Human body tracking method and system

The invention relates to the technical field of human body tracking and discloses a human body tracking method. Different human body tracking precision can be selected according to needs, an optical tracking module is responsible for human body tracking with low precision, an electromagnetic tracking module, an acoustic tracking module and a motion sensor cooperate to perform human body tracking with high precision, and the purpose of improving the measurement precision is achieved. 本发明涉及人体跟踪技术领域，公开了一种人体跟踪方法，可根据需要选择不同的人体跟踪精度，光学跟踪模块负责较低精度的人体跟踪，由电磁跟踪模块和声学跟踪模块以及运动传感器协同进行较高精度的人体跟踪，达到提升测量精度的目的。
