1. Brief Introduction


LOYALTY-SECU License Plate Recognition System (LPRS) is a technology that mainly focuses on software, which enables the computer system to automatically read the vehicle registration number (license number) from the digital picture.

 Automatically reading the registration number means converting the pixels of the digital image into the ASCII text of the license plate.

Although Automated license plate readers (ALPRs) has a special type of OCR technology, nowadays, optical character recognition (OCR) technology is strictly regarded as a technology-mainly software-that allows you to scan paper documents and convert them into electronically editable files.


From the perspective of LPR/ANPR, image quality is always the key factor. The capture of fast-moving vehicles requires special techniques to avoid motion blur, because motion blur will greatly reduce the recognition accuracy. In order to ensure the correct image quality, a combination of high-power lighting and a short shutter time is required.

The Automatic License Plate Recognition System can perform high-performance automatic license plate detection and recognition in real time or from recorded video. This AI-driven system collects high-quality images, time stamps and complete data of GPS coordinates. With its flexible and extensible design, the license plate recognition system can be customized to meet the requirements of various fixed or mobile applications in private and government departments.

The appearance of ALPR Camera is the same as that of model LY-ALR-003 basically. They are sister models except different display screen position. It is a complete basic ANPR solution to meet the basic demands of license plate recognition function.

3. Main Function of Hardware Components

ALPR Solution: it mainly captures pictures, which are sent to the software for recognition. There are two ways to trigger the camera to capture pictures. One is that the camera itself has a head-detection function, and the other is that the car is triggered by the ground sense coil and vehicle detector when vehicle pass to capture the picture.

Column: the column and the appearance of the product are formed by cold-rolled iron sheet, strong and waterproof.

Fill light: With an automatic light sense < 30Lux, the light will be automatically opened according to the surrounding environment of the project site, and will remain bright until the supplementary light detects that the surrounding environment becomes brighter, and the light sense will be automatically closed when it is greater than 30Lux.

4. Main function of ALPR Camera System

Supports recognize the license plates of more than 120 countries and output the results
ALPR software manages the whole parking lots from entrance and exit to charging, like control vehicle barriers, gates, traffic lights, and message signs etc.

Set the charging rules of the parking lot, limited free time parking, parking fee charge rule via cash or coin or credit card, then system will charge them automatically as per setting rule, such as the first three hours being free which reverts to paid parking for longer stays automatically.

Provide the real-time reports on vehicle license plate, journey times, stay times, flow rates and entry/exit balance, and the vehicle alerts can be sent by email or text message.

ALPR Camera with parking lot software supports vehicle license plate registration and inquiry, keeps a record of live and historical car park data usage, and forms a traffic report for easy parking lots management.

Networking ALPR  Camera System can across a site or multiple sites to manage different parking lots.

The best solution of a set of parking software is to manage the parking lot with one in and one out. It can also be used for two in and two out. If beyond this range, it may affect the efficiency of management or cause the situation of stagnation, which also depends on the actual use of computers and the amount of vehicles.

LOYALTY-SECU ALPR License Plate Recognition Camera support the data output to other systems, like parking system, access control, weighbridge system etc. LOYALTY-ECU can offer SDK for second development, easy to integrate to other management platform. And Our ANPR software is compatible with SQL, Oracle, Excel and CSV files.

5. The Workflow of ALPR/ANPR Solution

Process description:

Entry: the Automatic License Plate Recognition System captures an image by means of vehicle head detection or loop coil trigger or camera detector, and the image is transmitted to the software.

The software algorithm recognizes the image, writes the recognition result into the database and returns it to the camera, and the camera sends the switch signal to barrier switch.

Exit: the license plate recognition camera captures an image by means of vehicle head detection or loop coil trigger or camera detector, and the image is transmitted to the software.

The software algorithm recognizes the image, outputs the recognition result and compares it with the entrance recognition result in the database. The comparison is successful and the result is returned to the camera.

9. Different Installation Environment

There is no turn of the lane, the recognition distance shall be 4-5 meters from the camera horizontal line, and the vertical angle should not exceed 30 degree, the horizontal angle not exceed 55 degree. When there is a turn, leave enough space for the vehicle to turn to ensure that the vehicle is straight before entering the recognition area.

If there is a distance of 4-5 meters before entering the slope, it is recommended that the entrance and exit be installed before entering the slope. Please be careful to avoid backlighting.

If there is not enough distance, the equipment can be disassembled to choose a suitable installation location. Confirming the camera’s recognition distance of 4-5 meters, and adjust the camera’s elevation or depression to ensure that the license plate is displayed horizontally in the lens. Generally, the angle of a straight slope does not exceed 15%, and the angle of a curved ramp does not exceed 12%. During construction, the installation angle of the camera can be adjusted according to the angle of the slope.

The position of the ground sensing coil and the vehicle detector in the slope can be constructed according to the texture of the slope. If the site conditions permit, the ground sensing coil should be constructed on a level ground as much as possible.

If the camera‘s position is somewhere above the slope, then two reduction gear should be installed at 6 and 7 meters from the camera’s horizontal line to ensure that the vehicle’s travel speed is less than 30km / h. At the exit, the installation principles are similar, but only one reduction gear is required at 6 meters.
