项目运行
需要先安装Python的相关依赖:pymysql,Django==3.2.8,pillow 使用pip install 安装
第一步:创建数据库
第二步:执行SQL语句,.sql文件,运行该文件中的SQL语句
第三步:修改源代码中的settings.py文件,改成自己的mysql数据库用户名和密码
第四步:运行命令:python manage.py runserver 8000
第五步:打开浏览器查看http://127.0.0.1:8000

系统介绍:
本系统是一款基于Python编程语言和OpenCV图像处理库开发的疲劳检测系统,旨在通过分析人脸图像来判断测试者的疲劳程度。系统通过检测测试者的眼睛闭合程度、眨眼频次以及面部表情来表征测试者的疲劳程度,并通过Mysql数据库存储和管理图像识别数据。
整体功能包含:
- 用户登录与注册
- 实时人脸图像捕捉与分析
- 疲劳程度评估与预警
- 数据存储与管理
前台模块:
- 登录/注册页面:用户可以进行系统登录或注册新账户
- 图片识别界面:用户可以通过摄像头进行实时人脸图像捕捉
- 照片分析界面:展示用户眼睛状态、打哈欠占比等疲劳分析数据
后台模块:
- 照片管理界面:管理用户上传的图像内容,包括删除异常图片
- 用户管理界面:修改用户信息,新增用户等操作
