Summary: | The present invention provides a technology capable of measuring three-dimensional shapes by applying a stereo method even in the case that an object has a specular surface. A shape measuring apparatus 1 is equipped with a pattern position specification section 20 (before-movement pattern position specification section, after-movement pattern position specification section), an image capturing position calculation section 30 (before-movement image capturing position calculation section, after-movement image capturing calculation section), a pixel area specification section 40 (second pixel area specification section), an inclination angle calculation section 50 (before-movement inclination angle calculation section, after-movement inclination angle calculation section), a height-direction coordinate determination section 60, and an output section 80. |
