신체 운동 능력 비교를 위한 신체 움직임 추정

초록

Recently, technologies related to human healthcare have developed increasingly. In this paper, we propose a human motion estimation method for measuring the human body physical activity. To estimate the velocity and position of body motion, a linear Kalman filter is used to estimate the attitude quaternion to remove the gravity component of accelerometer sensing value. By using acceleration value from which the gravity component has been removed, the velocity and the travel distance estimation are performed through the linear Kalman filter using the acceleration value generated by the motion. To evaluate performance of this method, front raise test has performed with attaching sensor tag on wrist. Test results show that it is possible to check the relative movement of two hands. We expects that the method proposed in this paper will be used in various convergence applications.
