PROBLEM TO BE SOLVED: To provide a travel section line recognition device capable of improving stability of recognition of a travel section line while suppressing erroneous recognition of the travel section line.SOLUTION: A travel section line recognition device comprises: detection means that detects a white line candidate as a candidate of a white line for partitioning a lane of a road on the basis of a road image captured by an on-vehicle camera 11 mounted on a vehicle 10; clearance detection means that detects a clearance included in the white line candidate detected by the detection means; and recognition decrease means that, when the clearance is detected by the clearance detection means, decreases a probability of recognizing the white line candidate as the white line up to a first probability lower than the probability in a case where no clearance is detected by the detection means, in an area from a vehicle-side edge of the clearance nearest to the vehicle 10 to a farther-side edge thereof.SELECTED DRAWING: Figure 5
【課題】走行区画線の誤認識を抑制しつつ、走行区画線の認識の安定性を向上できる走行区画線認識装置を提供する。【解決手段】車両10に搭載された車載カメラ11により撮影された道路の画像に基づいて、道路の車線を区画する白線の候補である白線候補を検出する検出手段と、検出手段により検出された白線候補に含まれる間隙を検出する間隙検出手段と、間隙検出手段により間隙が検出された場合に、車両10に最も近い間隙から遠方側において、白線候補を白線であると認識する確率を、検出手段により間隙が検出されていない場合における上記確率よりも低い第1確率まで低下させる認識低下手段と、を備える。【選択図】 図5
