Abstract:
1. A vehicle exterior monitoring device comprising: a position information obtaining unit that obtains position information of a three-dimensional object present in a detected region, the position information including a relative distance with respect to a subject vehicle; a first representative distance deriving unit that divides the detected region with respect to an horizontal direction into a plurality of first divided regions, and derives a first representative distance corresponding to a peak in distance distribution of each of the first divided regions based on the position information; a first divided region group generating unit that groups the first divided regions based on the first representative distance to generate one or more first divided region groups; and a second divided region group generating unit that divides the first divided region group with respect to the vertical direction into a plurality of second divided regions and groups second divided region groups having relative distances close to the first representative distance to generate a second divided region group, wherein the first representative distance deriving unit limits a target range for which the first representative distance is derived within the first divided region group in which the second divided region group is generated to a vertical range corresponding to the second divided region group.
