What Is License Plate Recognition (LPR) Software?

The license plate recognition software enables camera devices to capture images of license plates in order to recognize the characters. It leverages computer vision through Artificial Intelligence (AI) algorithms to read and interpret the characters on a license plate.

Key Features of Our Number Plate Recognition System

The following are some significant features of our ANPR system:

Multi-Region & Multi-Alphabet Support

Our LPR software keeps you covered, no matter where you deploy it. Our system supports major geographic areas: Europe, North America, South America, the Middle East, Africa, and the Asia Pacific (APAC). Similarly, for enhanced adaptability, it supports Latin, Arabic, Cyrillic, and Thai alphabets.

Cloud & Edge Deployment Options

Do you have a cloud-based traffic monitoring system in place? Or else do you prefer processing vehicle images through a locally connected device? Our car plate recognition system is compatible with both, as we offer both versions.

Hardware & Camera Compatibility

• Our number plate recognition software is compatible with Windows 10 and 11 operating systems.
• It supports various processors, including Intel CPUs, NVIDIA GPUs, and Halio-8.
• It is compatible with the following industrial cameras: Basler, Daheng, Flir, and IDS Imaging cameras.
• It may process images via RTSP
• It has a software-protected license.
• Installing a dedicated board won’t be necessary.

Real-Time Accuracy & Performance

The license plate recognition ANPR supports multiple license plate formats. Our SDK leverages the GPU’s power, enabling hardware acceleration. We train the AI models with millions of license plates, enabling our SDK to achieve optimal image processing with millisecond accuracy.

How Our License Plate Recognition SDK Works

Let’s understand the working of our car plate recognition system in some simple steps:

• The system feeds the vehicle’s images or clips, captured by your cameras, to the SDK for processing.
• The image processing algorithms segment the exact rectangle (the car number plate location) by filtering out the other details in the images.
• Our SDK enhances the license plate image by adjusting brightness and contrast, the angle of the plate, and sharpens the blurred text, while also removing glare and reflections before recognition.
• Our system features AI capabilities to break down the number plate image into individual characters and convert the characters on the number plate into machine-readable text.
• The SDK then applies region-specific logic and rules to validate the regional attributes, minimizing false readings and improving accuracy.
• Then, the system provides the recognized number plate output in a structured, developer-friendly format (JSON or XML). Developers can utilize this output for various purposes.

Applications of the Car Plate Recognition System

Parking & Access Control

Developers can effectively utilize the LPR software to recognize car license plates and allow or restrict vehicle entry to stipulated premises. Automatically logging vehicle details can help in parking control. Additionally, the SDK can also help with automatic parking invoice generation.

Traffic Enforcement

• The SDK makes it easier to recognize vehicles crossing red signals.
• The number plate recognition software helps analyze number plates and check them against a police database.
• Traffic enforcement authorities can track overspeeding vehicles and issue warnings to prevent mishaps and accidents.

Smart City & Surveillance

As discussed earlier, the vehicle plate recognition system makes a significant contribution to traffic management, law enforcement, and public safety. LPR can empower innovative parking systems to manage payments automatically based on vehicle entry and exit logs—cashless toll collection and congestion zone pricing help in reducing bottlenecks.

Tolling & Transportation

The plate number recognition system helps prevent long queues at toll plazas. The system simplifies the implementation of an electronic toll collection system. Similarly, it helps regulate vehicle traffic in a large area through real-time insights.
