Abstract: PROBLEM TO BE SOLVED: To correctly specify positions of an inner hook or an outer hook from photographed images of a spiral spring.
SOLUTION: A shape measuring device includes: an image input means for inputting the photographed images photographing the spiral spring; an image conversion means for preparing a polar coordinate images converting the photographed images in polar coordinates; and a hook position specifying means for specifying an inner hook position photographing the inner hook in the photographed images and/or an outer hook position photographing the outer hook by using the polar coordinate images. The device correctly specifies the positions of the inner hook and the outer hook from the photographed images of the spiral spring and correctly measures the shape of the spiral spring.

Abstract: PROBLEM TO BE SOLVED: To correctly measure a shape of a coil spring from captured images of the coil spring. SOLUTION: An shape measurement apparatus 10 includes: a laser 14 for irradiating a surface of the coil spring 30 with a slit light 15 expanded in the axial direction of the coil spring 30; a rotating stage 12 for rotating the coil spring 30 around its axis; a CMOS camera 16 for capturing a light reflected from the surface of the coil spring 30; and a computer 22 for calculating coordinate values of a wire of the coil spring 30 from the images captured by the CMOS camera 16 at a plurality of rotation angles when the coil spring 30 is rotated around its axis. The shape measurement apparatus 10 can correctly identify a position of the coil spring 30 from the captured images of the coil spring 30, and can correctly measure the shape of the coil spring 30.
