Abstract(in English) | In this study, development of wearable sensor system using inertial sensors has been focused with the aim of rehabilitation support. For measurement of joint angles with this system, kalman-filtering-based angle measurement method was developed and was shown to have practical accuracy. However, there was a problem that the error was increased due to movement acceleration. In this report, the method of previous research that adjusts parameter values of kalman filter based on the values of acceleration was tested. A newly proposed method that adjusts the parameter values based on the difference between the estimated angle by kalman filter and the angle calculated from accelerometers was also tested. From the result of experiment using a rigid body model, it was suggested that the proposed method could improve measurement accuracy than the method of acceleration-based parameter adjustment. |
