In order to solve the above problems, the use of license plate recognition technology to replace the traditional manual card management has an important role in achieving automatic vehicle management.

License plate recognition is one of the important components of modern smart city traffic and is widely used. Based on digital image processing, pattern recognition, computer vision and other technologies, analyze the camera images or video sequences taken by the camera to obtain the unique license plate number of each vehicle, thus completing the recognition process.

system structure

The basic hardware configuration of the license plate recognition system consists of a camera, a main controller, a capture card and lighting equipment. The software level is composed of image analysis and processing software with license plate recognition and background management software that meets specific application needs.

Application in highway toll management

Now all the highways have installed license plate recognition equipment at the entrance and exit. When the vehicle enters the highway, the system recognizes the license plate and stores the data in the toll system

When the vehicle reaches the exit, the license plate is recognized again and the entrance data is called according to the license plate information.Combining entrance and exit data to realize toll management, which can realize automatic billing and prevent vehicle owners from using loopholes to evade tolls.Expressway has started to implement toll collection.

Drivers often use the loopholes in the existing toll system to evade tolls. License plate recognition technology is the fundamental to solve these problems.

Manage parking lot access

The license plate recognition device is installed at the entrance and exit of the parking lot, records the license plate number and the time of the vehicle entry and exit, and combines it with the barrier to realize the automatic management of the vehicle

When applied to parking lots, automatic toll collection can be achieved, and the number of available parking spaces can be automatically calculated and given a reminder. Automatic parking fee management can save manpower and improve efficiency.

Applied to the cell can automatically determine whether the entering vehicle belongs to the local cell, and charge for non-internal vehicles.

In some units, this application can also be combined with the vehicle scheduling system to automatically and objectively record the vehicles outbound status.The license plate recognition technology is adopted to realize the card-free inspection without stopping, which effectively improves the efficiency of vehicle entry and exit.
