PROBLEM TO BE SOLVED: To provide a section line recognition apparatus capable of discriminating road surface reflection.SOLUTION: A section line recognition apparatus comprises: a feature point detection unit for detecting feature points, which show portions brighter than a road surface, from a photographic image; a correction unit, with frames of a photographic image at the point of time separate for a pre-set period as a first frame and a second frame, for correcting a position of a first feature point which is a feature point detected in the first frame to a position in the second frame using an acquired behavior of a vehicle and calculating the corrected position; a reflection determination unit for, in the case where a second feature point which is a feature point detected in the second frame is not present at the calculated corrected position, determining a portion shown by the first feature point corresponding to the corrected position where the second feature point is not present as a road surface reflection portion, in the first frame.SELECTED DRAWING: Figure 1

    【課題】路面反射を判別することが可能な区画線認識装置を提供する。【解決手段】撮影画像から路面よりも明るい部分を表す特徴点を検出する特徴点検出部と、車両の挙動を取得する挙動取得部と、予め設定された期間離れた時点における撮影画像のフレームを第1フレーム及び第2フレームとし、第1フレームにおいて検出された特徴点である第1特徴点の位置を、取得された車両の挙動を用いて第2フレームにおける位置に補正し、補正位置を算出する補正部と、算出された補正位置に、第2フレームにおいて検出された特徴点である第2特徴点が存在しない場合に、第1フレームにおいて、第2特徴点が存在しない補正位置に対応する第1特徴点が表す部分を路面反射部分と判定する反射判定部と、を備える。【選択図】図1
