METHOD AND DEVICE FOR MEASURING SPEED OF MOVING DEVICE
First Claim
1. A method for measuring a speed of a sports device, comprising:
- acquiring movement data of the sports device during a process of tracking the sports device, the movement data being collected by a sensor disposed at a bottom of the sports device;
calculating a linear speed and a rotational speed of the sports device based on accelerations of three axes in the movement data; and
combining the linear speed and the rotational speed to obtain a movement speed of the sports device.
