Introduction
|
|
************
|
|
|
|
Detect and recognize single/multi-faces from camera;
|
|
|
|
调用摄像头进行人脸识别，支持多张人脸同时识别;
|
|
|
|
|
|
#. 摄像头人脸录入 / Face register
|

|
|
|
|
请不要离摄像头过近，人脸超出摄像头范围时会有 "OUT OF RANGE" 提醒 /
|
|
Please do not too close to the camera, or you can't save faces with "OUT OF RANGE" warning;

#. 提取特征建立人脸数据库 / Generate database from images captured
|
|
#. 利用摄像头进行人脸识别 / Face recognizer
|
|
|
|
当单张人脸 / When single-face:

|
|
:align: center
|
|
|
|
当多张人脸 / When multi-faces:
|
|
|
|
一张已录入人脸 + 未录入 unknown 人脸:
|
|
|
|
.. image:: introduction/face_reco_two_people.png
|
|
:align: center
|
|
|
|
同时识别多张已录入人脸:

|
|
:align: center
|
|
|
|
** 关于精度 / About accuracy:
|
|
|
|
* When using a distance threshold of ``0.6``, the dlib model obtains an accuracy of ``99.38%`` on the standard LFW face recognition benchmark.

Steps
|
|
*****
|
|
|
|
#. 下载源码 / Download from website or via GitHub Desktop in windows, or clone repo in Ubuntu
|
|
|
|
.. code-block:: bash
|
|
|
|
git clone https://github.com/coneypo/Dlib_face_recognition_from_camera
|
|
|
|
#. 进行 face register / 人脸信息采集录入
|
|
|
|
.. code-block:: bash
|
|
|
|
python3 get_face_from_camera.py
|
|
|
|
#. 提取所有录入人脸数据存入 features_all.csv
|
|
|
|
.. code-block:: bash
|
|
|
|
python3 get_features_into_CSV.py
|
|
|
|
#. 调用摄像头进行实时人脸识别
|
|
|
|
.. code-block:: bash
|
|
|
|
python3 face_reco_from_camera.py
|
|
|
|
|
|
About Source Code
|
|
*****************
|
|
|
|
Python 源码介绍如下:
|
|
|
|
#. get_face_from_camera.py:
|
|
|
|
进行 Face register / 人脸信息采集录入
|
|
|
|
* 请注意存储人脸图片时，矩形框不要超出摄像头范围，要不然无法保存到本地;
|
|
* 超出会有 "out of range" 的提醒;
|
|
|
|
|
|
#. get_features_into_CSV.py:
|
|
|
|
从上一步存下来的图像文件中，提取人脸数据存入CSV;
|
|
|
|
* 会生成一个存储所有特征人脸数据的 "features_all.csv"；
|
|
* size: n*128 , n means n people you registered and 128 means 128D features of the face
|
|
|
|
|
|
#. face_reco_from_camera.py:
|
|
|
|
这一步将调用摄像头进行实时人脸识别; / This part will implement real-time face recognition;
|
|
|
|
* Compare the faces captured from camera with the faces you have registered which are saved in "features_all.csv"
|
|
|
|
* 将捕获到的人脸数据和之前存的人脸数据进行对比计算欧式距离, 由此判断是否是同一个人;

Tips:
|
|
|
|
1. Windows下建议不要把代码放到 ``C:\``, 可能会出现权限读取问题
|
|
|
|
2. 代码最好不要有中文路径
|
|
|
|
3. 人脸录入的时候先建文件夹再保存图片, 先 ``N`` 再 ``S``
