Abstract
A distance measurement apparatus that measures distance to a target by irradiating the target with laser beams and detecting light reflected by the target includes a light projection unit. The distance measurement apparatus also includes a plurality of light emission units to emit a plurality of laser beams onto the target while setting optical paths of the plurality of laser beams radially along a given virtual plane; and a light receiving unit including a plurality of light receivers to receive the plurality of laser beams projected from the light projection unit and reflected by the target.
