拡張カルマンフィルタを用いたスポーツにおける角速度・角加速度計測

抄録

The measurement of angular velocity and angular acceleration in sports biomechanics is usually based on cinematography. But this method dose not have good accuracy. Authors previously developed angular velocity and angular acceleration measurement system, which used 12 accelerometers. But this system is tedious, beacause of mounting the large number of accelerometers.
This paper proposes a measurement system using 9 accelerometers in sports, which accurately measures the rotation motion. This measurement system uses the extended Kalman filter. The accuracy of this method was examined by simulation and experiments.
