An image acquisition unit in a vehicle detection device acquires an image input from an imaging device capable of imaging a scene diagonally behind a vehicle. A first image recognition unit searches an area, in the image acquired, in which to detect a vehicle located diagonally behind by using a discriminator for detecting a front of a vehicle, and detects a vehicle from within the area. A second image recognition unit extracts, in the image acquired, a plurality of feature points from within an area in which the vehicle detected by the first image recognition unit is present or estimated to be present, detects an optical flow of the feature points, and tracks the vehicle in the image. A detection signal output unit outputs a detection signal indicating that the vehicle is detected diagonally behind to a user interface.
