Automated Number Plate Recognition (ANPR) cameras play a crucial role in modern traffic enforcement, security, and mobility management. But just how reliable are they? This question is often raised by both the general public and industry professionals who rely on this technology for various applications, from speed enforcement to vehicle tracking and access control.
To investigate this topic in depth, RTBF—a leading public service broadcaster that provides radio and television services to the French-speaking community of Belgium in Wallonia and Brussels—embarked on a fact-finding mission to uncover the truth about ANPR accuracy, efficiency, and reliability. As part of their research, they visited our offices to gain expert insights into the inner workings of ANPR technology and its real-world applications.
During their visit, we had the opportunity to explain the advanced technology behind ANPR systems, how they process vast amounts of data in real-time, and the measures in place to ensure high accuracy rates. Our specialists shared key information on:
How ANPR cameras capture and process license plate data
The role of artificial intelligence and machine learning in improving accuracy
Factors that influence ANPR performance, such as weather conditions and lighting
The importance of high-quality image processing in reducing false readings
The use of ANPR in traffic enforcement, tolling, and smart city applications
One of the key takeaways from the discussion was that ANPR technology has significantly evolved over the years, now boasting accuracy rates of over 98% under optimal conditions. By leveraging high-resolution cameras, infrared illumination, and sophisticated OCR (Optical Character Recognition) algorithms, modern ANPR systems can reliably detect and interpret license plates in various environments, even at high speeds or in challenging lighting conditions.
Of course, like any technology, ANPR is not infallible. Environmental factors such as extreme weather, dirt-covered plates, or certain font styles can sometimes lead to misreads. However, advancements in AI and continuous system improvements ensure that these limitations are minimized, making ANPR one of the most effective tools for traffic enforcement and vehicle identification.
