3/9 - Advance Face Recognition Student Attendance System Project in Python With Mysql database

Introduction

This tutorial will guide you through creating an advanced Face Recognition Student Attendance System using Python, OpenCV, Tkinter, and MySQL. This project allows real-time face detection, manages student data, takes attendance, and generates reports. By the end of this tutorial, you will have a functional attendance system that utilizes facial recognition technology.

Step 1: Setting Up Your Environment

1. Install Necessary Software

   • Download and install Visual Studio Code.
   • Download and install MySQL.
   • Make sure you have Python installed on your system.

2. Install Required Libraries

   • Open a terminal (or command prompt) and run the following commands to install the necessary Python libraries:

     pip install opencv-python
     pip install mysql-connector-python
     pip install tkinter
     

Step 2: Creating the Database

1. Open MySQL Workbench

   • Create a new database for your project. Use the following SQL command:

     CREATE DATABASE student_attendance;
     

2. Create Tables

   • Create a table for storing student information:

     CREATE TABLE students (
         id INT AUTO_INCREMENT PRIMARY KEY,
         name VARCHAR(100),
         photo BLOB
     );
     

   • Create a table for attendance records:

     CREATE TABLE attendance (
         id INT AUTO_INCREMENT PRIMARY KEY,
         student_id INT,
         attendance_date DATE,
         FOREIGN KEY (student_id) REFERENCES students(id)
     );
     

Step 3: Building the GUI

1. Set Up Tkinter

   • Create a new Python file (e.g., attendance_system.py).
   • Import necessary libraries:

     import tkinter as tk
     from tkinter import messagebox
     

2. Design the Main Window

   • Initialize the Tkinter window:

     root = tk.Tk()
     root.title("Student Attendance System")
     

3. Add Widgets

   • Add buttons for various functionalities (e.g., Student Management, Take Attendance):

     btn_manage_students = tk.Button(root, text="Manage Students", command=manage_students)
     btn_manage_students.pack()
     

Step 4: Implementing Face Recognition

1. Capture and Train Photos

   • Use OpenCV to capture images from a webcam:

     import cv2
     
     def capture_photos(student_id):
         cam = cv2.VideoCapture(0)
         while True:
             ret, frame = cam.read()
             cv2.imshow("Capture Photo", frame)
             if cv2.waitKey(1) & 0xFF == ord('q'):
                 break
         cam.release()
         cv2.destroyAllWindows()
     

2. Train the Model

   • Use the captured images to train your face recognition model. Implement the training logic using OpenCV's face recognition algorithms.

Step 5: Taking Attendance

1. Detect Faces in Real-Time

   • Implement real-time face detection in your attendance function:

     def take_attendance():
         # Load the face detection model
         # Loop for capturing video and detecting faces
     

2. Log Attendance

   • When a face is recognized, log the attendance in the MySQL database.

Step 6: Generating Attendance Reports

1. Create Report Functionality
   • Implement functionality to generate attendance reports in Excel format using libraries like pandas:

     import pandas as pd
     
     def generate_report():
         # Query attendance data from MySQL and save it as an Excel file
     

Conclusion

You have now set up an advanced Face Recognition Student Attendance System using Python, Tkinter, OpenCV, and MySQL. This system allows for real-time face detection, student management, and attendance tracking. Next steps could include improving the GUI, adding more features like notifications, or deploying the application.
