculation step for deciding an angle of each joint of a kinematic model to which the motion of subject is projected, on the basis of a set of labeled markers and computing a posture of the subject, the labeling step and the joint angle step are coupled as a loop and are performed simultaneously.
