Abstract
A vehicle recognition apparatus according to an embodiment includes one or more hardware processors to: acquire a photographed image obtained by photographing vehicles forming a column of vehicles from an obliquely rearward direction with respect to the column of vehicles; generate a parallax image based on the photographed image; estimate a vanishing point in the parallax image; generate strip regions by dividing a region below the vanishing point in the parallax image in a horizontal direction; calculate a representative parallax for each strip region; extract strip regions efficient in recognizing a vehicle from among the strip regions based on the representative parallax; couple strip regions adjacent to each other among the extract strip regions to generate a coupled strip region based on a distance distribution model of a back surface and a side surface of a vehicle; and recognize a vehicle based on the coupled strip region.
