PROBLEM TO BE SOLVED: To provide an image processor for accurately determining whether a vehicle approaches a road white line.SOLUTION: An image processor 1 includes a candidate point detection part 2 for detecting a plurality of road white line candidate points based on a road white line included in a camera image picked up by a camera 10 provided in a vehicle, a candidate point determination part 3 for determining a plurality of representative candidate points based on coordinates of the plurality of road white line candidate points, and a determination part 4 for determining whether the vehicle approaches a road white line by using the coordinates of a reference point which is on a curve going through the plurality of representative candidate points and corresponds to an area that is not included in the camera image.
【課題】車両が道路白線に近づいたか否かを正確に判定する画像処理装置を提供する。【解決手段】画像処理装置1は、車両に設けられるカメラ10が撮像するカメラ画像に含まれる道路白線に基づく複数の道路白線候補点を検出する候補点検出部2と、複数の道路白線候補点の座標に基づく複数の代表候補点を決定する候補点決定部3と、複数の代表候補点を通る曲線上の基準点であって、カメラ画像に含まれない領域に対応する基準点の座標を用いて、車両が道路白線に近づいたか否かを判定する判定部4と、を有する。【選択図】図1
