Abstract

In a ball movement state measuring system with a ball, a sensing module, a wireless communication module, a power supply and an induction coil, the speed, rotation speed, rotation axis and trace of the ball at first movement state are calculated based on first accelerated speed and first angular velocity of the ball at first movement state and first movement result is obtained by the processor. The speed, rotation speed, rotation axis and trace of the ball at second movement state are calculated based on speed and rotation axis of the ball at first movement state, second accelerated speed and environment parameter of the ball at second movement state and second movement result is obtained by the processor. The ball is forced by gravity, applied force and air resistance at first movement state, and the ball is forced by gravity, air resistance and centripetal force at second movement state.
