- 論文の詳細を見る
We tested two methods of error reduction of gyroscope in measuring knee joint angle during cyclic movements. The first method was using two gyroscopes and a Kalman filter to reduce the error. In the second method, a Kalman filter was designed to estimate true joint angle by utilizing additional information from two tilt sensors. The second method reduced the error significantly. The sensor fusion with the Kalman filter would be applicable for sensing human movements in clinical measurement system or for clinical FES control.
