PROBLEM TO BE SOLVED: To improve the accuracy of detecting a distant lane marking.SOLUTION: A lane marking detection system includes: an imaging apparatus 10 for imaging the surroundings of a vehicle; and a lane marking detection ECU 20. The lane marking detection ECU includes: an information extraction section which extracts depth distance information from the imaging apparatus to an object, on the basis of image information in an imaging area captured by the imaging apparatus 10; a road surface area specifying section which specifies a distant road surface area which excludes a road surface area near the vehicle in the image information and is located farther than the vehicle, on the basis of the depth distance information; and a lane marking detection section for detecting a lane marking in the distant road surface area, on the basis of image information corresponding to a position of the distant road surface area.

    【課題】遠方の区画線の検出精度を向上させること。【解決手段】自車両の周辺を撮像する撮像装置10を備え、更に、撮像装置10で撮像された撮像領域内の画像情報に基づいて当該撮像装置から撮像物までの奥行距離情報を抽出する情報抽出部と、奥行距離情報に基づいて、画像情報における自車両の直近の路面領域を除く路面領域で、かつ、自車両よりも遠方の路面領域である遠方路面領域を特定する路面領域特定部と、遠方路面領域の位置に対応する画像情報に基づいて当該遠方路面領域の区画線を検出する区画線検出部と、を区画線検出ECU20に備えること。【選択図】図1
