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.

Whether a license plate recognition system is practical or not, the most important index is the recognition rate. International transportation technology has made a special discussion on the recognition rate index, which requires that the correct recognition rate of all signs is 85% 95% 24 hours a day. In order to test the recognition rate of a license plate recognition system, it is necessary to install the system in a practical application environment, operate for more than 24 hours all day, collect the license plate recognition of at least 1000 natural traffic flow, and store the vehicle license plate image and recognition results for retrieval and viewing. Then, we also need to get the actual passing vehicle image and the correct manual recognition results. After that, the following recognition rates can be counted: 1. Recognition rate of natural traffic flow = total number of correctly recognized full license plates / total number of actually passing vehicles 2. Percentage of recognizable license plates = total number of correctly read license plates manually / total number of actually passing vehicles 3 The correct recognition rate of the whole license plate that can be recognized = the total number of correctly recognized license plates of the whole license plate / the total number of manually read license plates. These three indicators determine the recognition rate of the license plate recognition system, such as reliability and false recognition rate, which are the intermediate results in the process of license plate recognition. The recognition speed determines whether a license plate recognition system can meet the requirements of real-time practical application. If a system with high recognition rate needs a few seconds or even minutes to recognize the results, the system will be of no practical significance because it can not meet the real-time requirements in practical applications. For example, in highway toll collection, one of the functions of license plate recognition application is to reduce traffic time, and speed is a powerful guarantee to reduce traffic time and avoid lane traffic jam in this kind of application. The recognition speed proposed by international transportation technology is less than 1 second, the faster the better.

Shenzhen Nanshan medical device industrial park started construction in 2005 and was completed and put into use in 2006. At present, it has a construction area of about 60000 m2 and covers an area of 20000 m2. There are two office buildings in phase I of the industrial park. The two to five floors are office buildings, mainly providing 800-5000 m2 of office space, and the first floor is commercial and exhibition space for supporting services. The park has sufficient supporting foundation and energy supply, with parking lot, business center, multi-functional conference hall and supporting services. The park management also adopts modern intelligent control system, mainly including: CCTV central monitoring system, which can carry out all-round real-time monitoring inside and outside the building; Electronic patrol system to strengthen the patrol management of all corners and entrances and exits inside and outside the building; Car parking management system, which can carry out parking management such as dynamic control of parking space, automatic billing and loss prevention. Due to the large number of vehicles in and out of Nanshan medical device industrial park at ordinary times, the traditional manual management is difficult to monitor in an all-round way. In order to improve the convenience and management of customers' parking, after negotiation and scheme proposal, the two sides decided to introduce tigerwong license plate recognition parking management system (Gateway version) to upgrade the parking management, Alleviate the problems of busy work and difficult parking of staff. The advent of license plate recognition parking management system (Gateway version) is an opportunity to improve parking lot management.
