Abstract
A vehicle recognition device includes: an acquisition section acquiring image information based on an image captured by a vehicle-mounted camera; a boundary line detection section detecting, based on the image information, boundary lines on both left and right sides demarcating vehicle traveling lanes; a vehicle detection section detecting position information on an object vehicle; and a recognition section recognizing lane-to-lane movement of the object vehicle between an own lane in which the subject vehicle is traveling and an adjacent lane. The recognition section recognizes the lane-to-lane movement based on a second boundary line of the boundary lines, a lane width between a first boundary line of the boundary lines and the second boundary line, and the position information on the object vehicle, the first boundary line dividing the own lane and the adjacent lane, the second boundary line being different from the first boundary line.
