Plate number, body color and mark identification-based equipment and plate number, body color and mark identification-based method for identifying fake plate vehicles

Abstract

The invention discloses a plate number, body color and mark identification-based equipment and a plate number, body color and mark identification-based method for identifying fake plate vehicles. The equipment comprises a video detector, a plate number positioner, a plate number identifier, a body color identifier, a mark positioner, a mark identifier, a database query and alarm device and the like. According to the characteristic that the local edge information of the plate number image is rich, the equipment can accurately position a plate number in a captured image, extract a body region and a rough mark position by using the position of the plate number, and accurately extract a body color and a mark according to the extracted rough position; and then the equipment identifies the characters of the plate number, the body color and the mark, compares the results of the three identifications with data stored in a database to determine if a vehicle is a fake plate vehicle, and gives an automatic alarm for law enforcement officials to stop the vehicle for further check if the vehicle is a fake plate vehicle. The equipment is good in structure, simple in operation, high in judgment accuracy and few in manually set parameters. The equipment can also be used for catching escaped defaulting vehicles, stolen vehicles and peccancy vehicles and the like.

Description

technical field [0001] The invention relates to a system of video image acquisition, image processing, and image recognition, which belongs to the field of computer vision and pattern recognition technology and the field of intelligent transportation applications, and is specifically designed to realize intelligent vehicle management and real-time automatic processing of illegal vehicles. system. Background technique [0002] Fake license plate vehicles are the illegal use of other people's motor vehicle license plates. The license plate is the ID card of the vehicle. In recent years, the phenomenon of fake license plate vehicles has spread across the country, resulting in frequent accidents, a sharp increase in crime, bad influence, and public grievances, disrupting the normal social order. How to effectively crack down on such illegal acts has become a difficult problem for the traffic management department. [0003] At present, the "electronic police" technology based on...

Problems solved by technology

However, when the license plate is affected by factors such as partial occlusion, stains, deformation, and large changes in ambient light, the recognition accuracy is greatly reduced, and the error is large, which brings inconvenience to traffic police law enforcement and car owners. Not enough, the judgment of vehicle identity should need more features, such as: body color, car logo, model, etc., in order to accurately determine vehicle identity and effectively combat the phenomenon of plagiarism, the present invention proposes a method based on license plate recognition, body color and vehicle Vehicle identification method based on the combination of logo identification
