To stably identify an oncoming vehicle.SOLUTION: A vehicle exterior environment recognition device includes a first brightness image acquisition unit for acquiring a plurality of first brightness images captured at a predetermined first exposure time with a plurality of imaging devices located at different positions, a second brightness image acquisition unit for acquiring a plurality of second brightness images captured at a second exposure time that is shorter than the first exposure time with the plurality of imaging devices, a first distance image generation unit for generating a first distance image 214 that is pattern-matched with the plurality of first brightness images, a second distance image generation unit for generating a second distance image 224 that is pattern-matched with the plurality of second brightness images, a region specification unit for specifying a light source region 232 in which a light source is present, and a synthesis image generation unit for combining an image corresponding to the light source region 232 in the second distance image 224 with an image corresponding to a region 234 other than the light source region 232 in the first distance image 214 to generate a synthesis image 236.SELECTED DRAWING: Figure 9

    【課題】対向車両を安定して特定する。【解決手段】車外環境認識装置は、位置を異にする複数の撮像装置において所定の第1露光時間で撮像した複数の第1輝度画像を取得する第1輝度画像取得部と、複数の撮像装置において第1露光時間より短い第2露光時間で撮像した複数の第2輝度画像を取得する第2輝度画像取得部と、複数の第1輝度画像をパターンマッチングして第1距離画像を生成する第1距離画像生成部と、複数の第2輝度画像をパターンマッチングして第2距離画像を生成する第2距離画像生成部と、光源が存在する光源領域を特定する領域特定部と、第2距離画像224における光源領域232に対応する画像と、第1距離画像214における光源領域以外の領域234に対応する画像を合成して合成画像236を生成する合成画像生成部と、を備える。【選択図】図9
