DEVICES, SYSTEMS, AND METHODS FOR MEASURING SPIN OF A GOLF BALL

Abstract: a method for measuring spin of a golf ball includes obtaining at least two images of the golf ball after a golf club contacts the golf ball. the method also includes identifying the time span between the obtained at least two images to create a numerical time difference, defining an outline of the golf ball while the golf ball is in flight, finding at least one marking on the golf ball in each golf ball image, finding the rotations of the golf ball by aligning the at least one marking on the golf ball in each golf ball image, and converting the rotations of the golf ball into spin values by combining the rotations and the numerical time differences, wherein the spin values comprise at least a spin axis and a rotation angle. the spin values may then be displayed to a user.
