The License Plate Recognition System Is Good- TigerWong

License plate recognition system is one of the important components of modern intelligent transportation system. It should... Expand all. Expanding all license plate recognition system refers to the technology that can detect the vehicles on the monitored road and automatically extract the vehicle license plate information (including Chinese characters, English letters, Arabic numerals and license plate color) for processing. License plate recognition is an important part of modern intelligent transportation system, which is widely used. Based on digital image processing, pattern recognition, computer vision and other technologies, it analyzes the vehicle image or video sequence taken by the camera, and obtains the unique license plate number of each vehicle, so as to complete the recognition process. Through some follow-up processing means, the functions of parking lot charge management, traffic flow control index measurement, vehicle positioning, automobile anti-theft, expressway overspeed automatic supervision, red light running electronic police, highway toll station and so on can be realized. It has practical significance for maintaining traffic safety and urban public security, preventing traffic congestion and realizing traffic automation management. The vehicle license plate number is the only "identity" identification of the vehicle. The automatic license plate recognition technology can realize the automatic registration and verification of the vehicle "identity" without any change. This technology has been applied to various occasions, such as highway toll collection, parking management, weighing system, traffic guidance, traffic law enforcement, highway inspection, vehicle scheduling, vehicle detection and so on. Several application modes are listed below: -- monitoring and alarm for vehicles included in the "blacklist", such as wanted or reported missing vehicles, unpaid vehicles, vehicles without annual inspection, hit and run vehicles and illegal vehicles, just input their license plate number into the application system, and the license plate recognition equipment is installed at the designated intersection, checkpoint or carried by law enforcement personnel at any time as needed, The system will read the license plate numbers of all passing vehicles and compare them with the "blacklist" in the system. Once the specified vehicle is found, an alarm message will be sent immediately. The system can work continuously all day without fatigue and has a very low error rate; Can adapt to high-speed vehicles; It can complete the task during vehicle operation without affecting normal traffic; In the whole monitoring process, the driver will not be aware of it and has high confidentiality. The application of this system will greatly improve the efficiency of law enforcement—— Speeding violation punishment license plate recognition technology combined with speed measuring equipment can be used for vehicle speeding violation punishment, which is generally used in expressway. The specific application is: set up speed monitoring points on the road, capture speeding vehicles and identify the license plate number, and send the license plate number and pictures of illegal vehicles to each exit; Set penalty points at each exit, identify passing vehicles with license plate recognition equipment, and compare the number with the number of speeding vehicles received. Once the number is the same, start the warning equipment and notify the law enforcement personnel for handling. Compared with the traditional overspeed monitoring method, this application can save the police force, reduce the work intensity of law enforcement personnel, and is safe, efficient and hidden. Drivers need to remind themselves not to overspeed at all times, which greatly reduces the accidents caused by overspeed—— For vehicle access management, the license plate recognition equipment is installed at the entrance and exit, the license plate number and access time of the vehicle are recorded, and combined with the control equipment of automatic door and railing machine to realize the automatic management of the vehicle. Applied to the parking lot, it can realize automatic time charging, automatically calculate the number of available parking spaces and give tips, realize the automatic management of parking charging, save manpower and improve efficiency. Applied to the intelligent community, it can automatically judge whether the incoming vehicles belong to the community, and realize automatic timing and charging for Non internal vehicles. In some units, this application can also be combined with the vehicle dispatching system to automatically and objectively record the departure of their vehicles. The license plate recognition management system adopts the license plate recognition technology to achieve no parking and no card collection, and effectively improve the vehicle access efficiency—— Automatic release inputs the specified license plate information into the system, and the system automatically reads the license plate of passing vehicles and queries the internal database. For vehicles requiring automatic release, the system drives the electronic door or railing machine to pass through, and other vehicle systems will give warnings and be handled by the personnel on duty. It can be used in special units (such as military management zone, confidentiality unit, key protection unit, etc.), road and Bridge toll checkpoints, senior residential areas, etc—— Expressway toll management installs license plate recognition equipment at each entrance and exit of the expressway. When the vehicle enters, it recognizes the vehicle license plate, stores the entrance data in the toll collection system, recognizes the license plate again when the vehicle arrives at the exit, calls the entrance data according to the license plate information, and realizes toll management in combination with the entrance and exit data. This application can realize automatic billing, prevent cheating and avoid the loss of accounts receivable. Expressway has begun to implement networked charging. With the expansion of networking scope, the charging difference of different models is becoming higher and higher. The problem of drivers using the loopholes of the existing charging system to evade fees by changing cards halfway will become more and more prominent. The use of license plate recognition technology is the fundamental method to solve this problem.
