PROBLEM TO BE SOLVED: To precisely detect a road compartment line in a composite line where a deceleration sign belongs to the road compartment line.SOLUTION: A period detection unit 14 detects a sign period of a deceleration sign L2 based on detection results of a candidate detection unit 12. A section detection unit 15 detects a deceleration sign attached section B that is a section to which the deceleration sign L2 belongs by using the sign period. A road compartment line detection unit 16 detects a road compartment line L1 using a candidate P1 of the road compartment line of a section other than the deceleration sign attached section B among candidates P of the road compartment line detected by the candidate detection unit 12.SELECTED DRAWING: Figure 1
【課題】道路区画線に減速標示が付属する複合線において、道路区画線を精度良く検出する。【解決手段】周期検出部14は、候補検出部12の検出結果に基づいて、減速標示L2の標示周期を検出する。区間検出部15は、標示周期を用いることで、減速標示L2が付属する区間である減速標示付属区間Bを検出する。道路区画線検出部16は、候補検出部12で検出された道路区画線の候補Pのうち、減速標示付属区間B以外の区間の道路区画線の候補P1を用いて道路区画線L1を検出する。【選択図】図1
