Claim Text:
1. A method of measurement of tool dimensions which uses an image capture device which moves relative to a tool so as to capture an image of said tool and which uses the obtained image data to measure the dimensions of said tool, the method of measurement of tool dimensions comprising the steps of: capturing an image of said tool which moves along a predetermined feed direction by said image capture device at a plurality of positions and reading out a plurality of image data which are generated at the positions of said movement; specifying a contour of said tool at each of the plurality of said image data and using the specified plurality of contours as a basis to specify an angle α between a movement path of said tool and a center axial line of said tool; and specifying, based on the movement path, an angle β between a planar coordinate system of two perpendicular axes which is set in a machine tool and a planar coordinate system of two perpendicular axes which is set in a field of view of said image capture device and is linked with the planar coordinate system of the machine tool.
