<p><P>PROBLEM TO BE SOLVED: To provide a method for diagnosing quality of a swing without circumstance. <P>SOLUTION: A camera 10 photographs a golf player swinging a golf club to hit a golf ball and the golf club. Image data are obtained by photographing. A calculating part 16 extracts a frame from the image data, and the calculating part 16 obtains an edge image of the frame. The calculating part 16 subjects the edge image to binarization based on a predetermined threshold to obtain a binary image, and the calculating part 16 subjects the binary image to Hough transform processing to extract a position of a shaft of the golf club, and specifies a tip coordinate of the golf club. The calculating part 16 contrasts tip coordinates of different frames with each other to determine a temporary frame in an address. The calculating part 16 calculates color information in a reference area of each frame by backward sending from a frame after the temporary frame by a predetermined number, and determines a frame in the address based on the change of the color information. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
