Three-dimensional geometry measurement apparatus and three-dimensional geometry measurement method

A three-dimensional geometry measurement apparatus that measures a three-dimensional geometry of an object to be measured by projecting, onto the object to be measured, a projection image including a light pattern in which luminance changes depending on a position, the three-dimensional geometry measurement apparatus comprising:

• a projection part that projects the projection image onto the object to be measured;
• an image capturing part that generates a captured image by capturing the object to be measured on which the projection image is projected;
• a relationship identification part that identifies a projection pixel position which is a position of a pixel of the projection image having correspondence with a captured pixel position which is a position of a pixel of the captured image;
• and
• a defective pixel determination part that determines whether or not the pixel at the captured pixel position is a defective pixel on the basis of a positional relationship between (i) a projection light beam starting from the projection part and passing through the pixel at the projection pixel position and (ii) a captured light beam starting from the image capturing part and passing through the pixel at the captured pixel position having correspondence with the projection pixel position.
