PROBLEM TO BE SOLVED: To provide technology capable of accurately recognizing a pair of right and left mark lines for regulating boundaries of a driving lane in a provisional section in service.SOLUTION: A mark line recognition device which is loaded on a vehicle is provided with: a line extraction part; a boundary candidate line selection part; a provisional service determination part; a learning part; and a correction processing part. The line extraction part extracts lines on a road surface from an image photographed by a photographing part. The boundary candidate line selection part selects a pair of right and left boundary candidate lines which become candidates of a pair of right and left boundary mark lines from among the extracted lines. The provisional service determination part determines whether or not the vehicle is traveling on the provisional section in service. The learning part learns lane width when the vehicle enters the provisional section in service. The correction processing part corrects a position of a right side boundary candidate line based on the lane width learned by the learning part while the vehicle travels on the provisional section in service.SELECTED DRAWING: Figure 2

    【課題】暫定供用区間において、走行車線の境界を規定する左右一対の区画線を精度良く認識することが可能な技術を提供する。【解決手段】車両に搭載される区画線認識装置は、線抽出部と、境界候補線選択部と、暫定供用判定部と、学習部と、補正処理部とを備える。線抽出部は、撮影部により撮影された画像から路面上の線を抽出する。境界候補線選択部は、抽出された線の中から、左右一対の境界区画線の候補となる、左右一対の境界候補線を選択する。暫定供用判定部は、車両が暫定供用区間を走行中か否か判定する。学習部は、車両が暫定供用区間に入ると、車線幅を学習する。補正処理部は、車両が暫定供用区間を走行中、右側の境界候補線の位置を、学習部により学習された車線幅に基づいて補正する。【選択図】図2
