1、安装Howdy: howdy项目地址
sudo add-apt-repository ppa:boltgolt/howdy sudo apt update sudo apt install howdy
2、添加自己的face
sudo howdy add
报错：
Enter a label for this new model [Initial model] (max 24 characters): tiger Camera path is not configured correctly, please edit the 'device_path' config value. Exception ignored in: <bound method VideoCapture.__del__ of <recorders.video_capture.VideoCapture object at 0x7f6bc5be02b0>> Traceback (most recent call last): File "/lib/security/howdy/recorders/video_capture.py", line 55, in __del__ self.internal.release() AttributeError: 'VideoCapture' object has no attribute 'internal'
解决方案:
$ sudo apt-get install v4l-utils # 查看摄像头路径 $ v4l2-ctl --list-devices USB 2.0 Camera: USB Camera (usb-0000:03:00.0-14): /dev/video0 $ sudo howdy config # 接下来更改config中的device_path = /dev/video0
$ sudo howdy add Adding face model for the user tiger Enter a label for this new model [Initial model] (max 24 characters): tiger Please look straight into the camera Scan complete Added a new model to tiger
3、测试
打开一个terminal
$ sudo -i Identified face as tiger
$ sudo howdy test Opening a window with a test feed Press ctrl+C in this terminal to quit Click on the image to enable or disable slow mode Closing window
4、屏幕锁屏后，enter进入输密码界面，程序就会识别出人，直接解锁。
