Abstract
A distance measurement apparatusincludes a light emitting unitthat irradiates a subject with a light-source light from a light source, a light receiving unitthat receives a reflected light from the subject, a distance calculation unitthat calculates a distance to the subject based on a time difference from the irradiation of the light-source light to the reception of the reflected light; and an image processing unitthat generates a distance image of the subject based on the calculated distance. Further, the apparatus includes a first rotation mechanismthat adjusts an irradiation angle of the light emitting unit and a second rotation mechanismthat adjusts a light receiving angle of the light receiving unit, in which the angles of the light emitting unit and the light receiving unit may be adjusted independently of each other.
