🚀 Quick Start

# One command to run (All-in-One image, no downloads needed!)
docker run -d --name depth-pro --gpus all -p 8500:8500 neosun/depth-pro:latest

# Open browser
open http://localhost:8500

📦 Installation

Prerequisites

• Docker 24.0+ with NVIDIA Container Toolkit
• NVIDIA GPU with 8GB+ VRAM (16GB+ recommended)
• CUDA 12.1 compatible driver

Method 1: Docker Run (Recommended)

All-in-One image includes model weights (~5GB), no additional downloads required!

# Pull and run (model included in image)
docker run -d \
  --name depth-pro \
  --gpus all \
  -p 8500:8500 \
  -e GPU_IDLE_TIMEOUT=60 \
  neosun/depth-pro:latest

Method 2: Docker Compose

# Create docker-compose.yml
cat > docker-compose.yml << 'EOF'
services:
  depth-pro:
    image: neosun/depth-pro:latest
    container_name: depth-pro
    ports:
      - "8500:8500"
    environment:
      - GPU_IDLE_TIMEOUT=60
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]
    restart: unless-stopped
EOF

# Start service
docker compose up -d

Method 3: Local Development

# Create conda environment
conda create -n depth-pro python=3.9 -y
conda activate depth-pro

# Install dependencies
pip install -e .
pip install flask flask-cors flasgger gunicorn

# Download model
source get_pretrained_models.sh

# Run server
python app.py

📖 Usage

Web Interface

Visit http://localhost:8500 for the interactive UI:

1. Upload an image (JPG/PNG/WebP/HEIC)
2. Select colormap (Turbo, Viridis, Plasma, etc.)
3. Optionally set manual focal length
4. Click "Process" and download results

REST API

Depth Estimation

curl -X POST http://localhost:8500/api/predict \
  -F "file=@image.jpg" \
  -F "colormap=turbo" \
  -F "focal_length=1000"

Response:

{
  "task_id": "abc12345",
  "focal_length_px": 1000.0,
  "min_depth_m": 0.5,
  "max_depth_m": 10.2,
  "mean_depth_m": 3.4,
  "image_size": "1920x1080",
  "depth_image_base64": "...",
  "download_jpg": "/api/download/abc12345/color.jpg",
  "download_npz": "/api/download/abc12345/depth.npz",
  "download_16bit": "/api/download/abc12345/depth16.png"
}

GPU Status

curl http://localhost:8500/api/gpu/status

Release GPU Memory

curl -X POST http://localhost:8500/api/gpu/offload

API Documentation

MCP Server (for AI Assistants)

Add to your Claude Desktop config:

{
  "mcpServers": {
    "depth-pro": {
      "command": "docker",
      "args": ["exec", "-i", "depth-pro", "python3", "mcp_server.py"]
    }
  }
}

Available MCP tools:

• estimate_depth - Process single image
• batch_estimate_depth - Process multiple images
• get_gpu_status - Check GPU status
• release_gpu - Free GPU memory

🛠️ Tech Stack

• Model: Apple Depth Pro (DINOv2 + Multi-scale ViT)
• Backend: Flask + Gunicorn
• Frontend: Vanilla JS + Modern CSS
• Container: Docker + NVIDIA Container Toolkit
• GPU: PyTorch + CUDA 12.1

📝 Limitations

• Far-field scenes (>20m) may have inaccurate absolute depth values
• Best suited for indoor and close-range outdoor scenes
• Relative depth ordering is generally reliable even for far scenes
