ABSTRACT:
A three-dimensional shape detecting device comprising projection means which projects pattern light, image capturing means which captures a pattern light projection image of a subject on which the pattern light is projected, and a three-dimensional shape calculation means which calculates a three-dimensional shape of the subject based on a locus of the pattern light extracted from the pattern light projection image. The device further comprises a first area setting means which sets a first area, including a first portion of the locus of the pattern light extending in an X-axis direction of the pattern light projection image, in the pattern light projection image; a first detecting means which detects a plurality of pixels forming the first portion of the locus of the pattern light in the first area; an approximated curve calculation means which calculates an approximated curve regarding the locus of the pattern light based on the plurality of pixels; and second area setting means which sets a second area for detecting pixels forming a second portion of the locus of the pattern light in the pattern light projection image, based on the approximated curve. The extracted locus of the pattern light is based on the plurality of pixels detected by the first detecting unit and the pixels detected in the second area.
