This paper proposes the measurement method of 3D posture using inertial sensors. The proposed method estimates the 3D posture (Roll-Pitch-Yaw angles in local coordinate) using the 3-axis angular velocity and the 3-axis acceleration. The 3D posture is compensated for the drift error of gyro sensor output by the translational and gravity accelerations of accelerometer output. The nonlinear state equation and the nonlinear measurement equation were established to estimate 3D posture. The Extended Kalman filter and the Unscented Kalman filter are applied to these equations. The measurement experiment was conducted to clarify the accuracy of proposed method using the experimental setup installing the rotary encoders. The results of the Unscented Kalman filter indicated higher than those by the Extended Kalman filter. In addition, the proposed method estimated the 3D posture compensating the drift error of gyro sensor in the measurement experiment generating the translational acceleration. Therefore, the proposed method can be used for the measurement of body motion.

&nbsp;&nbsp;&nbsp;&nbsp;This paper proposes a measurement system and computation method for 3D motion analysis in sports. The measurement system that consists of inertial and magnetic field sensors is able to measure 3-axis angular velocity, 3-axis acceleration and 3-axis magnetic field. We can easily perform the experiment in sports because this system is directly attached to the body. Introducing the sensor fusion algorithm using Kalman filter, we can avoid storage error by the drift of the gyro sensor. The computation method provides the angles by compensation of centrifugal and tangential acceleration and sensor fusion. <BR>&nbsp;&nbsp;&nbsp;&nbsp;In order to confirm the accuracy of this proposed system and computation method, we compared the value obtained by this system with the value obtained by a rotary encoder. It was found that the measurement system and computation method provided the accurate value. It is shown that the proposed method can be used for motion analysis in sports.

This paper describes a new method to measure and analyze three-dimensional rotation and translation analysis of upper limb in basketball shot form. In general, the shot form is measured by taking the photograph of motion with the high-speed camera and/or video camera and analyzing the photograph with direct linear transformation method (DLT method). The suggesting measurement method was derived by the kinematic human body model analysis. The measurement system developed by using the three dimensional rate gyro sensors set at the several body positions can measure the three dimensional rotations and the three dimensional translations of various parts of body. By using this system, the motion of a thin part such as wrists and ankles can be measured easily. In addition, this system can measure the basketball shot forms of various players correctly.
