# Queue Management using Ultralytics YOLOv8 🚀 |
|
|
|
## What is Queue Management? |
|
|
|
Queue management using [Ultralytics YOLOv8](https://github.com/ultralytics/ultralytics/) involves organizing and controlling lines of people or vehicles to reduce wait times and enhance efficiency. It's about optimizing queues to improve customer satisfaction and system performance in various settings like retail, banks, airports, and healthcare facilities. |

## Advantages of Queue Management? |
|
|
|
- **Reduced Waiting Times:** Queue management systems efficiently organize queues, minimizing wait times for customers. This leads to improved satisfaction levels as customers spend less time waiting and more time engaging with products or services. |
|
- **Increased Efficiency:** Implementing queue management allows businesses to allocate resources more effectively. By analyzing queue data and optimizing staff deployment, businesses can streamline operations, reduce costs, and improve overall productivity. |

|
### How can I use Ultralytics YOLOv8 for real-time queue management? |
|
|
|
To use Ultralytics YOLOv8 for real-time queue management, you can follow these steps: |
|
|
|
1. Load the YOLOv8 model with `YOLO("yolov8n.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: |
|
|
|
```python |
|
import cv2 |
|
|
|
from ultralytics import YOLO, solutions |
|
|
|
model = YOLO("yolov8n.pt") |
|
cap = cv2.VideoCapture("path/to/video.mp4") |
|
queue_region = [(20, 400), (1080, 404), (1080, 360), (20, 360)] |
|
|
|
queue = solutions.QueueManager( |
|
names=model.names, |
|
reg_pts=queue_region, |
|
line_thickness=3, |
|
fontsize=1.0, |
|
region_color=(255, 144, 31), |
|
) |
|
|
|
while cap.isOpened(): |
|
success, im0 = cap.read() |
|
if success: |
|
tracks = model.track(im0, show=False, persist=True, verbose=False) |
|
out = queue.process_queue(im0, tracks) |
|
cv2.imshow("Queue Management", im0) |
|
if cv2.waitKey(1) & 0xFF == ord("q"): |
|
break |
|
|
|
cap.release() |
|
cv2.destroyAllWindows() |
|
``` |

|
|
|
```python |
|
queue_region_airport = [(50, 600), (1200, 600), (1200, 550), (50, 550)] |
|
queue_airport = solutions.QueueManager( |
|
names=model.names, |
|
reg_pts=queue_region_airport, |
|
line_thickness=3, |
|
fontsize=1.0, |
|
region_color=(0, 255, 0), |
|
) |
|
``` |
