<p>PURPOSE:To improve the measuring accuracy and provide ease of fast measuring by a method wherein an auxiliary measuring plate, on which a lot of parallel measuring lines are engraved, is attached on a shaft, the auxiliary measuring plate and the groove face of a head are projected by CCD cameras, and a computer performs an arithmetic process to detect the lie and loft angles. CONSTITUTION:An auxiliary measuring plate P is a flat plate on which a lot of parallel measuring lines are engraved at regular distances, and attached on a shaft of a golf club to be detected or on the neck of the shaft. The golf club is set on a measuring table 1 so that the groove face H1 of the golf club can be seen through a window 2 and the auxiliary measuring plate P through a window 3. Then, while lit up by illuminating lamps 4 and 5, the groove face H1 and the auxiliary measuring plate P are projected by a CCD cameras 6 and 7. The image signals of the CCD cameras 6 and 7 are input to a computer 8 through an input substrate 9, and then output to a printer 10 or a display 11 after processed by an arithmetic circuit. Thereby, the lie and loft angles are simultaneously measured.</p> |
