Application of license plate recognition system solution

General speaking, the license plate recognition system is an equipment used to identify car license plates. The early license plate recognition system was used for parking charging only. Nowadays, the license plate recognition parking system is more intelligent and has many modern functions.

Lide license plate recognition parking system has a 4 million high-definition pixel starlight imaging camera, supports dynamic and static QR code payment modes, and adopts unique cloud operation and maintenance and unattended management procedures, so that the license plate recognition parking system can not only identify and record the license plate and vehicle information clearly and efficiently (the license plate recognition rate is over 99.5%), but also supports a variety of humanized functions such as high-definition monitoring, electronic payment, nighttime fill-in light, and voice broadcast.

The license plate recognition system is also a technology that can detect vehicles within the monitoring range and automatically extract license plate information for processing. The license plate recognition system is one of the most important parts of modern intelligent transportation and smart parking. It is often used with boom barriers and has a wide range of applications.

The license plate recognition parking system integrates digital image processing, pattern recognition, computer vision and other technologies and can analyze the vehicle images or video sequences captured by the camera and finally complete the recognition process based on the unique license plate number of each vehicle.

Camera

The license plate recognition parking system uses a high-resolution camera to capture the entry and exit of vehicles and obtain license plate images.

Image acquisition and preprocessing

Convert the video images captured by the camera into digital images through image acquisition cards or image sensors, and perform preprocessing on the images, such as denoising, contrast enhancement, etc., to improve subsequent license plate recognition accuracy.

License plate detection and positioning

In the pre-processed image, the license plate detection algorithm is used to accurately locate the license plate position, that is, to determine the area of the license plate in the image.

Character segmentation and recognition

Based on the positioning results of the license plate, character segmentation is performed on the license plate area to separate each character on the license plate. Then a character recognition algorithm is applied to recognize the segmented characters as corresponding letters or numbers.

License plate information processing and storage

The recognized license plate information can be used for a variety of purposes, such as automatic access control, parking lot management, traffic violation monitoring, etc. The system can process, store, and transmit recognition results to meet specific application needs.

01. Safe and fast vehicle entry and exit

The license plate recognition system can recognize the license plate rapidly, avoiding all inconveniences caused by card and ticket collection in rainy and snowy weather and eliminating the hazards caused by the vehicle rolling away and stalling when the driver is collecting cards.

02. Rapid and diversified payment

Besides charging a fee at the exit of the parking lot, the system also provides a variety of payment methods, such as self-service payment terminals, paying by third-party APP (such as WeChat), merchant payment, and handheld payment terminals, which helps to improve payment efficiency.

03. High traffic efficiency in the parking lot

The integrated license plate recognition system and barrier gate can enable the maximum traffic efficiency at the entrance to reach 20 vehicles per minute. Combined with the self-service payment terminal, the exit can also achieve the same traffic efficiency as the entrance, avoiding congestion and queuing of vehicles inside and outside the parking lot.

04. Avoid the risk of charging loopholes

With the license plate recognition system gate all-in-one machine, the system does not use IC cards as the charging medium, which can effectively prevent common toll evasion methods in parking lots such as changing cards and using one card for multiple vehicles, etc. At the same time, the system has a strict fee settlement and fee audit management system, which can avoid charging loopholes caused by various human reasons to the greatest extent and ensure that parking fees are collected in full and truthfully.

05. Reduce operating and maintenance costs

Using the integrated license plate recognition system and barrier machine can significantly reduce operating costs and save human resource expenditures. The annual savings in card issuer fees will be considerable, and many unpredictable security risks will be avoided. At the same time, it also effectively improves service quality and reduces the management workload.

Application scope of license plate recognition system

Surveillance and monitoring

For vehicles included in the "blacklist” (such as vehicles that are wanted or reported lost, vehicles with unpaid fees, vehicles without annual inspection, hit-and-run and illegal vehicles, etc.), the license plate recognition system only needs to enter its license plate number into the application system. The license plate recognition equipment is installed at designated intersections, checkpoints or carried by law enforcement officers at any time and placed 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 listing vehicle is found, an alarm message will be issued by the system immediately. The system can work uninterrupted throughout the day without fatigue, and the error rate is extremely low. The application of this system will greatly improve the efficiency of law enforcement.

Violation monitoring

The license plate recognition system, combined with speed measuring equipment, can be used to punish vehicles for speeding violations and is generally used on highways. The specific application is: setting up speed monitoring points on the road; capturing speeding vehicles and identifying license plate numbers; sending the license plate numbers and pictures of illegal vehicles to each exit; setting up penalty points at each exit; and using license plate recognition equipment to identify passing vehicles and compare their license plate number with the number of the speeding vehicle that has been received. If the number is the same, the warning will be activated to notify law enforcement personnel to deal with it. Compared with traditional speed monitoring methods, this application can save police resources and reduce the work intensity of law enforcement personnel. It is also safe, efficient, and concealed. Drivers need to always remind themselves not to speed, which greatly reduces accidents caused by speeding.

Automatic passing

After inputting the specified license plate information into the license plate recognition system, the system will read the license plates of passing vehicles and query the internal database automatically. For vehicles that need to be automatically released, the system drives the barrier gate to let them pass. For other vehicles, the system will give a warning signal, which will be handled by the on-duty personnel. It can be used in special institutions (such as military management areas, confidential institutions, key protection institutions, etc.), road and bridge toll gates, high-end residential areas, etc.

Parking lot management

Install the license plate recognition system at the entrance and exit to record the license plate number and entry and exit times of the vehicle, and combine it with the control equipment of automatic doors and railings to realize automatic management of vehicles. When applied to parking lots, it can realize automatic timing charging, and can also automatically calculate the number of available parking spaces and give prompts, realizing automatic parking charging management, saving manpower and improving efficiency.

Highway payment management

Install a license plate recognition system at each entrance and exit of the highway. When the vehicle enters, the vehicle license plate is recognized and the entrance information is stored in the toll system. When the vehicle arrives at the exit, its license plate is recognized again and the entrance information is called according to the license plate information. Combined with entry and exit information, it realizes charge management. This kind of application can realize automatic billing and prevent cheating, avoiding the loss of receivables.

Automatic registration of license plate numbers

The traffic supervision departments must deal with many pictures of illegal vehicles every day. They usually manually identify the license plate numbers and then input them into the management system. This method is heavy in workload and prone to fatigue and misjudgment. The use of license plate recognition systems can reduce work intensity and greatly improve processing speed and efficiency. This functionality can be used in electronic police systems, road monitoring systems, etc.
