PROBLEM TO BE SOLVED: To provide a three-dimensional measuring device that has improved the accuracy of three-dimensional measurement by reducing the deviation between a measurement point input into one of viewpoint images and a corresponding point set at the other of the viewpoint images.SOLUTION: A measurement point 7, which is a three-dimensional measurement reference, is input into a left viewpoint image 6L. A corresponding point 8a is set on an extension line extended horizontally from the measurement point 7 toward a right viewpoint image 6R. If a vertical deviation D occurs between the left and right viewpoint images 6L, 6R, and straight lines 24, 27 passing through the measurement point 7 and corresponding point 8a of the respective viewpoint images 6L, 6R intersect with a horizontal line with a small angle &thetas;, the corresponding point 8a is erroneously set at a position far from a true corresponding point 8. As a countermeasure to this, a corresponding point detection direction search unit is provided that, at each viewpoint image 6L, 6R, searches for a new corresponding point from the erroneously set corresponding point 8a along the straight line 27, and replaces the corresponding point 8a with the new corresponding point 8. |
