face_recognition(face_recognition中文使用说明)号称是世界上最简单的开源人脸识别库,可以通过Python或命令行识别和操作人脸。本项目采用face_recognition开源库,利用网络摄像头(DroidCam,官网)实现人脸检测、人脸关键点提取、人脸识别对比、人脸识别之后在原图上标注姓名并语音播报识别成功后人的姓名,未识别的人实现报警提示。
1.安装dlib
dlib版本需要和Python版本相对应。由于我的Python版本是3.8.10,所以我去搜寻dlib-cp38。dlib版本如下:
dlib版本
如我将whl文件保存在 D:\data 中,则在命令行输入:
pip install D:\data\dlib-19.19.0-cp38-cp38-win_amd64.whl
1.安装face_recognition
使用pip安装(使用了国内镜像源),在命令行输入:
pip install face_recognition -i https://pypi.douban.com/simple
