Abstract:
Provided is a road surface marking detection device, comprising a road surface marking detection unit (22) which: segments an edge image, which is generated on the basis of a captured image of a road, into left and right blocks at the approximate center of the edge image; extracts, from prescribed pixel rows of the edge image, the pixel rows in which the distances between the pixels which are nearest to the approximate center in both the left and right blocks of the pixel rows are less than or equal to a prescribed value; and determines whether a road surface marking is present on the basis of the percentage of the number of extracted pixel rows with respect to the number of the prescribed pixel rows. It is thus possible to detect, with a simple configuration, a crosswalk or other road surface marking in toto.
