Graduation Project---Web-side Attendance System Based on Face Recognition

 

---

1. Prospect Summary

---

1.1, Background Introduction

1. This article is a comprehensive summary of my graduation project, involving programming codes of some important sections.

2. It is a web-based face recognition project, and I hope that students who have related needs can benefit from it.

3. Because I only learned the python language roughly in my sophomore year, and I missed the autumn recruits to prepare for the spring recruits, I completed it within one month starting in May.

4. Frameworks, etc. are all learned from scratch, most of the content is repeated, and the code is extremely unsuccinct. Please correct me if I find any mistakes.

Third, use the configuration

---

3.1, installation and configuration tutorial

• Pycharm crack installation & configuration tutorial

• Pycharm creates a Django project 

• Pycharm needs to reinstall some third-party libraries every time a new project is created.

• Pycharm import anaconda environment     PyCharm+Anaconda environment configuration  

• The download addresses for most libraries   look in the Python installation directory

3.2, package installation

• Note: The installation of packages pays attention to the version compatibility between each other, and the code writing is sometimes different for different versions.

• Method 1: In Anaconda Prompt: pip install library name -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com image acceleration

• Method 2: Download the .whl file, cd to the corresponding directory through the command line, and install   the download address of most libraries through pip

• Method 3: Anaconda Navigator installation: Click the green circle, select the second line on the left, environment, root, not installed, search for the corresponding package name, and install

• Notice:

  • When installing packages, pay attention to the version compatibility between each other, and the code writing is sometimes different for different versions.

  • urllib and urllib2 are merged in versions after Python3, the installation should be: pip install urllib3

  • It is best to specify 14/pip install tensorflow==1.15 to install tensorflow in Python3.7 version 

  • The Dlib version corresponding to Python3.7 needs to be 3.7, and most of the online versions are 3.6. The link is as follows

  • The haarcascades file corresponding to face detection Opencv

3.3, common command line operations

• Switch to E drive: E:

• Toggle previous: cd ..

• Switch to the specified path: cd pathname

• pip operation version update: python -m pip install --upgrade pip

• Force installation of the corresponding library: pip install --ignore-installed <library name>

• Check python version: python -V

• View the packages installed by anaconde: conda list

3.4, create a Django project

• Method 1: Create from the command line

  • pip install django==1.8.2 //Download the corresponding package 

  • Go to the corresponding directory, cmd, press Enter to open the command line (OR use **administrator to switch** to the appropriate directory)

  • django-admin startproject project name //Create a project, **cd project name**, go to the corresponding project

  • python manage.py startapp app // Create app, if pycharm needs venv\Scripts\activate

  • python manage.py runserver//start the project

• Method 2: Create a project through Pycharm

  • Open Pycharm, click file, select new project, click Django, Location is the created project location

  • Click File, click Settings, select Project interpreter, and the corresponding installed packages are displayed on the right:

    • Generally choose Anaconda, configure it, add   Pycharm and import the anaconda environment     PyCharm+Anaconda environment configuration  

    • In addition, you can create a separate project to place the configured package, and then create other projects to import the configuration of the project package.

3.5, environment configuration
