    # queue_region = [(20, 400), (1080, 400), (1080, 360), (20, 360), (20, 400)]  # Define queue polygon points

    # Init Queue Manager
    queue = solutions.QueueManager(
        show=True,  # Display the output
        model="yolo11n.pt",  # Path to the YOLO11 model file
        region=queue_region,  # Pass queue region points
        # classes=[0, 2],  # If you want to count specific classes i.e person and car with COCO pretrained model.
        # line_width=2,  # Adjust the line width for bounding boxes and text display
    )

    # Process video
    while cap.isOpened():
        success, im0 = cap.read()

        if success:

FAQ

How can I use Ultralytics YOLO11 for real-time queue management?

To use Ultralytics YOLO11 for real-time queue management, you can follow these steps:

1. Load the YOLO11 model with YOLO("yolo11n.pt").
2. Capture the video feed using cv2.VideoCapture.
3. Define the region of interest (ROI) for queue management.
4. Process frames to detect objects and manage queues.

Here's a minimal example:

import cv2

from ultralytics import solutions

cap = cv2.VideoCapture("path/to/video.mp4")
queue_region = [(20, 400), (1080, 400), (1080, 360), (20, 360)]

queue = solutions.QueueManager(
    model="yolo11n.pt",
    region=queue_region,
    line_width=3,
)

while cap.isOpened():
    success, im0 = cap.read()
    if success:
        out = queue.process_queue(im0)
        cv2.imshow("Queue Management", im0)
        if cv2.waitKey(1) & 0xFF == ord("q"):
            break

cap.release()
cv2.destroyAllWindows()
