ABSTRACT:
Provided is an object measuring device capable of avoiding unnecessary scanning of an object that is unlikely to be an obstacle. By detecting a reflected light of a laser light emitted to an entire emission region, objects, other than a road surface, existing within the emission region are identified. When the objects other than the road surface are identified, a spread angle of the laser light, which is required for measuring the identified objects with a necessary accuracy, is determined. When the spread angle is determined, the laser light is emitted, at the determined spread angle, to the objects other than the road surface, and thereby the respective objects are measured.
