This paper is aimed at describing how to measure the pitching form of baseball and suggesting measurements can be used for the quantitative sports skill evaluation. The presented measurement derived by the kinematic human body model analysis and the system developed by using the three dimensional rate gyro sensors set at the several body positions can catch the three dimensional rotation motions and the three dimensional translations of various parts of body. The system can measure the pitching forms by various players correctly. In this paper, we measure three different pitching forms, and describe the utility of the measurement and the system.
