Abstract:
1. A vehicle detection device, comprising: an antenna configured to sense electromagnetic waves radiated from an object; an image generation unit configured to generate a radio wave image based on the electromagnetic waves received by the antenna; a road surface region detection unit configured to detect a road surface region in the radio wave image based on the electromagnetic waves received by the antenna; a symmetry axis setting unit configured to set a first symmetry axis at a part of a boundary of the road surface region, the part having a horizontal length not less than a predetermined value; a road surface reflection region setting unit configured to set a horizontal central line at a center of the radio wave image in a vertical direction and set a road surface reflection region between the central line and the first symmetry axis; and a vehicle detection unit configured to compare a waveform of pixel outputs in the road surface reflection region with a waveform of pixel outputs in the road surface region and to detect the road surface reflection region as a vehicle when the waveform of pixel outputs in the road surface reflection region has a similar feature to that in the road surface region.
