Sensing system for entering angle and space velocity and hitting point

Abstract

A sensing system for providing an entering angle, a space velocity and a hitting point to a golf simulation system is provided, in which a club head sensing part and a horizontal sensing part horizontal with a bottom surface are disposed at a position that the club head swung by a golf practicer is entered, so as to sense shadow information of the club head, thereby obtaining the entering angle, the space velocity and the hitting point of the club head.

1 . A sensing system for an entering angle, a space velocity and a hitting point, that comprises a bottom sensing part having first, second and third bottom sensing parts which are disposed to be spaced apart at regular intervals in a length direction of a bottom surface and in which a plurality of optical sensors are arranged straight in a width direction so as to receive light from a light source and sense a shadow of a golf ball and a club head; a vertical sensing part which is inclinedly inclinedly disposed at one side of the third bottom sensing part of the bottom sensing part in a vertical direction so as to sense the shadow of the golf ball and the club head passing through a laser surface formed by receiving laser from a vertical layerlaser emitting unit opposed to the vertical sensing part; and a controlling part for obtaining position coordinates of the golf ball in a space using shadow information of the golf ball and the club head sensed by the bottom sensing part and the vertical sensing part, comprising:
 an entering sensing part which is vertically disposed at one side of the first bottom sensing part  11  that the club head swung by a golf practicer is entered, and also which is inclined to be symmetrical with the vertical sensing part; and   a horizontal sensing part which is disposed at a lower side of the entering sensing part to be horizontal with the bottom surface of a swing plate,   wherein the controlling part obtains the entering angle of the club head using the shadow information of the club head sensed by the entering sensing part and the horizontal sensing part, and also obtains the hitting point of the club head using the shadow information of the club head sensed by the horizontal sensing part.   
     
     
         2 . The sensing system of  claim 1 , wherein the entering sensing part receiuves laser from a layerlaser emitting unit opposed to the entering sensing part so as to sense a shadow of the club head passing through a laser surface formed between the layerlaser emitting unit and the entering sensing part. 
     
     
         3 . The sensing system of  claim 1 , wherein the horizontal sensing part receives laser from a layerlaser emitting unit opposed to the horizontal sensing part so as to sense a shadow of the club head passing through a laser surface formed between the layerlaser emitting unit  90   b  and the horizontal sensing part.
