Abstract

A distance-measurement device includes: a light emitting unit emitting distance-measurement light in distance-measurement directions (D1 m , D1 n ); a light receiving unit transmitting received-light information upon receiving the distance-measurement light reflected by a distance-measurement target (MT); a calculating unit transmitting a light emission instruction to the light emitting unit and receiving the received-light information to calculate a measurement distance (ML1 m , ML1 n ) based on a time difference between the light emission and the light reception; and a complementing unit complementing a non-measurement distance (ML2 m ) of a non-distance-measurement direction (D2 m ) among the distance-measurement directions using measurement distances (ML1 m , ML1 n ) of adjacent distance-measurement directions (D1 m , D1 n ) on either side of the non-distance-measurement direction (D2 m ) in which the complementing unit complements the non-measurement distance based on a complementing process determined according to a distance difference between the measurement distances (ML1 m , ML1 n ) of the adjacent distance-measurement directions (D1 m , D1 n ) on either side of the non-distance-measurement direction (D2 m ).
