A Lightweight Deep Learning Framework for License Plate Detection in Complex Environments
摘要
Automatic License Plate Recognition (ALPR) is crucial for modern Intelligent Transportation Systems (ITS), but previous models like YOLOv8 face limitations in efficiency for real-time deployment on edge devices. To address this, our study proposes an ALPR system combining the advanced YOLOv12 model with EasyOCR, validated on a custom dataset of 8,397 diverse license plate images. Comparative analysis demonstrates YOLOv12’s superiority, with its lightweight Yolov12n variant achieving a higher mAP50–95 score (0.756) than Yolov8n (0.746), indicating enhanced localization accuracy. This study’s key contribution is providing a benchmark that confirms YOLOv12’s architectural advancements are not only for accuracy but are pivotal for enabling high-performance, real-time ALPR deployment. The findings establish YOLOv12 as a more effective and efficient solution for resource-constrained systems.
