To appropriately perform light distribution control of a head lamp by avoiding false recognition of a visual guidance light.SOLUTION: In an outside-vehicle environment recognition device, a computer functions as: an oncoming vehicle extraction part for extracting a head lamp candidate for an oncoming vehicle from an image; a visual guidance light extraction part for determining whether a UV average value of the extracted head lamp candidate is included in a prescribed identification range in a UV plane, and excluding the head lamp candidate from the head lamp candidates by determining that the head lamp candidate is a visual guidance light when included in the identification range; and an oncoming vehicle recognition part for recognizing an oncoming vehicle on the basis of the head lamp candidate.SELECTED DRAWING: Figure 8
【課題】視線誘導灯の誤認識を回避し、ヘッドランプを適切に配光制御する。【解決手段】車外環境認識装置では、コンピュータが、画像から対向車両のヘッドランプ候補を抽出する対向車両抽出部と、抽出されたヘッドランプ候補のUV平均値がUV平面における所定の識別範囲に含まれるか否か判定し、識別範囲に含まれていれば、ヘッドランプ候補を視線誘導灯であると判定してヘッドランプ候補から除外する視線誘導灯抽出部と、ヘッドランプ候補に基づいて対向車両を認識する対向車両認識部、として機能する。【選択図】図8
