PROBLEM TO BE SOLVED: To provide a travel compartment line recognition apparatus capable of early detecting travel compartment lines defining a changed traffic lane and improving the stability of the recognition of the travel compartment lines after traffic lane change.SOLUTION: A white line recognition apparatus 20 for recognizing white lines defining a right and a left of a traffic lane in a processing region which is a predetermined region in a front image picked up by an in-vehicle camera 10 of a vehicle 40, comprises: change determination means determining whether the vehicle 40 changes traffic lanes; and change means changing the processing region in the front image from the predetermined region so as to correspond to traffic lane change while the change determination means determines that the vehicle changes traffic lanes. The change means enlarges the processing region in the direction of the traffic lane change so that a white line farther from a traffic lane before the traffic lane change out of white lines on both sides of a traffic lane after the traffic lane change is contained in the processing region.SELECTED DRAWING: Figure 2
【課題】車線変更時に、変更後の車線を区画する走行区画線を早期に検知し、走行区画線の認識の安定性を向上させることが可能な走行区画線認識装置を提供する。【解決手段】車両40の車載カメラ10により撮影された前方画像の所定領域である処理領域において、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、車両40による車線変更の有無を判定する変更判定手段と、変更判定手段により車線変更があると判定されている間、車線変更に対応するように前方画像の処理領域を所定領域から変更する変更手段と、を備える。変更手段は、車線変更の後における車線の両側の白線のうち、車線変更の前の車線から遠い側の白線が処理領域に含まれるように、処理領域を車線変更の方向へ拡大する。【選択図】 図2
