Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To simplify image processing for detecting a vehicle in an image of a camera by detecting infrared rays from the sky which are reflected by a passing windshield and detecting the vehicle according to the detection result. SOLUTION: The windshield of a vehicle which hardly transmits the temperature Tc of the vehicle and nearly reflects sky temperature Ts. The circumference radiates vehicle temperature Tc or road surface temperature Tr and Ts is normally much less than Tc or Tr, so an image obtained by an infrared camera 9 has a lower luminance level and a lower signal level in an area 13 of the windshield than at the periphery as shown in a figure (b). An infrared-ray image signal obtained at this time is as shown in a figure (c) and a low-level signal detecting circuit when detecting an image signal having an infrared-ray image signal waveform 14 below a decision level 15 outputs a detection signal 8 to output the presence of the vehicle in a picture. Vehicle detection like this is performed to easily detect the vehicle without any error without finding features of the vehicle.
