PROBLEM TO BE SOLVED: To quickly measure three-dimensional shapes at measurement parts including glossy surfaces with a simple mechanism. SOLUTION: A light source 12 is lit at a plurality of three-dimensional positions each around the measurement part P; light is successively applied to the measurement part P from different directions; an image of regular reflection light from the measurement part P is captured by a camera 20; a correspondence between the image of regular reflection light in the captured image and an irradiation direction of light each time when light is applied is calculated by a computer 30; an inclination of a circumscription plane at each measurement point on the measurement part P corresponding to the position is calculated; and a three-dimensional shape value of the measurement part P is calculated, based on the inclination of a circumscription plane at respective adjacent points on the measurement part.
