Classification: CPC G | IPC G

Claim 8:
9. A golf ball tracking system, comprising:
a camera configured to capture a plurality of image frames of a golf surface;
a memory configured to store the plurality of image frames;
a processor configured to:
identify at least a first pixel at which a golf ball is located in a first image frame of the plurality of image frames;
identify at least a second pixel at which the golf ball is located in a second image frame of the plurality of image frames;
determine that the first pixel represents a location where the golf ball impacts the golf surface based at least in part on a difference in location between the first pixel in the first image frame and the second pixel in the second image frame;
identify at least a third pixel corresponding to at least a first calibration marker in the first image frame; and

determine at least one of a location and a distance of the golf ball with respect to a reference point based at least in part on the location of the first pixel and the location of the at least third pixel in the first image frame;
wherein the processor is configured to determine that the first pixel represents the location where the golf ball impacts the golf surface by:
determining that a first difference in location between the first pixel in the first image frame and the second pixel in the second image frame is smaller than a second difference in location between a pixel at which the golf ball is located in an image frame of the plurality of image frames captured immediately prior to the first image frame and the first pixel in the first image frame.
