System for measuring dynamic information of golf ball for screen golf

Abstract

The present invention relates to a system for measuring dynamic information of a golf ball for a screen golf, and more particularly to, such a system for measuring dynamic information of a golf ball, which accurately measures the angle and speed of a golf ball and a golf club from four different optical beam planes positioned in front of a golf ball hitting platform in a screen golf facility installed mainly in an indoor driving range so as to implement an expected carry distance and falling point of the golf ball in the form of a three-dimensional image based on the measurements of the angle and speed of the golf ball.
