Abstract
A range-finder, capable of finding a range by image realization, having two distantly arranged imaging devices. The first pattern having a predetermined size and the first positional information is extracted by the pattern extracting section from the first image of a target which has been made by the first imaging device. In the second image of the same target, which has been made by the second imaging device, the second pattern having the second positional information, which is most correlated with the first pattern in a plurality of upward and downward horizontal or vertical lines corresponding to the first positional information, is detected by the correlation processing section. Parallax is found from the first and the second positional information by the parallax calculating section. A distance to the target is found from this parallax by using the principle of triangulation.
