To detect specific things such as bicycles in a highly accurate manner.SOLUTION: In a device for recognizing the environment outside of a vehicle, a computer acts as: a three-dimensional object area identifying unit for identifying a three-dimensional object area in which a three-dimensional object within an image is present; a wheel area identifying unit for identifying, from the three-dimensional object area, a wheel area 214 in which wheel candidates relative to the wheels of a bicycle are present; and a wheel determination unit for determining, in the wheel area 214, whether or not the area ratio of a portion in which the relative distance to an own vehicle becomes a prescribed range is less than a predetermined value. Accordingly, it can detect specific things such as bicycles in a highly accurate manner.SELECTED DRAWING: Figure 9
【課題】自転車等の特定物を高精度に検出する。【解決手段】車外環境認識装置は、コンピュータが、画面中の立体物が存在する立体物領域を特定する立体物領域特定部と、立体物領域から自転車の車輪に相当する車輪候補が存在する車輪領域214を特定する車輪領域特定部と、車輪領域214における、自車両との相対距離が所定範囲となる部位の面積比率が所定値未満であるか否か判定する車輪判定部、として機能する。こうして自転車等の特定物を高精度に検出することができる。【選択図】図9
