Data Compensation Based On The Additional Feature Information For Collaborative Interactive Operation With Optical Human Motion Capture System

As the effective capture region of optical motion capture system is limited by quantity, installation mode, resolution and focus of infrared cameras, the reflective markers on certain body parts (such as wrists, elbows, etc.) of multi-actual trainees may be obscured when they perform the collaborative interactive operation. To address this issue, motion data compensation method based on the additional feature information provided by the electromagnetic spatial position tracking equipment is proposed in this paper. The main working principle and detailed realization process of the proposed method are introduced step by step, and the practical implementation is presented to illustrate its validity and efficiency. The results show that the missing capture data and motion information of relevant obscured markers on arms can be retrieved with the proposed method, which can avoid the simulation motions of corresponding virtual operators being interrupted and deformed during the collaborative interactive operation process performed by multi-actual trainees with optical human motion capture system in a limited capture range.
