Abstract
A road line recognition apparatus, including: an imaging section imaging a progress path of a own vehicle including a road to output a couple of images; an image processing section calculating a distance in a real space in a set region of at least an image on one side based on the imaged couple of images; and a detection section detecting a road line; wherein the detection section includes: a road line candidate point detection and conversion processing unit detecting a pixel on a road surface as a road line candidate point based on luminance and the distance with regard to the image on one side, and performing Hough conversion of the road line candidate point; a road line straight line detection processing unit detecting one straight line proper to the road line on each of a right side and a left side of the own vehicle based on at least a position or a behavior of the own vehicle between straight lines obtained by the Hough conversion; and a road line detection processing unit detecting the road line of a shape of a straight line or a curved line by recording a road line position which is a road line candidate point indicating a road line among the road line candidate points base…
