Abstract
A travel lane boundary line detection apparatus includes: a determination unit configured to distinguish and determine a composite line region and a non-composite line region from a travel road surface image of a road surface; a calculation unit configured to calculate a candidate point of a central point of the composite line in a travel lane width direction; an extraction unit configured to detect a travel lane boundary line segment of the travel lane boundary line in the non-composite line region, and to extract a travel lane boundary point from the travel lane boundary line segment; an integration unit configured to create an integrated travel lane boundary point group based on the candidate point and on the travel lane boundary point; and an estimation unit configured to estimate a travel lane boundary line parameter representing the travel lane boundary line based on the integrated travel lane boundary point group.
