ABSTRACT:
A range finder for measuring a three-dimensional geometry of an object includes a projector unit for projecting the pattern light onto the object, a first image capturing unit for capturing an image reflected from the object, a second image capturing unit for capturing an image reflected from the object, an identical principal point arrangement unit, and an imaging optical system. Preferably, the second image capturing unit is arranged so as to assume a principal point optically differing from that of the first image capturing unit, the identical principal point arrangement unit arranges the projector unit and the first image capturing unit at the position of an optically identical principal point, and the imaging optical system is shared between the projector unit and the first image capturing unit.
