Abstract
A three-dimensional shape measurement system includes: an articulated robot having a plurality of axes; at least one three-dimensional vision sensor mounted to the articulated robot and configured to measure a three-dimensional shape of an object to be imaged; a storage unit configured to store distance images representing the three-dimensional shape measured respectively in a plurality of measurement areas including an overlap region; and an integrating unit configured to integrate the plurality of distance images stored in the storage unit in such a manner that parts of the distance images corresponding to the overlap region are superimposed on each other, to thereby generate an integrated distance image.
