PROBLEM TO BE SOLVED: To provide a highly-accurate three dimensional measuring device capable of searching for a corresponding point with higher accuracy.SOLUTION: A three dimensional measuring device includes a pattern projection part 4 that projects a random dot pattern onto a measuring object, the random dot pattern having a coarse area where light and dark coarsely switch each other and a dense area where light and dark more densely switch each other than the coarse area. The pattern projection part 4 has a projection pattern exchanging part 42 that exchanges the coarse area where light and dark coarsely switch each other and the dense area where light and dark more densely switch each other than the coarse area. |
