Abstract
A vehicle detection apparatus detects vehicles traveling on a road with their lights turned on. The apparatus captures images of a road, detects a light spot from captured images, and detects a first vertical coordinate of the light spot in the images. The apparatus further calculates a distance to the light spot based on a horizontal length of the light spot in the images and detects a second vertical coordinate corresponding to the calculated distance, based on correlated data in which vertical coordinates and distances in an image are correlated in advance. The apparatus further calculates a pitching amount that indicates a difference between the first and second coordinates and determines whether or not the light spot originates from a vehicle, based on the pitching amount.
