# Parking Management using Ultralytics YOLOv8 🚀

## What is Parking Management System?

Parking management with [Ultralytics YOLOv8](https://github.com/ultralytics/ultralytics/) ensures efficient and safe parking by organizing spaces and monitoring availability. YOLOv8 can improve parking lot management through real-time vehicle detection, and insights into parking occupancy.

## Advantages of Parking Management System?

- **Efficiency**: Parking lot management optimizes the use of parking spaces and reduces congestion.
- **Safety and Security**: Parking management using YOLOv8 improves the safety of both people and vehicles through surveillance and security measures.
- **Reduced Emissions**: Parking management using YOLOv8 manages traffic flow to minimize idle time and emissions in parking lots.

## Parking Management System Code Workflow

### Selection of Points

!!! Tip "Point Selection is now Easy"

    Choosing parking points is a critical and complex task in parking management systems. Ultralytics streamlines this process by providing a tool that lets you define parking lot areas, which can be utilized later for additional processing.

- Capture a frame from the video or camera stream where you want to manage the parking lot.
- Use the provided code to launch a graphical interface, where you can select an image and start outlining parking regions by mouse click to create polygons.

!!! Warning "Image Size"

    Max Image Size of 1920 * 1080 supported

!!! Example "Parking slots Annotator Ultralytics YOLOv8"

    === "Parking Annotator"

        ```python
        from ultralytics import solutions

        solutions.ParkingPtsSelection()
        ```

- After defining the parking areas with polygons, click `save` to store a JSON file with the data in your working directory.

### Python Code for Parking Management

!!! Example "Parking management using YOLOv8 Example"

    === "Parking Management"

        ```python
        import cv2
        from ultralytics import solutions

        # Path to json file, that created with above point selection app
        polygon_json_path = "bounding_boxes.json"

        # Video capture
        cap = cv2.VideoCapture("Path/to/video/file.mp4")
        assert cap.isOpened(), "Error reading video file"
        w, h, fps = (int(cap.get(x)) for x in (cv2.CAP_PROP_FRAME_WIDTH, cv2.CAP_PROP_FRAME_HEIGHT, cv2.CAP_PROP_FPS))

        # Video writer
        video_writer = cv2.VideoWriter("parking management.avi", cv2.VideoWriter_fourcc(*"mp4v"), fps, (w, h))

        # Initialize parking management object
        management = solutions.ParkingManagement(model_path="yolov8n.pt")

        while cap.isOpened():
            ret, im0 = cap.read()
            if not ret:
                break

            json_data = management.parking_regions_extraction(polygon_json_path)
            results = management.model.track(im0, persist=True, show=False)

            if results[0].boxes.id is not None:
                boxes = results[0].boxes.xyxy.cpu().tolist()
                clss = results[0].boxes.cls.cpu().tolist()
                management.process_data(json_data, im0, boxes, clss)

            management.display_frames(im0)
            video_writer.write(im0)

        cap.release()
        video_writer.release()
        cv2.destroyAllWindows()
        ```
