TrackZone using Ultralytics YOLO11

What is TrackZone?

TrackZone specializes in monitoring objects within designated areas of a frame instead of the whole frame. Built on Ultralytics YOLO11, it integrates object detection and tracking specifically within zones for videos and live camera feeds. YOLO11's advanced algorithms and deep learning technologies make it a perfect choice for real-time use cases, offering precise and efficient object tracking in applications like crowd monitoring and surveillance.

Advantages of Object Tracking in Zones (TrackZone)

• Targeted Analysis: Tracking objects within specific zones allows for more focused insights, enabling precise monitoring and analysis of areas of interest, such as entry points or restricted zones.
• Improved Efficiency: By narrowing the tracking scope to defined zones, TrackZone reduces computational overhead, ensuring faster processing and optimal performance.
• Enhanced Security: Zonal tracking improves surveillance by monitoring critical areas, aiding in the early detection of unusual activity or security breaches.
• Scalable Solutions: The ability to focus on specific zones makes TrackZone adaptable to various scenarios, from retail spaces to industrial settings, ensuring seamless integration and scalability.

How can I use TrackZone in Python with Ultralytics YOLO11?

With just a few lines of code, you can set up object tracking in specific zones, making it easy to integrate into your projects.

import cv2

from ultralytics import solutions

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))

# Define region points
region_points = [(150, 150), (1130, 150), (1130, 570), (150, 570)]

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

# Init trackzone (object tracking in zones, not complete frame)
trackzone = solutions.TrackZone(
    show=True,  # display the output
    region=region_points,  # pass region points
    model="yolo11n.pt",
)

# Process video
while cap.isOpened():
    success, im0 = cap.read()
    if not success:
        print("Video frame is empty or video processing has been successfully completed.")
        break
    results = trackzone(im0)
    video_writer.write(results.plot_im)

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

How do I configure the zone points for video processing using Ultralytics TrackZone?

Configuring zone points for video processing with Ultralytics TrackZone is simple and customizable. You can directly define and adjust the zones through a Python script, allowing precise control over the areas you want to monitor.

# Define region points
region_points = [(150, 150), (1130, 150), (1130, 570), (150, 570)]

# Initialize trackzone
trackzone = solutions.TrackZone(
    show=True,  # display the output
    region=region_points,  # pass region points
)
