Abstract
The present application discloses a golf ball floor type detection method, a system, and a storage medium. The method includes the following steps: correcting distortion of the camera; calibrating a camera; triggering of hitting a ball: monitoring a pixel variation value of a serving position of a golf ball in a picture captured by the camera in real time, and determining triggering of hitting a ball when the pixel variation value of the position exceeds a threshold value; positioning a golf ball: processing the picture captured by the camera after triggering of hitting a ball with a dynamic segmentation based on a fuzzy entropy, and positioning the processed picture to acquire coordinate data of the golf ball; calculating parameters; and detecting a rotating speed of the golf ball.
