Abstract :
The exact height measurement of a golf ball impacted in a golf simulator system is an important factor in determining the trajectory of ball. However, finding the height of a golf ball in a planar sensor using a light, poses many obstacles. In this paper, therefore, to find the height of a golf ball, the method of estimating the vertical launch angle of a ball is proposed. The flying time of a ball, while the shadow of a ball is sensed by a planar sensor, has characteristics according to the vertical launch angel of a ball. Therefore, the vertical angel is estimated from the charted data that the flying times are calculated in advance. Experimental results show that the proposed method is reasonable and practical in the golf simulator system.
