License Plate Recognition System of Smart City Tigerwong Technology

In real life, the traditional parking lot management mainly distributes IC cards to the vehicles entering the parking lot to record the vehicle access time as the main basis for billing. Whether fixed vehicles or temporary vehicles, they must swipe their cards at the entrance and exit before entering and leaving the parking lot. During the busy period of vehicle access, This management method often causes traffic jams and delays the owner's valuable time. In order to solve the above situation, tigerwong of our company introduced a new management concept, using license plate recognition technology to replace the traditional IC card technology to solve the traffic jam at the entrance and exit of the parking lot caused by vehicles having to stop and swipe their cards. License plate recognition is an important part of modern smart city transportation, 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. License plate recognition vehicle access management install license plate recognition equipment at the entrance and exit, record the license plate number and access time of the vehicle, and combine it 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. expressway toll management install license plate recognition equipment at each entrance and exit of the expressway, recognize the vehicle license plate when the vehicle drives in, store the entrance data into the toll system, recognize the license plate again when the vehicle arrives at the exit, call the entrance data according to the license plate information, and realize 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. system structure the basic hardware configuration of a license plate recognition system is composed of camera, main control computer, acquisition card and lighting device. The software is composed of an image analysis and processing software with license plate recognition function and a background management software to meet the specific application requirements. 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.
