The 3-D trajectories (X, Y, Z) of golf ball flight are captured by Hi-vision camera images. The signals of various directions and zooming of the camera are detected by the pulse signals of rotary-encoder, which mounted on camera platform. The position information of the ball on TV display is analyzed by image processing software. After integration of the information, we can get the golf ball position (X, Y, Z) in every time step t. Now, we had completed these hard wares and image processing system. Some refinements of the system are conducting on the field testing.
