Abstract

UWB signals are widely used in indoor precise positioning due to their good temporal resolution. Motion capture can be realized by tracking human joints in 3d space with the precise positioning characteristics of the UWB system. Compared to traditional motion capture technology, UWB technology has advantages in cost and system complexity. This paper reviews existing research of the motion capture based on UWB technology, and analyzes the design of the whole body motion capture system based on UWB technology from three aspects of the algorithm, application scenarios and technical difficulties. The research proves that UWB technology can be used as a substitute for the existing motion capture technology and has certain competitiveness. However, the research on motion capture system based entirely on UWB technology is still limited to studying individual limbs of human body. Therefore, the large-scale application of UWB system for motion capture under complex indoor conditions still needs further research.
