License Plate Recognition System Routine Deep Car Main Think Twice- TigerWong Technology

We have seen a lot of reports on the Internet. In order to avoid the arrest of the electronic police, some drivers are smart enough to think of a deck of cards and block the license plate, thinking that the electronic eye can't see it. This is a cover up, which has no effect. Now the new regulations severely punish the methods of deck, shielding and so on, and seriously revoke the driver's license and impose a fine. Therefore, car owners should not set an example and think twice! The electronic police system, also known as the traffic violation detection system, is usually set at urban intersections to detect traffic violations such as running red lights, retrograde, driving not according to the guide lane at intersections, and identify the license plate of illegal vehicles. The picture records and license plate recognition results of illegal acts are used as law enforcement evidence for the punishment of traffic violations. So why can e-police monitor all this so clearly? How to recognize license plates at intersections and urban traffic? The one and only the one and only China ID number is license plate recognition system identity card. Every Chinese citizen has a unique identity card. The car actually has its own identity card, that is, the license plate number. It is also unique as our ID card number. The license plate is the only identity card. It is an important part of electronic police. License plate recognition system is a pattern recognition technology for automatic recognition of license plate number and license plate color by using dynamic video or static image of vehicle. The core of the technology includes license plate location algorithm, license plate character segmentation algorithm and optical character recognition algorithm. The license plate recognition system adopts a highly modular design, and takes each link of the license plate recognition process as an independent module: vehicle detection: various ways such as buried coil detection, infrared detection, radar detection technology and video detection can be used to perceive the passing of vehicles, And trigger image acquisition and capture image acquisition: conduct real-time and uninterrupted recording of passing vehicles through the HD camera capture host, acquisition and correction processing: noise filtering, automatic white balance, automatic exposure, gamma correction, edge enhancement, contrast adjustment and other license plate positioning: conduct row and column scanning on the gray image after image preprocessing, Determine the character segmentation of the license plate area: after locating the license plate area in the image, accurately locate the character area through graying and binarization, and then segment the character according to the character size characteristics. Character recognition: zoom and extract the segmented characters, Match with the standard character expression form in the character database template and output the discrimination results: output the license plate recognition results in text format. The future license plate recognition system technology will play a more important and positive role in maintaining traffic safety and urban public security, preventing traffic congestion and alleviating traffic tension!
