To provide a section line detection technology capable of reducing such a situation that a detected section line becomes unfollowable.SOLUTION: A section line detection device comprises: a detection part for detecting first and second section lines from a camera photographic image; an endpoint coordinate calculation part for calculating first and second endpoint coordinates corresponding to vehicle side ends of the first and second section lines; a storage part for storing the first and second endpoint coordinates calculated by the endpoint coordinate calculation part; and a correction part for correcting the first and second endpoint coordinates stored by the storage part on the basis of an estimated moving amount of the vehicle from the previous detection time. The detection part sets a first endpoint coordinate region including the first endpoint coordinates and a second endpoint region including the second endpoint coordinates on the basis of the first and second endpoint coordinates corrected by the correction part.SELECTED DRAWING: Figure 1

    【課題】検出した区画線を追従できなくなることを低減できる区画線検出技術を提供する。【解決手段】区画線検出装置は、カメラ撮影画像から第1,2の区画線を検出する検出部と、第1,2の区画線の車両側の端部に対応する第1,2の端点座標を算出する端点座標算出部と、端点座標算出部によって算出された第1,2の端点座標を記憶する記憶部と、記憶部によって記憶されている第1,2の端点座標を前回の検出時からの車両の推定移動量に基づいて補正する補正部と、を備える。検出部は、補正部によって補正された第1,2の端点座標に基づいて、前記第1の端点座標を含む第1の端点座標領域と前記第2の端点座標を含む第2の端点座標領域とを設定する。【選択図】図1
