<P>PROBLEM TO BE SOLVED: To provide a measuring method of a measuring object on a printed circuit board. <P>SOLUTION: In order to measure the measuring object on the printed circuit board, three-dimensional height information of the printed circuit board is obtained by utilizing a first image photographed by irradiating the printed circuit board with grid pattern light by utilizing a first illumination unit. Then, a first domain projecting higher than a reference height is defined as the measuring object on the printed circuit board by utilizing the obtained height information. Thereafter, color information of the printed circuit board is obtained by utilizing a second image photographed by irradiating the printed circuit board with light generated from a second illumination unit. First color information in the first domain defined in the measuring object in the obtained color information of the printed circuit board is set as reference color information. Then, color information in a domain other than the first domain is compared with the reference color information, to thereby determine whether the measuring object is formed in the domain other than the first domain or not. <P>COPYRIGHT: (C)2011,JPO&INPIT |
