PROBLEM TO BE SOLVED: To provide a marking line detector and a marking line detection method capable of improving detection accuracy for a marking line marked on a road surface.SOLUTION: A marking line detector detects positions of edges on an image of a stop line marked on a road surface around an own vehicle from an included-angle camera image and a wide-angle camera image, and detects a position of the stop line relative to the own vehicle from the detected positions of the edges. Furthermore, the marking line detector estimates the position of the stop line from the detected position of the stop line and a distance as a moving amount of the own vehicle. When detecting the positions of the edges of the stop line in an overlap common region out of the included-angle camera image and the wide-angle camera image, the marking line detector detects the stop line relative to the own vehicle in response to the position of each edge detected from the included-angle camera image and the wide-angle camera image with the estimated position of the stop line as a reference position.

    【課題】路面に標示された標示線の検出精度を向上させる標示線検出装置、標示線検出方法を提供する。【解決手段】挟角カメラ画像及び広角カメラ画像から、自車両の周囲の路面に標示された停止線の画像上のエッジの位置を検出し、検出したエッジの位置から自車両に対する停止線の位置を検出する。また、停止線の位置と自車両の移動量としての距離とから、停止線の位置を推定する。そして、挟角カメラ画像及び広角カメラ画像のうち、重なり合う共通領域で停止線のエッジの位置を検出しているときには、停止線の推定位置を基準としたときの、挟角カメラ画像及び広角カメラ画像で検出した各エッジの位置に応じて、自車両に対する停止線を検出する。【選択図】図1
