PROBLEM TO BE SOLVED: To enable a white line to be detected using images captured by a plurality of cameras in an area where fields of view of the cameras overlap.SOLUTION: A section line recognition device comprises a plurality of cameras installed so as to overlap fields of view partially, a feature point extraction unit for extracting feature points from the images respectively obtained from output signals of the plurality of cameras, a coordinate conversion unit for converting coordinates of the feature points extracted by the feature point extraction unit into coordinates of a world coordinate system common to the plurality of cameras, and a white line detection unit for detecting a white line on the basis of a positional relation between a plurality of feature points indicated by the world coordinate system.SELECTED DRAWING: Figure 8

    【課題】複数のカメラの視野が重複する領域において、複数のカメラの画像を用いて白線検出をすることができる。【解決手段】区画線認識装置は、一部の視野が重複するように設置された複数のカメラと、複数のカメラの出力信号から得られたそれぞれの画像から特徴点を抽出する特徴点抽出部と、特徴点抽出部が抽出した特徴点の座標を、複数のカメラに共通する世界座標系の座標に変換する座標変換部と、世界座標系で示される複数の特徴点の位置関係に基づき白線を検出する白線検知部と、を備える。【選択図】図8
