<p>A distance measurement system includes: a projection apparatus (1) which projects measurement beams (PL1, PL2) at least at first and second projection angles (±3, ±15. ±, ²) towards a detection area; an image pick-up apparatus (2) which picks up an image of a first reflected light (LB1) and an image of a second reflected light (LB2) from the detection area. The system further includes: a distance calculation unit (32) which calculates a first distance (d1) to a first measurement point (P2, P5) and a second distance (d2) to a second measurement point (P4, P7); a judgment unit (33) which judges that specular reflection is caused; and an operation unit (34) which, when it is judged by the judgment unit (33) that the specular reflection is caused, calculates a distance (d4) to a detection object (MB1, MB2) causing the specular reflection.</p> |
