4 is a view showing a photographing region of a golf club and a golf ball according to an embodiment of the present invention. 4, the high-speed video cameras 220 and 230 capture an initial position 30 where a golf ball is placed, an area where the golf ball passes before hitting the golf ball, and an area where the golf ball is flying after the golf ball is hit Can be installed. An imaging area including an initial position 30 where a golf ball is placed, an area where a golf club passes, and an area where a golf ball is flying can be defined as a total photographing area 10 of the high speed image cameras 220 and 230. The area where the golf club passes can be defined as the golf club shooting area 20 and the area where the golf ball is flying can be defined as the golf ball shooting area 40. [ The golf club photographing area 20 may define a progressive direction of the golf club so that the golf club can be photographed, and the photographing area 40 of the golf ball may include a golf ball progressing direction 50, Can be defined as a shooting region.

The high-speed video cameras 220 and 230 can photograph the golf club shooting area 20 more than once in the golf club shooting area 20. [ The golf club shooting area 20 may be an area of a predetermined proceeding direction of the golf club facing the golf ball in a stopped state. The present invention sets the area of the planned traveling direction of the golf club facing the golf ball in the stopped state to the golf club shooting area 20 so that the golf club can be photographed without missing.

Of the camera image sensors used in the currently-marketed high-speed video cameras 220 and 230, a small shooting region can be designated within the total shooting region to shoot only the shooting region, and the continuous shooting speed increases as the shooting region becomes smaller. For example, a certain product can only shoot at 200 fps (frame per second) in a total shooting area of 1280x1024 resolution, but it can shoot at a speed of 1500fps or more when shooting a 320x240 shooting area. If you select the lens of the high speed image camera (220, 230) to make the 320x240 resolution physically about 14 pixels per 10mm, the shooting area is 448 x 336mm. When shooting at 1000fps at 58m / s, the top club head speed of a US PGA professional golfer, the movement of the golf club per frame is about 58mm, so you can easily shoot two or more frames with this 320 x 240 resolution shooting area. . Therefore, it is possible to determine the shooting speed of the appropriate shooting region 20 of the golf club and the high-speed video camera 220, 230 within the total shooting region 10 of the camera, and determine the shooting speed of the golf club before the golf club hit the golf ball The technology of shooting can be fully implemented with currently available products.

The size of the storage space of the internal memory of the control unit 210, the processing unit 300 or the integrated processing units 310 and 320 can be set to a size capable of storing as many image frames as desired, The size of the frame can be determined so that a sufficient number of frames can be stored.

According to an embodiment of the present invention, there are various ways to store photographed images of a golf club. One of them is that when shooting a golf club, a high-speed video camera photographs a golf club shooting area before a golf ball is hit. In this case, , The golf club shooting area is continuously photographed. In this case, many images are stored. In order to obtain the motion data of the golf club, it is not necessary to store many images since only a few golf club images are required before the golf ball is hit. Accordingly, the photographed images are stored in a circular buffer-type storage device. In the circular buffer, the most recent images are sequentially stored. When a specified storage capacity is reached, The previously stored images are sequentially discarded and stored in their place. For example, five frames are sequentially stored in a circular buffer in which five frames are stored, the sixth image is discarded and the first image is stored, and the seventh image is discarded It is stored in place. By doing so, it is possible to secure pre-strike images of the required golf clubs while minimizing storage space.
