ウェアラブルフォースプレートを用いた歩行計測法の構築に関する研究

抄録

The aim of this study is to establish the gait measurement mehod using the wearable force plates. In this study, we propose the method using the Extended Kalman filter for reducing the error by acceleration integration. The gait velocity is compensated by using the condition of grounding, and the covariance matrix about process noise of Extended Kalman filter was set to coordinate with the final value of position in traveling direction. The measurement experiment was conducted by using the wearable force plates and the motion capture system, and we conducted the measurement experiment in 10m gait supposing the motion measurement of long distance. This method can estimate the gait trajectory corresponding to the final values. This method will be used to gait analysis using the wearable force plate.
