Abstract
Abstract In a system for detecting and warning an illegally parked vehicle a television (TV) camera images a prescribed roadside zone where parking is prohibited at a prescribed time interval. A produced still TV image is stored, and a TV image of a prescribed pattern painted on the roadside without any vehicle is stored as a reference image. The still image is compared with the reference image thereby to produce an image which carries information indicative of the presence of a vehicle in the zone and the vehicle presence information image is stored. The move-off of the vehicle is detected by comparing images of the vehicle presence information storage at a prescribed time interval. The vehicle is warned of illegal parking upon detecting that the vehicle does not move off before expiration of a prescribed time.
