ABSTRACT:
A 3-D shape measurement apparatus for grasping the state of an object with ease and accuracy is provided. The 3-D shape measurement apparatus includes: a first 3-D sensor10ahaving a projecting device11for projecting a light pattern on a target area, and a (first) image capturing apparatus12aplaced at a first interval d1from the projecting device11to capture an image of the target area on which the light pattern is projected; a second 3-D sensor10bhaving a projecting device11, and a (second) image capturing apparatus12bplaced at a second interval d2longer than the first interval d1from the projecting device11to capture an image of the target area on which the light pattern is projected; 3-D information computing means22for obtaining external shape information on an object2based on the shift of the pattern on the image acquired with the first 3-D sensor10a; variation information computing means23for obtaining variation information on the object2based on the shift of the pattern on the image acquired with the second 3-D sensor10b; and information composing means24for composing the external shape information and the variation information.
