Dynamic Behavior Tracking and Localization Method for Inertial Capture System
並列摘要
IMU sensors are convenient for motion tracking in daily practical applications. However, since the inertial sensors cannot provide direct location data, tracking the spatial trajectory of the person during dynamic behavior is still an open research problem. In this paper, a system and method to track the spatial dynamic behavior of human using IMUs and contact sensors are introduced. Through detecting the contact events of the feet and capturing the kinematics of the person, a tracking algorithm is used to recover the spatial trajectory of the person during dynamic motions. The measurement of the inertial system is benchmarked with the optical system, Motion Analysis. It is shown that during the jumping motion, the root trajectories match well with the optical reference. As there is no external positioning devices needed, this wearable system is very convenient to use in daily practical applications both indoor and outdoor without volume limitation.
