Abstract:
A method of measuring the motion of a golf ball, comprising the steps ofdetecting by sensor means the passing of a club head to hit a ball set at a predetermined position, wherein the ball has a mark displayed on the outer surface thereof;sending a detection signal from the sensor means to trigger means of a control unit; andin response to the detection signal, sending shutter signals from the trigger means to respective first and second CCD cameras having a shutter speed of 1/10,000 to 1/200,000 second at a proper timing, while providing an appropriate time lag between the shutter signals,photographing an image of the hit golf ball through the first and second CCD cameras, wherein the first and second CCD cameras located facing horizontally, apart from each other, and away from the set position of the ball at a predetermined distance,comparing the marks of images of the hit ball with each other which are photographed by the first and second CCD cameras and;determining a motion of at least one certain point of the mark to obtain the motion of the golf ball hit.
