Abstract:
1. A method of processing images of a golf ball having reflective markers comprising the steps of: providing first and second cameras; capturing a first pair of images of the golf ball with the first camera; capturing a second pair of images of the golf ball with the second camera; dividing the first and second pair of images into a plurality of pixels; assigning a color to each pixel, the assigned color being either a first color if the pixel has a brightness above a predetermined threshold level or a second color if the pixel has a brightness below the predetermined threshold level; connecting adjacent pixels of the first color to form bright areas; corresponding the bright areas to identify the reflective markers on the golf ball; calculating the location of the reflective markers by comparing the first pair of images with the second pair of images; and determining at least one of the transverse velocity and spin rate of the golf ball.
