Abstract
A distance measuring apparatus includes: plural light emitters that irradiate a target whose distance is to be measured with light and are arranged along a predetermined first direction; an optical unit that directs light so that in a case where one light emitter emits light, a light amount corresponding to a central part of the light emitter and a light amount of a boundary part with an adjacent light emitter are different and in a case where plural light emitters emit light, the light amount corresponding to the central part of the light emitter and the light amount corresponding to the boundary part are equal; a light emission control unit that controls ON and OFF of the light emitters, the light emission control unit controlling the light emitters in modes including a first lighting mode in which a combination of two or more light emitters along the first direction that is ON and a combination of two or more light emitters along the first direction that is OFF alternate, a first inversion mode in which ON and OFF are reverse to those in the first lighting mode, a second lighting mode in which a combination of two or more light emitters that is ON and a combination of two or more light emitters that is OFF alternate, the combination in the second lighting mode being shifted by at least one light emitter from the combination in the first lighting mode in the first direction, and a second inversion mode in which ON and OFF are reverse to those in the second lighting mode; and a distance measurement unit that, in a case where plural light receiving regions are provided corresponding to each of the light emitters along the first direction in a region where a light receiving unit receives light from the target, performs distance measurement on a basis of a light reception result in the first lighting mode and a light reception result in the first inversion mode in a light receiving region excluding a light receiving region corresponding to a first boundary part located at a boundary between ON and OFF in the first lighting mode, and performs distance measurement on a basis of a light reception result in the second lighting mode and a light reception result in the second inversion mode in a light receiving region excluding a light receiving region corresponding to a second boundary part located at a boundary between ON and OFF in the second lighting mode.
