License Plate Recognition System Plays an Important Role in Realizing Vehicle Automatic Management_

In real life, the traditional parking lot management is mainly to issue cards to vehicles entering the parking lot or arrange managers to register vehicle information, so as to record the time of vehicles entering and leaving as the main basis for billing. Whether fixed vehicles or temporary vehicles, they must swipe their cards at the exit or pay manually before leaving the parking lot. This type of management often leads to traffic jams and wastes the owner's valuable time. In order to solve the above problems, using license plate recognition technology to replace the traditional manual card management plays an important role in realizing vehicle automatic management. License plate recognition is one of the important components of modern intelligent urban transportation and is widely used. Based on digital image processing, pattern recognition, computer vision and other technologies, analyze the image or video sequence of the vehicle captured by the camera, and obtain the unique license plate number of each vehicle, so as to complete the recognition process. System structure the basic hardware configuration of license plate recognition system is composed of camera, main controller, acquisition card and lighting equipment. The software level consists of image analysis and processing software with license plate recognition function and background management software to meet specific application requirements. It is applied in highway toll management. At present, license plate recognition equipment is installed at the entrances and exits of expressways. When the vehicle enters the expressway, the system recognizes the license plate and stores the data in the toll collection system. When the vehicle reaches the exit, recognize the license plate again and call the entrance data according to the license plate information.

Expressway has begun to implement network charging. With the expansion of network scope, the charging price gap of different types of vehicles is becoming larger and larger. Drivers often use loopholes in the existing charging system to evade fees. License plate recognition technology is the fundamental method to solve these problems. The license plate recognition equipment for managing vehicle access in the parking lot is installed at the entrance and exit of the parking lot, records the license plate number and vehicle access time, and combines it with the road gate to realize the automatic management of vehicles. It can be applied to the parking lot to realize automatic charging, and can also automatically calculate the number of available parking spaces and give tips.
