Abstract
An object of the present invention is to sufficiently consider safety of human eyes in distance measurement. The present technology relates to a distance measurement device including: an irradiation unit configured to emit light to a target space; a light receiving unit configured to receive observation light in the target space and including a plurality of light receiving elements that outputs an electric signal; a light intensity calculation unit configured to calculate light intensity in the target space, on the basis of a first electric signal corresponding to reflected light from an object irradiated with first light included in the observation light received by the light receiving unit, the first light being emitted from the irradiation unit; and a distance measurement processing unit configured to perform a distance measurement process for calculating a distance to the object, on the basis of a second electric signal corresponding to reflected light from the object irradiated with second light included in the observation light received by the light receiving unit, the second light being emitted from the irradiation unit on the basis of the light intensity calculated by the light intensity calculation unit.
