Abstract
A three-dimensional (3D) geometry measurement apparatus includes a projection part, a capturing part that generates a captured image of an object to be measured to which a projection image is projected, an analyzing part that obtains correspondences between projection pixel positions that are pixel positions of the projection image and captured pixel positions that are pixel positions of the captured image, a line identification part that identifies a first epipolar line of the capturing part corresponding to the captured pixel positions or a second epipolar line of the projection part corresponding to the projection pixel positions, a defective pixel detection part that detects defective pixels based on a positional relationship between the projection pixel positions and the first epipolar line or a positional relationship between the projection pixel positions and the second epipolar line, and a geometry identification part.
