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.

Claim (Index 16):
A three-dimensional (3D) geometry measurement method wherein the 3D geometry measurement method measures a 3D geometry of an object to be measured by projecting a projection image including a stripe pattern onto the object to be measured, the method comprising:\n projecting the projection image onto the object to be measured; generating a captured image of the object to be measured onto which the projection image is projected; obtaining correspondence between projection pixel positions that are pixel positions of the projection image and a captured pixel positions that are pixel positions of the captured image; identifying a first epipolar line of a capturing part corresponding to the captured pixel positions or a second epipolar line of a projection part corresponding to the projection pixel positions, the capturing part generating the captured image of the object to be measured and the projection part projecting the projection image onto the object to be measured; detecting a defective pixel on the basis of a positional relationship between the projection pixel position and the first epipolar line or a positional relationship between the projection pixel position and the second epipolar line; and identifying the 3D geometry of the object to be measured on the basis of correspondence of pixel positions excluding the positions of defective pixels detected from among the correspondences being obtained.
