📏 Smart Object Size Estimator

An AI-powered web application that estimates real-world sizes of objects in images using depth estimation and segmentation.

🚀 Features

• —AI-Powered Detection: Uses Depth Anything V2 for depth estimation and SAM for object segmentation
• —Reference Object System: Click on any detected object and specify its known size to calibrate measurements
• —Camera Presets: Pre-configured settings for common smartphones (iPhone, Samsung, Google Pixel)
• —Real-time Processing: Interactive interface with immediate feedback
• —Robust Scaling: Works with images of any size and format

🛠️ How to Use

1. 1.Upload an Image: Choose any photo containing objects you want to measure
2. 2.Select Camera Type: Pick your device from presets or use custom focal length values
3. 3.Process Image: Click "Process Image" to detect objects (they'll be numbered and colored)
4. 4.Set Reference: Select an object you know the size of and enter its dimensions
5. 5.Calculate Sizes: Get measurements of all detected objects!

📷 Camera Settings

The app includes presets for:

• —iPhone 12/13/14 (Main & Ultra Wide cameras)
• —Samsung Galaxy S21/S22
• —Google Pixel 6/7
• —Generic Smartphone
• —Custom (manual focal length input)

�� Tips for Best Results

• —Use good lighting and avoid harsh shadows
• —Ensure objects are clearly visible and well-separated
• —Choose a reference object with a known precise dimension
• —Take photos perpendicular to objects when possible
• —For best accuracy, use camera-specific presets

🔧 Technical Details

• —Depth Model: Depth Anything V2 (ViT-Small)
• —Segmentation: Segment Anything Model (SAM)
• —Interface: Gradio web interface
• —Processing: Automatic image scaling and robust preprocessing

📚 Dependencies

All required packages are listed in requirements.txt. Key dependencies:

• —Gradio for web interface
• —PyTorch for model inference
• —OpenCV for image processing
• —Matplotlib for visualizations

🚀 Deployment

This app is designed to run on Hugging Face Spaces. Simply:

1. 1.Upload all files to a new HF Space
2. 2.Ensure the model weights are properly downloaded
3. 3.The app will auto-launch with Gradio

🎯 Use Cases

• —E-commerce: Product dimension verification
• —Interior Design: Furniture and room measurements
• —Manufacturing: Quality control and inspection
• —Education: Physics and measurement exercises
• —Daily Life: Measuring objects without a ruler

⚠️ Limitations

• —Accuracy depends on camera calibration
• —Works best with well-lit, clear images
• —Small or very thin objects may not segment well
• —Depth estimation quality affects final measurements
