XU Cheng, HE Jie, ZHANG Xiao-tong, et al. Human Motion Tracking Performance Evaluation Method Based on IMU/TOA Fusion[J]. Acta Electronica Sinica, 2019, 47(8): 1748-1754.
With the rapid development of the Internet of things and the body area network
the human motion tracking technology has been widely used in medical
security and many other fields. A human motion tracking method based on IMU/TOA fusion is proposed to solve the problem of error accumulation and drift in a single IMU human motion tracking system. On this basis
the effectiveness of IMU/TOA fusion method is proved theoretically by deducing the cramer-rao lower bound (CRLB) of fusion system. The experimental results show that the proposed human motion tracking method based on IMU/TOA fusion has great improvement in both spatial and temporal performance.
