lpr's Introduction

lpr 一个实际场景下的中文车牌识别软件

该软件基于开源软件项目https://github.com/zeusees/HyperLPR 以及 https://github.com/zeusees/Mobilenet-SSD-License-Plate-Detection 开发。

支持国内蓝、黄、绿、警单行车牌的识别,车牌定位支持haar级联定位和ssd定位,车牌识别支持端到端字符识别。

识别准确率95%,性能:普通笔记本电脑,3fps(cpu),10fps(intel gpu)。

使用

直接克隆或下载项目。

项目使用pycharm,python3.7 64位版, window10 64位版开发,开发环境配置:

  1. 安装anaconda3

  2. pip install tensorflow

  3. pip install keras

  4. pip install opencv-python

  5. 项目解压后,可以在cmd窗口,切换路径到项目路径下,执行: python lprcmd.py 或者 python lpr.py --video=test.mp4

主要项目文件说明

lprcmd.py:haar车牌定位加端到端车牌字符识别,命令行工具,输入是指定目录下(默认是test-imgs)的车牌图片,输出为指定目录下(默认是test-results)的识别结果文件。

lprssd.py:ssd车牌定位加端到端车牌字符识别,命令行工具,输入是指定目录下的车牌图片,输出为指定目录下的识别结果文件。

lpr.py:识别视频流中车牌的命令行代码,输入是图片或视频流,默认输出是项目路径下的识别图片或视频。

lprmix.py:混合了ssd和haar车牌定位的算法,在cpu下可以取得更好的识别准确率和性能。

HyperLprGUI.py: 展示车牌图片识别的图形界面程序。
