Simulation system for golf practice

Abstract

In a golf simulation system, a setting plate for locating a golf ball is provided in a striking zone, and a setting plate adjusting means is provided below the setting plate. A control section calculates moved distance and stoppage position of golf ball based on the flying trace of golf ball sensed by the flying trace sensing means, and inputs signals reflecting the three-dimensional images of the golf course along the flying trace into the projector, so that the three-dimensional images are displayed on the projection screen. Also, the control section controls the setting plate adjusting means in accordance with the height and inclined angle of the stoppage position, so that the setting plate can be automatically adjusted to the height and inclined angle equal to those of the stoppage position. Therefore, a golfer can exercise golf in various inclined angles and topographical conditions like a real golf course.
