投球時の指によるボールの転がり操りの力学解析

抄録

The purpose of this work is to understand the mechanism of manipulating ball spin during baseball throwing. A throwing motion of arm and fingers were captured using motion capture system to understand the control of linear and rotational movement of ball. In this article we investigate how to overcome the interference of control of linear and rotational movement of it. We used singular value decomposition to identify accurate ball orientation and optimization to estimate the center of ball.
