Abstract
A recognition sensor includes a three-dimensional sensor and a controller. The three-dimensional sensor scans a scan beam in the horizontal direction, and measures the distance up to each of multiple measurement points defined on a scan line. The controller corrects the elevation angle of the three-dimensional sensor such that the height of a correction point, which is selected from among the multiple measurement points, approaches a predetermined value.
