📏 Object Size Measurement Tool

A web application that measures real-world dimensions of objects in images using checkerboard calibration patterns.

🚀 Features

• —Automatic Calibration: Detects checkerboard patterns for accurate pixel-to-cm conversion
• —Object Detection: Automatically finds and measures multiple objects
• —Pattern Generator: Create custom calibration patterns
• —Real-time Results: Instant measurements with visual annotations
• —Export Results: Download measurements as text file

🛠️ How It Works

1. 1.Calibration: Uses a checkerboard pattern with known square dimensions
2. 2.Detection: OpenCV finds the pattern and calculates pixel-to-cm ratio
3. 3.Measurement: Detects objects and converts their pixel dimensions to real-world measurements

📋 Requirements

• —Python 3.8+
• —OpenCV
• —Streamlit
• —NumPy
• —Pillow

🎯 Usage

1. 1.Print a calibration pattern (or generate one in the app)
2. 2.Place it next to objects you want to measure
3. 3.Take a photo with both pattern and objects visible
4. 4.Upload to the app and enter the real square size
5. 5.Get instant measurements!

⚠️ Important Notes

• —Objects and calibration pattern must be at the same distance from camera
• —Better lighting improves detection accuracy
• —Pattern should be flat and clearly visible
