Description

Technical Field

[0001] The utility model relates to the technical field of vehicle license plate recognition for traffic, in particular to a built-in camera of a vehicle license plate recognition all-in-one machine. Background Art

[0002] The license plate recognition integrated machine mainly uses computer vision and image recognition technology to automatically identify and recognize the vehicle's license plate number. It is usually composed of a camera, image processing software and recognition algorithm. It can be installed in road surveillance cameras, parking lot entrances, toll booths and other locations to monitor the entry and exit of vehicles or records of illegal behavior in real time. When the truck enters the weighbridge, since the vehicle already has a gross weight (corresponding to the license plate number) in the system, the license plate recognition integrated machine automatically recognizes the truck's license plate number, and the system automatically calls out the gross weight of the vehicle, which can accurately calculate the weight of the goods, eliminating a lot of manual troubles and avoiding the loss of goods assets caused by inaccurate vehicle gross weight. Compared with traditional cameras, integrated cameras are small and beautiful, easy to install and use, with a wide monitoring range and high cost performance. The license plate recognition integrated machine adds the function of license plate recognition to the integrated camera. The license plate recognition integrated camera is aimed at the parking industry and is an embedded intelligent high-definition license plate recognition integrated machine product. It exclusively integrates license plate recognition, video, front-end storage, fill light, etc., based on the license plate automatic exposure control algorithm, and has excellent imaging.
