Elderly Monitoring with Pose Detection: Modularized Code for Enhanced Functionality

This Python code implements an elderly monitoring system that utilizes Mediapipe's pose detection to analyze posture and movement in real-time. To enhance code organization and reusability, the core pose detection logic has been modularized into a separate file. Here's a breakdown of the process and benefits:

Modularization

1. Create a Separate File: Create a new Python file named 'pose_detection.py' in the same directory as your main script.

2. Move Pose Detection Code: Transfer the following code block from your main script to the newly created 'pose_detection.py' file:

import cv2
import mediapipe as mp
import numpy as np

# Function to calculate angle between three points
def calculate_angle(a, b, c):
    a = np.array(a)
    b = np.array(b)
    c = np.array(c)
    radians = np.arctan2(c[1] - b[1], c[0] - b[0]) - np.arctan2(a[1] - b[1], a[0] - b[0])
    angle = np.abs(radians * 180.0 / np.pi)
    if angle > 180.0:
        angle = 360 - angle
    return angle

mp_drawing = mp.solutions.drawing_utils
mp_pose = mp.solutions.pose

# Function to perform pose detection and analysis
def detect_pose(cap):
    # ... rest of the pose detection code ...

3. Import the Module: In your main script, import the 'pose_detection' module using:

from pose_detection import calculate_angle, detect_pose

4. Use the Functions: Now, you can directly use the calculate_angle and detect_pose functions from the pose_detection module in your main script.

Benefits of Modularization:

• Organization: Separates the pose detection logic into a dedicated file, making your main script cleaner and easier to understand.

• Reusability: The pose_detection module can be reused in other projects that require pose analysis.

• Maintainability: Changes to the pose detection logic can be made directly in the pose_detection.py file, without affecting the main script.

Example Usage in Main Script:

# ... your main script code ...

# Use the imported functions
angle = calculate_angle(left_eye, left_hip, left_heel)

# Call the detect_pose function
det_pose(cap)

# ... rest of your main script code ...

This modular approach improves code structure and facilitates future updates, making the elderly monitoring system more efficient and adaptable.
