In order to grasp the swing position of the user, first the swing start point should be detected using the photosensor 212 installed in the position detecting board 400. Before the start of the initial swing, that is, the golf club is prepared when the swing is prepared (a) ) Or (b).

Afterwards, when the user grabs the golf club and takes the backswing position, the golf sensor is sequentially detected by the photosensors (C) and (D).

In the control device 162, when the detection of the sensor occurs in the photosensor (C)-> (D) order, the control device 162 processes that the backswing, which is the initial stage for the swing, has occurred.

When it is determined that the control device 162 is a back swing according to the detection of the photosensor (C)-> (D), the control device 162 controls the activated analog camera 112 to take a picture. To start.

Thereafter, the signal is detected in the order of sensor (C)-> (B)-> (A), starting with the signal detection by the photo sensor (D) of the position detection board 400 by the swing operation of the user. Each signal detected by the controller is checked by the controller 160.

The golf club is all detected sequentially from the sensor (D) to (A) or sequentially from the sensor (D) to (B) or after the backswing detection of the photosensor (C)-> (D) By setting the time constant, the analog camera 112 stops capturing the image under the control of the controller 162.

In the motion analysis apparatus according to the present invention, since the analog camera 112 has a shutter speed of 1/1000 second or more per second, it is preferable to edit and reproduce the captured image at 30 frames or more per second to obtain a relatively smooth continuous screen. desirable.

In addition, in the motion capture device according to the present invention, only one image is stored in the captured image signal as a method for obtaining a captured image having a clear resolution.

In general, a video frame input by a camera combines two images in a horizontal line direction and a vertical line direction to form one image frame. However, the image produced by the two imaging synthesis as described above has a disadvantage in that the synthesized image frame is blurred because of the shooting time difference between the vertical image and the horizontal image when photographing a moving object at high speed. In order to solve this problem, the present invention provides a clear analysis image frame by selecting and storing only one of vertical and horizontal images of an image input from the analog camera 112 by the control device 162.

Such photographic storage is a well-known technique according to hardware specifications, such as currently supported by a large number of graphics boards, and thus the detailed description thereof is omitted.

As an example of golf swing motion analysis, if the swing time of the back swing started from the sensor (B) and the photo sensor (D) to the sensor (A) was set to an average of 2.2 seconds, the swing motion capture according to the present invention. The screens edited and played back by the device are all 66 frames.

As described above, in order to capture and edit an image at 30 frames per second, the present invention uses a format using an Mjpeg compression codec, which is easy to edit an image.

The user may be provided with the swing motion capture screen shot and edited as described above as a frame or a whole image through the monitor 132, and selects a desired image frame through the keypad 122 to the printer 134. You can also output via

In addition, it will be natural that the captured screen shot and edited for each frame can be transmitted to an external server through the communication unit 150 so as to be transmitted to the user by email or fax.

Golf swing motion analysis apparatus according to the present invention proposed as described above has the advantage that can implement a high-performance motion capture device using a low-cost analog camera compared to the conventional motion capture device using a digital camera.

In addition, the video recorded by the analog camera is edited using the Mjpeg codec, which makes it possible to further analyze the time difference.

Of course, in addition to the above analysis, since only one image of the vertical or horizontal image of the image captured by the analog camera is stored and used, the captured and analyzed image has a clearer image quality. There is an advantage to be easy.
