Abstract
There is provided a detection device that includes: a position estimator that estimates a candidate position of a crosswalk in a movement direction of a vehicle and estimates a length of the crosswalk and an intersecting angle between the crosswalk and a roadway using the candidate position; a corrector that corrects the numbers of periods and widths of two basis functions based on the estimated length of the crosswalk and the estimated intersecting angle, the two basis functions corresponding to intervals of white lines of the crosswalk and are orthogonal to each other; and a crosswalk detector that detects whether or not the crosswalk is present using both image data which include the candidate position and the two corrected basis functions.
