PROBLEM TO BE SOLVED: To provide a travel compartment line recognition apparatus capable of suppressing the delay in recognizing travel compartment lines defining a changed traffic lane and improving the stability of the recognition of the travel compartment lines after traffic lane change even when a traffic lane is changed to the traffic lane having a traffic lane width changed from a width of the former traffic lane.SOLUTION: A white line recognition apparatus 20 for recognizing white lines defining a right and a left of a traffic lane on the basis of a front image picked up by an in-vehicle camera 10 of a vehicle 40, comprises: learning means calculating a traffic lane width from the white lines detected on the basis of the front image and learning the calculated traffic lane width; restriction means restricting an allowable range in the front image for allowing the detection of the white lines on the basis of a learned value of the traffic lane width learned by the learning means; and change determination means determining whether the vehicle 40 changes traffic lanes, the restriction means enlarging the allowable range restricted on the basis of the learned value when the change determination means has determined that the vehicle changes traffic lanes.SELECTED DRAWING: Figure 2

    【課題】車線幅が変化する車線へ車線変更する場合でも、変更後の車線を区画する走行区画線の認識の遅れを抑制し、車線変更後の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に基づいて、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、前方画像に基づいて検知された白線から車線幅を算出し、算出した車線幅を学習する学習手段と、学習手段により学習された車線幅の学習値に基づいて、前方画像において白線の検知を許容する許容範囲を制限する制限手段と、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、を備え、制限手段は、変更判定手段により車線変更があると判定された場合に、学習値に基づいて制限した許容範囲を広げる。【選択図】 図2
