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.
Description
- The present invention relates to a golf simulation system; and, more particularly, to a sensing system for an entering angle, a space velocity and a hitting point, which can sense a shadow of a club head when a user practices a golf swing in a golf simulation system and obtain an entering angle, a space velocity and a hitting point of the club head.
- Generally, an indoor golf practice range is a place for practicing a golf swing in order to make a player proficient in golf.
- However, since the indoor golf practice range has different atmosphere and environment from an actual outdoor golf course, there is large difference between the indoor golf practice range and the outdoor golf course, and also as compared with the practice in the indoor golf practice range, it is difficult to obtain the desired result in the actual outdoor golf course.
- To solve the above problems, there has been proposed a golf simulation system in which an environment similar to that in an actual outdoor golf course is provided at an indoor golf practice range so as to obtain an effect of hitting or putting a golf ball in the actual outdoor golf course.
- As shown in
FIG. 1 , the golf simulation system includes amain computer 110 which executes a golf simulation program for providing an environment similar to an actual outdoor golf course, aprojector 120 which is connected with themain computer 110 so as to project a virtual image corresponding to the environment in the actual outdoor golf course, ascreen 130 which displays the virtual image projected from theprojector 120, a sensing system which has a plurality of sensors for detecting a movement velocity, direction and trajectory of a club head, and a direction, velocity and launch angle of a ball when a golf practicer hits the ball, and acamera 150 which takes a picture of a swing motion of the golf practicer when hitting or putting the ball and then provides the pictures to the golf practicer. - In an operation of the golf simulation system as described above, the golf practicer chooses a golf club for hitting the ball and then hits or putts toward a screen the ball supplied by a ball supplying unit.
- When the golf practicer hits or putts the ball, a sensing part having a plurality of optical sensors detects the club head swung by the golf practicer and the ball flown by the hitting, analyzes a swing result and then projects the ball on the screen connected with the main computer.
- However, since the conventional golf simulation system as described above measures only the velocity, direction and launch angle of the ball flown by the hitting and calculates a flying trajectory of the ball, the flying trajectory of the ball may be partially inaccurate.
- In case of a system of analyzing golf ball and head information using a laser and a four-axial optical sensor, in order to complement the above-mentioned problem, a trajectory of the club head is obtained by using the velocity, direction and launch angle of the ball and a sensing system that is proposed by the applicant and installed at a bottom surface, and then it is determined whether the trajectory of the club head is OutSide-InSide, InSide-InSide or InSide-OutSide, thereby increasing accuracy of the flying trajectory of the golf ball.
- However, there is also a problem that it is not possible to directly measure a back spin of the ball. In other words, since the back spin is obtained by just reflecting the launch angle, the accuracy of the flying trajectory of the golf ball is deteriorated.
- Further, in view of the fact that every golf practicer has to swing with optimal entering angle and velocity for each club in order to achieve an accurate swing, information of the entering angle and velocity of the club head is very important to the golf swing analysis. However, since the sensor cannot the information, the accuracy is deteriorated.

parts - Herein, the shadow of the club head is generated by a light source positioned at an upper side of the first, second and third bottom sensing
parts - If each of the first, second and third bottom sensing
parts bottom sensing parts bottom sensing parts - And the trajectory and velocity of the club head with respect to the bottom surface is obtained by using the shadow information of the club head detected by the first, second and third
bottom sensing parts - Further, it can be also determined whether the trajectory of the club head passing through the first, second and third bottom sensing
parts - Meanwhile, the vertical sensing
part 204 which is inclinedlyinclinedlyvertically disposed with respect to a vertical surface receives the light from thelaser 250 positioned at a rear side of thevertical sensing part 204, detects the shadow generated when the club head is passed through thelaser surface 251, and then analyzes the golf ball and the club head using the detected shadow information. - The launch angle and space velocity of the golf ball can be measured by using the shadow information of the golf ball and the club head detected by the
vertical sensing part 204, thereby improving the accuracy of the driving distance and the accuracy of flaying simulation of the golf ball. - As described above, the plurality of bottom sensing
