What are the typical application cases of license plate recognition system?
The license plate recognition system has been maturely applied in various types of intelligent traffic and security systems. It automatically detects and recognizes vehicle number plates in images and videos. The typical application system is: red light automatic monitoring system, vehicle speed monitoring system, Motor vehicle retrograde, pressure line monitoring system, mobile electronic police system, security bayonet system and other intelligent transportation systems.
The typical application of the license plate recognition system is the security bayonet system (scientific name: road vehicle intelligent monitoring and recording system). Without the license plate recognition technology, the system has no real sense of automation intelligence. A complete security management bayonet management system should have three major functions: license plate automatic identification, bayonet application system and central network management. License plate recognition is the most important part of it. Only the bayonet system that meets the rapid and practical identification technical indicators can effectively implement automatic comparison alarm and avoid a large number of false alarms. At the same time, the recognition speed is fast, the system resources that need to be occupied by the system are small, the possibility of manual intervention is small, and the operating burden of the system network is also reduced accordingly. The merits of license plate recognition directly affect the overall performance of the bayonet system.
The license plate recognition system is an application of computer video image recognition technology in vehicle license plate recognition. The license plate recognition technology requirements can extract and identify the license plates in motion from complex backgrounds, and identify vehicle license plates, colors, and other information through license plate extraction, image preprocessing, feature extraction, and license plate character recognition technologies. The license plate recognition rate is: the recognition rate of letters and numbers can reach 99.9%, and the recognition rate of Chinese characters can reach 99.8%. The type of license plate recognition is also very complete, and all kinds of reflective and defaced can be identified.
License plate recognition system is divided into: billing version, offline version
The billing version is mainly aimed at parking lots with both temporary and fixed vehicles. Temporary vehicles can be charged according to the time of entry and exit of the vehicle, while fixed vehicles are managed according to the system recording the white list.
The offline version is a parking lot for free parking, no need for payment, when the vehicle enters or exits, the license plate recognition system recognizes the license plate and automatically raises the rod.
The license plate recognition system is now widely used in community parking lots, scenic spots, government agencies, office buildings, and commercial complexes. Every place has its own set of solutions.
Community parking lot can use the license plate to identify the billing plan. Through the effective management of the monthly rented car of the owner, the internal car of the property staff, and the visiting vehicle, the automatic access of the community monthly rented vehicle and the timely billing of the visiting vehicle are realized, and the efficiency of the community vehicle management is improved! The license plate recognition and charging system manages the access and management of the vehicles, and the fixed vehicles are authorized according to the license plate number. Once the license plate number expires, entry is forbidden and authorization must be renewed; the temporary vehicle is charged according to the license plate recognition time, and there is no validity period judgment. After entering the car, the license plate is automatically entered after it is recognized. After the license plate is identified, it is charged according to the time of entry and exit. The daily traffic volume of residential communities is very large, and the amount of data is large. System security is very important! Only a more professional parking lot identification system for parking fees can give the community the safest protection, so that owners can rest assured!
Authorities can use the license plate recognition system offline program and use embedded license plate recognition technology to solve the problem of government fixed-vehicle parking. This type of embedded license plate recognition technology provides a new management model for government user parking lots. Through the parking management solution, the government fixed vehicle license plate number can be directly imported into the license plate recognition camera. When the government’s internal vehicles enter and exit the parking lot, the system will automatically identify the license plate number and compare it with the white list in the license plate recognition camera. After successful, Barrier will be automatically released, no PC will be needed during the whole parking process, and no manual intervention will be required. If a foreign vehicle enters, the parking lot management system will prompt an unauthorized vehicle. It is forbidden to enter the car, and registration of vehicle information is required before it can be entered. This greatly improves the safety of government vehicles. The offline version of the parking management system has a simple structure, stable and reliable performance, and is easy to install, maintain, and use.
