Vehicle license plate recognition system for traffic violation detection

Abstract

The invention provides a vehicle license plate recognition system for traffic violation detection for obtaining vehicle information in traffic violation and recognizing the license plate of an illegal vehicle at the crossroad. The vehicle license plate recognition system comprises a video monitoring unit, an angle information synchronization unit and a video collection unit; the video collection unit comprises an even number of recognition units which are arranged into a ring; each recognition unit comprises a wireless data transmission device and a video collection device; and each video collection device has a high-definition shooting mode and an ordinary-definition shooting mode. According to the vehicle license plate recognition system, the shooting definition of the video collection device can be adjusted according to the angle information synchronization unit, so that the success rate of license plate recognition is greatly increased; and unnecessary waste of a video storage space is reduced.

Description

technical field [0001] The present invention relates to the technical field of license plate recognition, and more specifically, to a license plate recognition system for illegal detection. Background technique [0002] With the rapid development of my country's national economy, there are more and more domestic motor vehicles, expressways, urban roads, parking lots, etc., and the requirements for traffic control and safety management are also increasing. The intelligent transportation system ITS (Intelligent Transportation System) has It has become the development trend of road traffic management in the 21st century and has been paid more and more attention by people. Among them, the license plate recognition system, as the core part of intelligent traffic management, provides an efficient and practical means for automated intelligent traffic management, and can be widely used in road traffic monitoring, traffic accident scene investigation, automatic recording of traffic vi...

Problems solved by technology

Currently, most of the license plate recognition products in my country rely on hardware trigger systems to capture images to identify license plates, such as magnetic induction coils, infrared, radio frequency, etc. The trigger rate is relatively high, but the installation and maintenance costs of hardware equipment are relatively high.

With the rapid development of computer technology, the speed of computer calculation has been significantly improved, and the video-based license plate recognition system has attracted more and more attention. Its advantage is that it avoids the dependence on hardware equipment and thus reduces the cost. The recognized image is a frame in the video, which is affected by the car's driving direction, speed, and other external disturbances, and the quality of the acquired image is not as good as that of a static image
