Abstract
A distance measurement system includes: an projection apparatus () which projects measurement beams (PL, PL) at least at first and second projection angles (α, α, β) towards a detection area; an image pick-up apparatus () which picks up an image of a first reflected light (LB) and an image of a second reflected light (LB) from the detection area. The system further includes: a distance calculation unit () which calculates a first distance (d) to a first measurement point (P, P) and a second distance (d) to a second measurement point (P, P); a judgment unit () which judges that specular reflection is caused; and an operation unit () which, when it is judged by the judgment unit () that the specular reflection is caused, calculates a distance (d) to a detection object (MB, MB) causing the specular reflection.
