License Plate Recognition Technology Opens the Sky Eye of Intelligent Transportation_ Taigewang Tech

License plate recognition technology, as a tianyantong to open intelligent transportation, is highly valued by intelligent transportation and the government. It plays a very important role in alleviating the pressure of traffic management, especially static traffic. At the same time, it is also the core subject of urban traffic information expressway construction in the 21st century, which promotes the rapid development of intelligent transportation to a great extent. So, what role does license plate recognition play in intelligent transportation? In intelligent transportation applications, in addition to extracting vehicle flow and other information, how to easily confirm vehicle identity is also very important. Among many vehicle identification methods, license plate recognition has been widely recognized by the industry for its excellent performance in application. Let's look at the working principle of license plate recognition: license plate recognition is an automatic pattern recognition technology for license plate number and license plate color by collecting dynamic video or static images of vehicles. The core of the technology includes license plate location algorithm, license plate character segmentation algorithm and optical character recognition algorithm. A complete license plate recognition system should include vehicle detection, image acquisition, license plate recognition and so on. When the vehicle detection section detects the arrival of the vehicle, it triggers the image acquisition unit to acquire the current video image. The license plate recognition unit processes the image, locates the license plate position, segments the characters in the license plate for recognition, and finally forms the license plate number output. As the identification of vehicle identity, the license plate is usually unique. No two vehicles in the world use the same legal license plate. Although two vehicles use the same license plate number abroad, they must have different license plate colors. As a vehicle identification mark, the license plate has a very standardized coding method, which provides convenient conditions for identification. For each type of license plate, the license plate format type is unique. For example, in China's ordinary civil vehicles, the first character of the license plate is Chinese characters and is the abbreviation of the province to which the vehicle belongs; The second character is a letter, and different letters represent different cities. There are also strict regulations on the color of license plates used by different types of vehicles, such as white license plates for military and police special vehicles, blue license plates for civil cars and so on. The installation position of the license plate is relatively fixed, which is installed at the fixed position at the front and rear of the vehicle, which is very conspicuous and convenient for photographing and collection. According to the uniqueness of the license plate, the license plate recognition technology will be widely used in the electronic parking toll collection system, highway toll stations and parking toll communities. The license plate recognition technology applied at the entrance and exit of the parking lot and community is mainly used to record the license plate number, license plate color and access time of the vehicle, so as to realize the automatic management of the vehicle, so as to save manpower and improve efficiency. As one of the important core technologies in the intelligent traffic management system, license plate recognition will serve the parking lot and major parking toll stations as a tianyantong to open intelligent traffic. Make people's parking life more convenient and orderly.
