Patent attributes
A golf simulation system includes a processor configured to receive image data from a launch area sensing unit to determine position, velocity, acceleration and spin of a golf ball and to calculate a trajectory of the golf ball into a golf scene presented on a display surface. The system includes a processor that generates a profile of a golf ball travel path over a plurality of images, determines the golf ball travel path length per image of the plurality of images, identifies regions corresponding to one or more markings on the golf ball, determines the distance between the regions in each image, calculates the spin rate and tilt of the golf ball using the determined distance, and uses the golf ball travel path length and camera device frame rate to estimate a spin tilt axis of the golf ball using the orientation of the regions in each image and the relative angle between the longitudinal axis of the regions and the longitudinal axis of the golf ball travel path.
