The aim of this study is to propose the measurement method of three-dimensional (3D) movement of forearm and upper arm during pitching motion of baseball using inertial sensors without serious consideration of sensor installation. Although high accuracy measurement of sports motion is achieved by optical motion capture system at present, it has some disadvantages such as the calibration of cameras. Whereas the proposed method for 3D measurement of pitching motion using body mounted sensors provides trajectory and angle of forearm and upper arm by the integration of acceleration and angular velocity measured on upper limb. The experimental results show that 3D location of shoulder, elbow and wrist estimated by the proposed method corresponds to that measured by the optical motion capture system.
