小編給大家分享一下Ubuntu中實現(xiàn)人臉識別登錄的案例分析，希望大家閱讀完這篇文章后大所收獲，下面讓我們一起去探討方法吧！

1、安裝Howdy: howdy項目地址

sudo add-apt-repository ppa:boltgolt/howdy
sudo apt update
sudo apt install howdy

2、添加自己的face

sudo howdy add

報錯：

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'

解決方案:

$ sudo apt-get install v4l-utils
# 查看攝像頭路徑
$ v4l2-ctl --list-devices
USB 2.0 Camera: USB Camera (usb-0000:03:00.0-14):
 /dev/video0
$ sudo howdy config
# 接下來更改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、測試

打開一個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、屏幕鎖屏后，enter進入輸密碼界面，程序就會識別出人，直接解鎖。

5、其它命令

Usage:

howdy [-U user] [-y] command [argument]
CommandDescription
addAdd a new face model for an user
clearRemove all face models for an user
configOpen the config file in your default editor
disableDisable or enable howdy
listList all saved face models for an user
removeRemove a specific model for an user
snapshotTake a snapshot of your camera input
testTest the camera and recognition methods
versionPrint the current version number
