Three-dimensional measurement method and three-dimensional measurement device

Abstract

The purpose of the three-dimensional measurement method and device is to reduce occlusion while ensuring a predetermined resolution, and increase resolution without increasing occlusion. In a three-dimensional input device provided with a projection device for projecting a reference light U from an starting point A toward an object Q, and an image sensing device for receiving the reference light reflected by the object Q at a position B separated from the starting point A in the baseline direction, and the object Q illuminated by the reference light U is sensed and data specifying the position of the object are output, an anamorphic lens 51 is provided for forming an image having a magnification in the baseline direction larger than the magnification in a direction perpendicular to the baseline direction on the photoreceptive surface S2 of an opto-electric conversion device.
