Introduction to ANPR Software
Automatic Number Plate Recognition (ANPR) software has become a pivotal tool in modern traffic management, security, and surveillance. ANPR systems are designed to automatically capture and interpret vehicle license plates using digital imaging technology. This technology finds application across various sectors, including law enforcement, toll collection, parking management, and access control in private and public spaces.
Traditionally, ANPR systems relied on template matching algorithms, where the software would compare captured images to pre-stored characters templates. While effective to an extent, this approach had limitations in accuracy, especially in diverse and dynamic environmental conditions.
The Shift to Deep Learning-Based ANPR Software
Recent years have seen a significant shift in ANPR technology. The focus has moved from traditional template matching algorithms to more advanced deep learning-based approaches. Deep learning algorithms, a subset of machine learning, enable the software to learn and improve from experience. This shift brings about a notable enhancement in the accuracy of plate recognition, as deep learning algorithms can better handle variations in lighting, angles, plate obfuscation, and even diverse plate designs from different regions.
However, the adoption of deep learning technologies in ANPR systems demands higher computational power. Deep learning processes involve analyzing vast amounts of data and complex neural networks, which can be computationally intensive and time-consuming.
The Role of Modern GPUs in Enhancing ANPR Software
To address the computational demands of deep learning-based ANPR systems, the integration of modern Graphics Processing Units (GPUs) has become essential. GPUs are particularly adept at handling parallel processing tasks, making them ideal for deep learning applications. The use of GPUs in ANPR systems significantly accelerates the data processing speed, thereby enhancing the overall efficiency and responsiveness of the system.
Benchmarking INTERTRAFF’s ANPR SDK with Modern GPUs
To illustrate the impact of modern GPUs on ANPR software performance, we conducted a benchmark study using INTERTRAFF’s ANPR SDK across different hardware configurations. The results underscore the importance of choosing the right GPU for optimal performance:
1. GPU Intel Core i9-9900K 3.6 GHz: With an execution time of 17 milliseconds for the plate finder, this configuration demonstrates reliable performance, suitable for applications where rapid plate recognition is essential.
2. GPU GeForce GTX 1050 CUDA: Clocking in at 18 milliseconds, the GTX 1050, although slightly slower than the i9-9900K, still offers robust performance, representing a good balance between cost and speed for many ANPR applications.
3. GPU GeForce RTX 2080 CUDA: The RTX 2080 stands out with a remarkable execution time of just 7 milliseconds, showcasing the significant advantage of using high-end GPUs in processing the complex computations required by deep learning-based ANPR software.
