The Mechanics of Number Plate Recognition in Car Parks
Automatic License Plate Recognition (ALPR) systems are continuously improving car park management by making vehicle tracking and access control seamless and efficient. This technology is part of a broader evolution in transportation, dating back to the first license plates, introduced in 1893 in France, to help authorities identify vehicles on public roads.
Today, more than 1.4 billion vehicles worldwide rely on license plates, and with increasing numbers, ALPR technology has become critical. It boosts efficiency by reducing wait times, enhancing security, and providing data insights, benefiting both operators and customers.
The rise of AI-powered ALPR systems enables car parks to automate processes, lower operational costs, and improve customer experiences. With a single camera capturing data in real time, modern ANPR systems have become indispensable for managing vehicle traffic in urban settings.
How ANPR Works in Car Parks
Automatic Number Plate Recognition (ANPR) systems utilize a blend of hardware and software to streamline car park management. These systems are designed to automatically capture, process, and analyze vehicle license plates as cars enter or exit the parking area, improving overall efficiency and security.

Key Components:
High-Resolution Cameras: ANPR systems use specialized cameras placed at key entry and exit points. These cameras are optimized to capture clear images of vehicle plates, even in low-light or adverse weather conditions.
Optical Character Recognition (OCR): Once the image of the plate is captured, the system’s OCR technology converts it into machine-readable text. OCR algorithms analyze the image to identify the characters on the license plate, ensuring accurate data conversion for further processing.
AI-Powered Analysis: Modern ANPR systems, like Sighthound ALPR+, employ artificial intelligence to enhance accuracy and speed. AI analyzes multiple streams of data, ensuring quick and reliable recognition even when faced with challenges like dirty plates, diverse plate formats, or fast-moving vehicles.
These core components work together to automate vehicle tracking and streamline operations within car parks, offering not only operational efficiency but also enhanced security through real-time monitoring.
Benefits of Using ALPR in Car Parks
Implementing an ALPR system in car parks brings a variety of benefits that enhance both operational efficiency and user experience.

Increased Efficiency: ALPR systems automate the entire entry and exit process, reducing the need for manual intervention. Cars are identified in real-time, allowing for smoother traffic flow and less congestion at peak hours.
Enhanced Security: By capturing and analyzing license plates, ALPR provides real-time vehicle monitoring. This added layer of security ensures that unauthorized vehicles can be flagged, improving the safety of the car park.
Improved Data Insights: ALPR systems can track vehicle patterns, offering valuable insights into customer behavior. This data can help optimize parking space usage and enable predictive planning. Some systems, like Sighthound ALPR+, even offer MMCG (Make, Model, Color, Generation) recognition, allowing operators to gather more detailed data about the vehicles on-site in a subtle yet powerful way.
Use Cases for ALPR in Car Parks:
Retail Centers: ALPR helps streamline vehicle access for frequent shoppers, reducing wait times and enhancing the overall customer experience.
Office Complexes: ALPR automates entry for authorized employees and visitors, ensuring secure access while maintaining efficient traffic flow.
Airports: With a high volume of daily traffic, ALPR ensures that cars are quickly identified and tracked, making parking management seamless during busy periods.
The Role of AI in Modern ALPR Systems
Artificial intelligence (AI) plays a pivotal role in advancing the accuracy and efficiency of ALPR systems. AI-driven models enable these systems to detect and interpret plates with remarkable precision, even in challenging conditions like poor lighting or obscured plates.
For example, Sighthound ALPR+ leverages advanced machine learning to recognize license plates from various regions and formats. AI continuously learns from new data, ensuring that it adapts to different languages, alphabets, and even complex environments such as busy urban centers or high-speed highways.
In large airport car parks, where hundreds of vehicles move rapidly, AI-powered ALPR ensures smooth traffic flow by identifying cars instantly, regardless of weather or speed.
Similarly, smart city initiatives use AI to manage parking spaces and track traffic patterns in real time, optimizing urban mobility.
AI makes ALPR systems smarter, faster, and more reliable, resulting in higher accuracy and fewer errors in recognizing and processing vehicle data.
Common Challenges Solved by AI in ALPR Systems
While traditional ALPR systems may struggle with various challenges, Sighthound ALPR+ is trained on advanced AI models to overcome these obstacles with precision and efficiency. Here's how AI handles common problems:
Poor lighting or bad weather conditions: AI adapts to low-light or rainy environments, ensuring license plates are clearly captured, regardless of external conditions.
