PROBLEM TO BE SOLVED: To enable rapid detection of a specific object such as a bicycle.SOLUTION: A vehicle exterior environment recognition device includes; a target region setting unit configured to set a predetermined range of a screen as a target region 254; an edge counter configured to divide the target region with radial lines 254b extending from a center 254a of the target region to set up a plurality of divided regions 256, and to count the number of predetermined slanted edges in each of the plurality of divided regions; and a wheel determination unit configured to determine likelihood that an image is a wheel based on a proportion of the number of the slant edges to the total number of blocks.SELECTED DRAWING: Figure 6
【課題】自転車等の特定物を迅速に検出する。【解決手段】車外環境認識装置は、画面上の所定の範囲を対象領域254として設定する対象領域設定部と、対象領域の中心254aから延長された放射状の線254bが境界となるように対象領域を分割して複数の分割領域256を設定し、分割領域毎に予め定められた斜めエッジを計数するエッジ計数部と、分割領域におけるブロック総数に対する斜めエッジの割合に基づいて、対象領域の画像の車輪らしさを判定する車輪判定部を備える。【選択図】図6
