大家好，我是Java1234_小锋老师，分享一套锋哥原创的人脸识别 智能考勤系统(深度学习+OpenCV DNN+FastAPI+Vue3)

项目介绍

随着深度学习与计算机视觉技术的快速发展，人脸识别逐渐成为身份认证与智能考勤领域的重要手段。传统考勤方式普遍存在代打卡、效率低、统计不便等问题，难以满足现代企事业单位精细化管理的需要。本文围绕“带人脸识别的智能考勤系统设计与实现”这一课题，设计并实现了一套前后端分离的智能考勤系统。系统后端采用 Python 语言与 FastAPI 框架构建 RESTful 接口服务，使用 SQLAlchemy 访问 MySQL 数据库；前端采用 Vue3、Element Plus、Pinia、Axios 与 ECharts 实现管理后台与刷脸打卡页面；人脸识别核心基于 OpenCV DNN 模块，结合 YuNet 人脸检测模型与 SFace 人脸识别模型，完成人脸定位、对齐、128 维特征提取与余弦相似度比对。系统实现了管理员登录与个人中心、部门岗位员工班次管理、人脸库注册、刷脸签到签退、考勤状态自动判定、请假加班审批、识别日志查询以及首页数据统计等功能。测试结果表明，系统运行稳定，识别流程清晰，能够有效提升考勤管理效率，具有较好的实用价值与推广意义。
