🛏️ SleepGuard Pro - Advanced Sleep Monitoring System An AI-powered sleep monitoring system that uses standard IP cameras to provide medical-grade sleep analysis without wearable devices. ## ✨ Features ### Core Monitoring - **Real-time Sleep Detection** - Using YOLOv8 and MediaPipe for pose detection - **Breathing Analysis** - Contactless breathing rate monitoring - **Sleep Position Tracking** - Detect supine, prone, side positions - **Movement Detection** - Track restlessness and position changes - **Audio Analysis** - Snoring, sleep talking, and apnea detection ### Advanced Analytics - **Sleep Stage Classification** - REM/Non-REM detection - **Sleep Quality Score** - Comprehensive quality metrics - **Apnea Detection** - Identify breathing interruptions - **Environmental Monitoring** - Temperature, humidity, light tracking ### User Features - **Real-time Streaming** - WebSocket-based live monitoring - **Mobile App Support** - REST API for mobile integration - **Multi-person Tracking** - Monitor multiple people simultaneously - **Historical Data** - Long-term sleep pattern analysis - **Smart Alerts** - Customizable health notifications ## 🚀 Quick Start ### Prerequisites - Python 3.11+ - Docker & Docker Compose (optional) - IP Camera or Webcam - CUDA-capable GPU (optional, for better performance) ### Installation #### Method 1: Docker (Recommended) ```bash # Clone the repository git clone https://github.com/yourusername/sleep-monitor.git cd sleep-monitor # Configure settings cp config.yaml.example config.yaml # Edit config.yaml with your settings # Start all services docker-compose up -d # Access the application # API: http://localhost:8000 # Grafana: http://localhost:3000 # API Docs: http://localhost:8000/api/docs ``` #### Method 2: Local Installation ```bash # Clone the repository git clone https://github.com/yourusername/sleep-monitor.git cd sleep-monitor # Create virtual environment python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate # Install dependencies pip install -r requirements.txt # Download YOLOv8 model python -c "from ultralytics import YOLO; YOLO('yolov8n-pose.pt')" # Start services # Terminal 1 - Start InfluxDB docker run -d -p 8086:8086 influxdb:2.7-alpine # Terminal 2 - Start Redis docker run -d -p 6379:6379 redis:7-alpine # Terminal 3 - Start the application python api_service.py ``` ## 📋 Configuration Edit `config.yaml` to configure: ```yaml camera: source: 0 # Webcam (0) or IP camera URL resolution: width: 1920 height: 1080 sleep_detection: movement_threshold: 0.02 breathing_roi_size: 100 normal_breathing_rate: [12, 20] alerts: apnea_duration: 10 # seconds email: enabled: true smtp_server: "smtp.gmail.com" ``` ## 🔌 API Usage ### Authentication ```python import requests # Login response = requests.post( "http://localhost:8000/api/auth/login", json={"username": "user", "password": "pass"} ) token = response.json()["access_token"] ``` ### Start Monitoring ```python # Start session headers = {"Authorization": f"Bearer {token}"} response = requests.post( "http://localhost:8000/api/session/start", headers=headers ) session_id = response.json()["session_id"] ``` ### Real-time Streaming ```python import websocket import json def on_message(ws, message): data = json.loads(message) if data["type"] == "frame": # Process frame data print(f"Persons detected: {len(data['data']['persons'])}") elif data["type"] == "audio": # Process audio events print(f"Audio events: {data['events']}") ws = websocket.WebSocketApp( "ws://localhost:8000/ws/stream", on_message=on_message ) ws.run_forever() ``` ### Get Sleep Report ```python # Get daily report response = requests.get( "http://localhost:8000/api/reports/daily", headers=headers, params={"date": "2024-01-15"} ) report = response.json() print(f"Sleep quality: {report['sleep_quality']}") ``` ## 📊 Data Analysis ### Using Grafana 1. Access Grafana at `http://localhost:3000` 2. Login with `admin/admin` 3. Import dashboard from `grafana/dashboards/sleep-monitor.json` 4. View real-time and historical sleep data ### Using InfluxDB ```python from influxdb_client import InfluxDBClient client = InfluxDBClient( url="http://localhost:8086", token="your-token", org="sleep-monitor" ) query = ''' from(bucket: "sleep-data") |> range(start: -7d) |> filter(fn: (r) => r["_measurement"] == "sleep_data") |> mean() ''' result = client.query_api().query(query) ``` ## 🏗️ Architecture ``` ┌─────────────────┐ ┌─────────────────┐ │ IP Camera │────▶│ Video Processor│ └─────────────────┘ └────────┬────────┘ │ ┌─────────────────┐ ▼ │ Microphone │────▶┌─────────────────┐ └─────────────────┘ │ API Service │ └────────┬────────┘ │ ┌────────────────────────┼────────────────────┐ ▼ ▼ ▼ ┌───────────────┐ ┌──────────────┐ ┌──────────────┐ │ InfluxDB │ │ Redis │ │ MongoDB │ │ (Time Series) │ │ (Cache) │ │ (Documents) │ └───────────────┘ └──────────────┘ └──────────────┘ │ ▼ ┌───────────────┐ ┌──────────────┐ ┌──────────────┐ │ Grafana │ │ Mobile App │ │ Web App │ └───────────────┘ └──────────────┘ └──────────────┘ ``` ## 🔧 Development ### Project Structure ``` sleep-monitor/ ├── api_service.py # FastAPI main service ├── video_processor.py # Video processing module ├── audio_processor.py # Audio processing module ├── config.yaml # Configuration file ├── models/ # ML models ├── tests/ # Unit tests ├── docker-compose.yml # Docker orchestration └── requirements.txt # Python dependencies ``` ### Running Tests ```bash # Run all tests pytest # Run with coverage pytest --cov=. --cov-report=html # Run specific test pytest tests/test_video_processor.py ``` ### Adding New Features 1. Create feature branch 2. Implement feature with tests 3. Update documentation 4. Submit pull request ## 🚨 Troubleshooting ### Common Issues **Camera not detected:** ```bash # Check camera permissions ls -la /dev/video* # Add user to video group sudo usermod -a -G video $USER ``` **Audio not working:** ```bash # Install audio dependencies sudo apt-get install portaudio19-dev # Test audio python -m sounddevice ``` **GPU not utilized:** ```bash # Check CUDA installation nvidia-smi # Install PyTorch with CUDA pip install torch torchvision --index-url https://download.pytorch.org/whl/cu118 ``` ## 📈 Performance Optimization ### For Raspberry Pi / Edge Devices ```yaml # config.yaml optimizations video_processing: yolo_model: "yolov8n-pose.pt" # Use nano model skip_frames: 5 # Process every 5th frame confidence_threshold: 0.3 camera: resolution: width: 640 height: 480 fps: 15 ``` ### For High-Performance Servers ```yaml # config.yaml for servers video_processing: yolo_model: "yolov8x-pose.pt" # Use extra-large model skip_frames: 1 # Process every frame camera: resolution: width: 3840 height: 2160 fps: 60 ``` ## 📝 License This project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details. ## 🤝 Contributing Contributions are welcome!
