The purpose of this study was to develop the Functional golf inner-wear by preventing the injuries and enhancing the performance of the Golf swing by checking the influence of the wearing of the functional golf inner-wear considering golf characteristics on the Swing trajectory and Shot distance. Functional inner-wear effective for golf swing was manufactured using the sports taping method. Changes in driver and iron swing before and after wearing the functional golf inner-wear manufactured in this way were measured using trackman equipment. Measurement variables were limited to Club Speed, Attack Angle, Club Path, Ball Speed, Smash Factor, and Priority. Before and after wearing functional golf inner-wear, there were statistically significant differences in driver club speed, iron club speed, driver etch angle, iron club pass, driver ball speed, driver smash factor, iron smash factor, driver carry, iron carry, and right shoulder joint proprioceptive sensory ability. As a result, functional golf inner-wear is effective for ball speed, impact, and carry by increasing club speed and efficient swing. Future research will focus on the development of functional golf that can improve the swing ability in a short game that plays an important role in the golf game through various sports taping grafting technique, textile, special material, film, Research on functional golf inner-wear.

In this paper vision based system for detection of golf ball position and spin velocity in screen golf game is introduced. Firstly, an algorithm is presented for finding ball position and its initial linear velocity on the golf court, and secondly, golf ball spin is calculated. These parameters are vital for simulator in order to simulate a real golf environment. Finally, these algorithm have been implemented with acceptable result.

최근 체감형 스포츠 게임이 늘어나면서 실제 사용자의 동작을 인식하는 연구가 활발히 진행 중이다. 그 중에서도 골프에 관한 연구가 활발하다. 본 논문에서는 고속CCD카메라를 이용하여 골프공의 비행데이터를 측정한다. 고속CCD카메라는 촬영 시, 한 장의 이미지에 여러 번의 노출을 이용하여 고속으로 촬영하여 획득한 영상은 영상처리과정을 통하여 촬영된 공의 위치를 측정한다. 계산된 골프공의 위치는 물리공식을 이용하여 골프공의 비행데이터인 속도, 날아가는 방향을 계산한다. 본 시스템은 향후 비행하는 골프공뿐만 아니라, 야구, 테니스 등과 같은 타격 스포츠에서 체감형 게임 형태로 적용이 가능하다.

Golf ball spin rate after impact with club is created by the contact force, which is greatly influenced by ball and club mass, material, impact speed, and club loft angle. Previous studies showed that the contact force is determined as the resultant force of the reaction forces normal and tangential to the club face at the contact point. The normal force causes the compression and restitution of the ball, and the tangential force creates the spin. Especially, the tangential force takes either positive or negative values as the ball rolls and slides along the club face during impact. Although the positive and negative tangential forces are known to create and reduce the back spin rate, respectively, the mechanism of ball spin creation has not yet been discussed in detail. It is shown in this work that the linear impulse of the tangential force is directly related to generation of back spin rate of golf ball. The linear impulse can be calculated from the tangential force, which depends upon many factors such as ball and club mass, material, impact speed, and club loft angle. In this research, the influence of the contact force between golf club and ball is investigated to analyze the mechanism of impact. For this purpose, the contact force and the contact time at impact between golf club head and ball are computed using FEM.

In this study, we propose a pseudo golf club which can sense user's swing motion and virtual golf simulation system using the pseudo golf club. The proposed system is a virtual golf simulation system of a complex play type in which a player can enjoy various types of golf play according to the user's taste by providing a play mode for hitting an actual golf ball and a play mode for swinging the pseudo golf club. This virtual golf play system calculates and displays the trajectory of a golf ball by a simulator just like playing a real golf, and suggests suitable swing motion, so it helps users to learn golf easily.

본 논문에서는 골프 퍼팅연습 시 사용자의 편의를 도모하기 위해 고속카메라를 이용한 골프공 추적방법을 제안한다. 이것은 요즘 많은 사람들이 즐기는 레저스포츠 중 골프 퍼팅부분을 정확하게 칠 수 있도록 분석하기 위한 것이다. 제안방법은 일반 USB카메라를 사용할 경우 화소들이 뭉게져서 골프공 검출률이 낮으므로 최대 초당 380프레임까지 측정이 가능한 고속카메라를 사용하였다. 먼저 전처리 후 허프변환을 이용하여 골프공을 검출한다. 그 후 검출된 골프공의 정보를 이용하여 이동경로, 이동거리와 각도를 구한다. 제안한 방법을 적용한 결과 골프공의 검출률이 향상되었고 이동경로, 이동거리와 각도의 정확성도 향상되었다.

Robot has been developed as something to help human beings, and robot will be very important field as an entertainment. This paper intends to contribute to developing golf robot as an entertainment using AVR ATmega Chips. It is believed that the entertaining robot giving a pleasure to human beings has good prospects for the rapid growth along with other robot industry. Golf robot developed in this paper has been developed for entertainment and has a similar sense in comparison with the real golf. This golf robot is represented in the way of putting the ball in the hall by hitting the ball just like the actual golf game and putting through making robot come close to the ball with the putting robot. This golf robot can playa game with several people like the actual golf if many putting robots can be used. It is, therefore, considered that the development of golf robots for entertainment using AVR has a high value of the golf robot as an entertainer on the ground that it can playa real golf.

PURPOSE: To determine the effect of weight ball throw training as a preparatory exercise before golf practice for 8 weeks on back muscle strength, weight shifting of lower body, head speed of club, and driving distance of amateur golfers. METHODS: A total of 18 subjects were randomly assigned to the experimental group (n=9) and the control group (n=9), respectively. For the experimental group, Weight ball throw training was provided to the height of waist and shoulder similar to golf swing with the following schedule: 3 kg weight ball throw training from the first week to the 4th week; 5 kg weight ball throw training from the 5th week to the 8th week. Before and after 8 weeks of training, back muscle strength, weight shifting of lower body, head speed of club, and driving distance of subjects in the two groups were measured. RESULTS: The experimental group showed significant differences in rotational back extension torque, weight shifting of lower body, head speed of club, and driving distance during golf swing (p<.05). However, the control group only showed significant difference in driving distance during golf swing (p<.05). Back extension torque, weight shifting of lower body, and head speed of club showed significant differences between the two groups during golf swing (p<.05). CONCLUSION: Weight ball throw training can positively change rotational back muscle strength, weight shifting of lower body, head speed of club, and driving distance of amateur golfers. Therefore, it might be used as an effective warming up exercise for amateur golfers.
