ABSTRACT:
A three-dimensional vision camera where there is no disagreement between the video signal and the distance signal is provided by using the taking optical system for the distance measurement. A reflecting mirror 8 for reflecting a distance measuring laser beam from a laser diode 6 is arranged behind a taking lens 4. The laser beam is irradiated to a photographic object through the taking lens 4. The laser beam reflected by the photographic object is received by a photodiode array 7 through the taking lens 4 and the reflecting mirror 8. While the taking lens 4 is moved along the optical axis to perform photographing, the laser scanning is performed by rotating the reflecting mirror 8 about two axes vertical to the optical axis of the taking lens 4 to measure the distance.
