Abstract
A three-dimensional geometry measurement apparatus includes: a relationship identification part that identifies a combination of a first imaging pixel and a second imaging pixel corresponding to the same projection coordinate; a determination part that determines, whether or not at least one of the first imaging pixel or the second imaging pixel is a defective pixel on the basis of a distance between a projection pixel of the projection image; and a geometry measurement part that measures a geometry of an object to be measured using the first imaging pixel or the second imaging pixel corresponding to the combination, for which the first imaging pixel and the second imaging pixel that are determined to be not the defective pixel.
