PROBLEM TO BE SOLVED: To provide a lane mark recognition device capable of appropriately cutting calculation cost in view of a road situation in a case of recognizing lane marks.SOLUTION: A specific-candidate exclusion unit (candidate-image-part extraction unit 13) excludes at least one of a first image part that is an image part for which a corresponding position on an actual space is apart from a camera 2 by a predetermined distance or more and for which a rate of regions each having a brightness equal to or higher than a predetermined brightness or having a variation of the brightness in a boundary equal to or greater than a predetermined variation is equal to or higher than a predetermined rate, and a second image part for which a corresponding position on the actual space is apart from the camera 2 by the predetermined distance or more and for which a rate of regions of a specific color is equal to or higher than a predetermined rate. A lane mark recognition unit 14 recognizes lane marks on the basis of a region of an image for which a corresponding position on the actual space is closer to the camera 2 than the corresponding position on the actual space to the image part excluded by the specific-candidate exclusion unit.

    【課題】レーンマーク認識にあたって、道路状況に鑑みて適切に計算コストを削減することができるレーンマーク認識装置を提供する。【解決手段】特定候補除外部(候補画像部分抽出部13)は、対応する実空間上の位置がカメラ2から所定の距離以上離れている画像部分であって、輝度が所定の輝度以上又は境界における輝度の変化量が所定の変化量以上である領域の割合が所定の割合以上の第1画像部分及び特定色の領域の割合が所定の割合以上である第2画像部分の少なくとも一方を除外する。レーンマーク認識部14は、特定候補除外部により除外された画像部分よりも対応する実空間上の位置がカメラ2側となる画像の領域に基づいて、レーンマークを認識する。【選択図】図1
