Abstract
A traffic line recognition device includes: a traffic line region candidate extraction section that extracts a traffic line candidate, as a traffic line candidate, from a road image obtained by a TV camera installed on a vehicle; a two dimension/three dimension transform section that transforms two dimensional image coordinates of a pixel contained in the traffic line region candidate into three dimensional coordinates; a histogram production section that accumulates and projects the three dimensional coordinates onto a coordinate system in a direction crossing a road and produces a histogram in the direction crossing the road; and a traffic line judgment unit determines a traffic line based on that histogram.
