背景及意义

智能车牌检测与识别系统通过使用最新的YOLOv8与PaddleOCR算法能够迅速、准确地在多种环境下实现实时车牌的检测和识别。本文基于YOLOv8深度学习框架，通过16770张图片，训练了一个进行车牌检测模型,可以检测蓝牌与绿牌,然后对检测到的车牌使用OCR识别技术，进行车牌的识别。最终基于此模型开发了一款带UI界面的车牌检测与识别系统，可用于实时检测与识别场景中的车牌，更方便进行功能的展示。该系统是基于python与PyQT5开发的，支持图片、视频以及摄像头进行目标检测与识别，并保存检测识别结果。本文提供了完整的Python代码和使用教程，给感兴趣的小伙伴参考学习，完整的代码资源文件获取方式见文末。
