Construction of human motion optical capture system

Abstract

With its incomparable advantages over other motion capture technologies, the application of optical motion capture systems has become more and more extensive, and it has become a major technical means for obtaining motion data. This paper mainly studies the camera calibration and 3D reconstruction technology of the optical motion capture system based on the marker, and designs an optical motion data capture system, which describes the acquisition of three-dimensional motion data, as well as the processing and analysis of motion posture feature data. By summarizing the methods and techniques of camera calibration, marker point placement, and motion drive, it effectively solves the problems of data jitter, data point loss, motion distortion, etc. generated during the motion capture process.
