Abstract
A vehicle detection device includes: an antenna configured to sense electromagnetic waves; an image generation unit configured to generate a radio wave image; a road surface region detection unit configured to detect a road surface region in the radio wave image; a symmetry axis setting unit configured to set a first symmetry axis at a part of the boundary of the road surface region; a road surface reflection region setting unit configured to set a horizontal central line at a center of the radio wave image and set a road surface reflection region between the central line and the first symmetry axis; and a vehicle detection unit configured to compare the waveform of pixel outputs in the road surface reflection region with the waveform of pixel outputs in the road surface region and to detect the road surface reflection region as a vehicle.
