目录
一、项目简介
二、功能展示
1.人脸识别功能测试
2.识别并录入人脸及个人信息
3.数据库保存信息
4.考勤打卡
三、环境安装实例
1.下载python对应版本的dlib
2.安装opencv-python
3.安装face_recognition
4.安装pyqt5
5.安装mysqlclient
四、需要源码私信并call邮箱lij867967@gmail.com
本项目使用编程语言Python3.8,anaconda,开发工具pycharm,数据库MySQL5.7。
技术应用:开源计算机视觉库opencv-python,开源人脸识别库face_recognition,使用PyQt5制作人脸识别以及考勤界面,dlib人脸检测技术,以及MySQLdb连接数据库。
功能介绍:
第一步:录入,进入录入界面。调用摄像头检测识别人脸、输入姓名学号,人脸照片保存在faces文件夹中,姓名学号保存在数据库中。
第二步:考勤,进入考勤界面。调用摄像头进行人脸识别,摄像头识别出人脸和人脸对应的名字。
这是从网上随便找了一张图片识别静态人脸,成功。

调用摄像头识别动态人脸,成功

上述功能代码如下:
def a1(): #加载图片 img=face_recognition.load_image_file("1.jpeg") #检测脸部位置 pos=face_recognition.face_locations(img) print("位置top,right,bottom,left",pos) for i in range(len(pos)): rect=pos[i] #绘制矩形 cv2.rectangle(img,(rect[3],rect[0]),(rect[1],rect[2]),(0,0,220),2) #显示窗口 cv2.imshow("",img) cv2.waitKey(0) def a2(): vd=cv2.VideoCapture(0) while True: #读取摄像头数据流 ok,frame=vd.read() #矩阵子集 facearea=frame[:,:,::-1] pos=face_recognition.face_locations(facearea) for(top,right,bottom,left) in pos: cv2.rectangle(frame,(left,top),(right,bottom),(0,200,0),2) cv2.imshow("",frame) cv2.waitKey(1) vd.release() cv2.destroyAllWindows()
此时人脸已经录入faces文件中,点击确定即可填写个人信息。
编辑
编辑填写好信息,点击保存,信息即保存到数据库。
编辑
此时刚刚输入的账号和姓名已经保存到faces文件中,如下
编辑(挡住了一点,但是能看到)
功能代码如下:

我使用的数据库可视化工具是Navicat12 for MySQL(也可以不用,mysql基本命令知道的话直接管理员cmd也可)
编辑
运行如下,此时摄像头一直在运行,绿色框框始终识别你的人脸(跟随你移动)
编辑
点击“请开始考勤”,开始考勤时间会直接显示在界面上
编辑
点击“请结束考勤”,结束考勤时间会存入数据库编辑
功能代码如下:

Anaconda!真的好用!
你想要的dlib版本这里都有
然后pip install dlib -........whl(install后面为你下载的dlib的文件名)
pip install Cmake
pip install opencv-python
pip install face_recognition
pip install pyqt5
pip install mysqlclient
至此,结束!
