PROBLEM TO BE SOLVED: To provide a travel section line recognition device capable of suppressing erroneous recognition of a travel section line which is caused by a branch.SOLUTION: A travel section line recognition device (1) comprises: an image acquisition unit (3) for acquiring an image obtained by photographing an area ahead of a subject vehicle; a recognition unit (5) for recognizing a travel section line; a map information acquisition unit (7) for acquiring information on a map; a position information acquisition unit (9) for acquiring information on a position of the subject vehicle; an on-map position acquisition unit (11) for acquiring a position of the subject vehicle on the map; a section setting unit (13) for setting a section that continues over a section length B in a travelling direction of the subject vehicle from a position which exists away from a branch position by an offset distance A on a subject vehicle side; and a determination unit (15) for determining whether the on-map position of the subject vehicle is within the section. The recognition unit places restrictions on recognizing the travel section line on a branch road side when it is determined that the on-map position of the subject vehicle is within the section.SELECTED DRAWING: Figure 1

    【課題】分岐に起因する走行区画線の誤認識を抑制できる走行区画線認識装置を提供すること。【解決手段】自車両の前方を撮影した画像を取得する画像取得ユニット(3)と、走行区画線を認識する認識ユニット(5)と、地図情報を取得する地図情報取得ユニット(7)と、自車両の位置情報を取得する位置情報取得ユニット(9)と、自車両の地図上での位置を取得する地図上位置取得ユニット(11)と、分岐位置よりもオフセット距離Aだけ自車両側にある位置から、自車両の進行方向に、区間長Bにわたって継続する区間を設定する区間設定ユニット(13)と、自車両の地図上での位置が区間内にあるか否かを判断する判断ユニット(15)とを備え、認識ユニットは、自車両の地図上での位置が区間内にあると判断した場合は、分岐路の側における走行区画線の認識を制限することを特徴とする走行区画線認識装置(1)。【選択図】図1
