PROBLEM TO BE SOLVED: To provide a three-dimensional shape measuring method reduced in an error by restoring a three-dimensional shape using a large color distance pattern light.;SOLUTION: In this pattern filter 1 for a pattern light for imaging a solid object projected with the pattern light passed through a filter divided into band-like areas to measure a three-dimensional shape based on a picked-up image, the projected pattern projected by the pattern filter has a plurality of slit lights. The slit lights form a slit light array patterns comprising the slit lights having equivalent color distances, and the slit light array patterns are arranged with the same distance to the pattern lights.;COPYRIGHT: (C)2005,JPO&NCIPI
