🚀 Quick Start

Prerequisites

• Python 3.8 or higher
• 4GB+ RAM (8GB recommended)
• Webcam or video file for testing

Installation

1. Clone the repository

   git clone https://github.com/shubham333k/SmartPark-AI.git
   cd SmartPark-AI

2. Create virtual environment

   python -m venv venv
   
   # Windows
   venv\Scripts\activate
   
   # macOS/Linux
   source venv/bin/activate

3. Install dependencies

   pip install -r requirements.txt

4. Download YOLO model (automatic on first run)

   # Or manually download to models/ directory:
   # - yolov8n.pt (fastest)
   # - yolov8s.pt (balanced)
   # - yolo11n.pt (latest)

💻 Usage

Web Application (Recommended)

Launch the Streamlit dashboard:

streamlit run src/app.py

The app will open in your browser at http://localhost:8501

Workflow:

1. Configure YOLO model and confidence threshold in sidebar
2. Upload a parking lot video (MP4, AVI, MOV)
3. Preview and confirm auto-generated parking slots
4. Click "Start Processing" to analyze the video
5. View real-time occupancy metrics and charts
6. Download annotated video and CSV report

Command Line Demo

For quick testing without the web interface:

# Auto-generate slots and process video
python src/demo.py --video samples/parking_lot.mp4 --save

# Use custom slot configuration
python src/demo.py --video samples/parking_lot.mp4 --slots data/parking_slots.json --model yolov8s.pt

---

⚙️ Configuration

Parking Slot Layout

Option 1: Auto-Grid (Default)

• Automatically generates rectangular slots in a grid pattern
• Configure rows/columns via the sidebar

Option 2: Custom JSON Create a JSON file defining polygon coordinates:

{
  "slots": [
    {
      "slot_id": 1,
      "polygon": [
        [100, 200], [250, 200], [250, 280], [100, 280]
      ]
    }
  ]
}

Model Selection

Model	Speed	Accuracy	Use Case
yolov8n.pt	⚡ Fastest	Good	Real-time processing
yolov8s.pt	🚀 Fast	Better	Balanced performance
yolo11n.pt	⚡ Fast	Best	Latest architecture

📊 Performance Benchmarks

Tested on CPU (Intel i5-1240P / AMD Ryzen 5):

Resolution	Model	FPS	Accuracy*
640x480	YOLOv8n	25-30	85%
1280x720	YOLOv8n	15-20	88%
1280x720	YOLOv8s	10-15	91%
1920x1080	YOLOv8n	8-12	87%

*Accuracy = Occupancy detection accuracy with 0.3 overlap threshold

🔧 Advanced Configuration

Environment Variables

# Optional: Set model download directory
export SMARTPARK_MODEL_DIR="./models"

# Optional: Disable EasyOCR for faster processing
export SMARTPARK_DISABLE_OCR="1"

Custom Vehicle Classes

Modify DetectionConfig in src/utils.py to detect different vehicle types:

vehicle_classes: List[int] = [2, 3, 5, 7]  # COCO: car, motorcycle, bus, truck
class_names: Dict[int, str] = {
    2: "Car",
    3: "Motorcycle",
    5: "Bus",
    7: "Truck"
}
