Abstract
The present application discloses a top-mounted golf ball detection method, applied to a golf system with a top camera configured for detecting a golf ball provided with a mark thereon. The method comprises: calibrating a camera: converting an image coordinate system of the camera into a world coordinate system; positioning a golf ball: acquiring coordinate data of the golf ball by performing a global positioning on an entire first frame picture captured by the camera after the ball is served; and for a subsequent frame picture captured by the camera after the ball is served, predicting a falling point range of the golf ball and obtaining a local picture of the frame picture according to the falling point range, and acquiring coordinate data of the golf ball by performing a global positioning on the local picture; calculating parameters; and detecting a rotating speed of the golf ball.
