PROBLEM TO BE SOLVED: To provide an object measurement device that allows a single camera to perform highly accurate three-dimensional measurement.SOLUTION: An object measurement device comprises: determination means 103 that photographs a reference image including a plurality of preliminarily stored reference points on a plane surface by a single camera 10, and determines an XYZ coordinate value of the single camera and angle of rotation thereof; calculation means 104 that photographs objects before and after a relative location between the single camera and an object on the plane surface by the single camera when the relative location therebetween varies, and calculates an effective value relevant to an exterior surface of the objects before and after the relative location therebetween varies in a ground coordinate system XYZ; and measurement means 105 that measures the XYZ coordinate value of a common specific point on the plane surface of the objects before and after the relative location therebetween varies in the ground coordinate system XYZ on the basis of the determined XYZ coordinate value of the single camera and angle of rotation thereof, the photographed photographing image, the calculated effective value, and a Z-coordinate value of the object before the relative location varies being the same as a Z-coordinate value of the object after the relative location varies. |
