PROBLEM TO BE SOLVED: To provide a travel section line recognition device that, when a one-side travel section line which has not been able to be detected becomes a state of being detectable again, can improve performance of re-detecting the travel section line.SOLUTION: There is provided a white line recognition device 20 that recognizes a white line for sectioning the right and left of a lane on a road, on the basis of a front image photographed by an on-vehicle camera 10 mounted on a subject vehicle 40. The white line recognition device 20 comprises: offset detection means that detects an amount of offset representing a positional relationship between a recognized white line and the subject vehicle 40; and prediction means that, in a case where only a one-side white line is recognized, probabilistically predicts a position of a white line on a side on which nothing is recognized, on the basis of the amount of offset detected by the offset detection means.SELECTED DRAWING: Figure 2
【課題】検知できなくなった片側の走行区画線が再び検知できる状態になった際に、走行区画線の再検知性能を向上させることができる走行区画線認識装置を提供する。【解決手段】自車両40に搭載された車載カメラ10により撮影された前方画像に基づいて、道路の車線の左右を区画する白線を認識する白線認識装置20であって、認識した白線と自車両40との位置関係を表すオフセット量を検出するオフセット検出手段と、白線が片側のみ認識されている場合に、オフセット検出手段により検出されたオフセット量に基づいて、認識されていない側の白線の位置を確率的に予測する予測手段と、を備える。【選択図】 図2
