PROBLEM TO BE SOLVED: To prevent a positional shift between a measured data in three- dimensional measurement and a two-dimensional image data, and to provide a data reduced in a noise caused by an unnecessary wavelength component. SOLUTION: In this measuring instrument provided with an optical projection system for projecting light toward an object, and provided with a photoreceiving optical system for receiving the reflected light, of the projected light, reflected by the object using a photoreceiving element via a photoreceiving lens system, and constituted to provide the measured data for the three-dimensional measurement based on a signal output from the photoreceiving element, the photoreceiving optical system has a bandpath filter 423 for transmitting only a wavelength range of the light projected from the optical projection system, optical filters 424-426 for transmitting a wavelength range different from that of the filter 423, and a filter selector 42 for arranging selectively one out of the filter 423 and the filters 424-426 in an optical path of the photoreceiving lens system 41. |
