Abstract
An arithmetic apparatus includes: a sensor acquisition unit that collects sensor information about the surroundings of a vehicle; a feature point extraction unit that extracts a feature point of an object; a target point detection unit that expresses the position of the feature point with spatial coordinates and detects it as a target point; a road edge presumption unit that presumes a segment between the target points, which are continuously aligned, as a road edge; and a blockade judgment unit that judges whether or not to cancel the road edge, on the basis of information about an area behind the presumed road edge, which is obtained from the sensor information, where the area behind the road edge is an area opposite the sensor at the other side of the presumed road edge.
