摘要

Abstract

Emergency lanes are critical for ensuring timely access of rescue vehicles during traffic congestion

significantly reducing accident fatalities when kept unobstructed. This study proposes a robust license plate recognition (LPR) system for monitoring illegal occupation of highway emergency lanes. The method integrates YOLOv11-pose for precise four-corner detection and PaddleOCR (PP-OCRv5) for high-speed character recognition

achieving an average recognition time of less than 10 milliseconds per plate. The models are unified via ONNX for efficient inference and evaluated on real-world surveillance videos from the Changshen Expressway. Experimental results demonstrate high accuracy and strong robustness

achieving 98.79% recognition accuracy and reliable performance across diverse scenarios

including new energy vehicle plates and long-distance captures. The system effectively supports automated traffic violation detection.
