Object detection models can identify and classify various objects in the field, such as crops, weeds,
and pests. This information can be used to optimize resource allocation, reduce chemical usage, and
improve overall crop yield. For example, farmers can use object detection to pinpoint areas of a field
that require additional irrigation or pest control, allowing for targeted interventions rather than
blanket treatments.
By integrating object detection and computer vision into smart farming practices, farmers can enhance
productivity, reduce costs, and promote sustainable agriculture. These technologies enable real-time
monitoring and analysis, empowering farmers to make data-driven decisions that improve crop health and
yield while minimizing environmental impact.
How to detect and track objects on video
Object detection is a computer vision task that involves identifying and locating objects within an
image or video. It has numerous applications, including surveillance, autonomous vehicles, and robotics.
In this tutorial, we will demonstrate how to use the YOLOv8 object detection model to detect objects in
a video using the Abraia Vision SDK.
1. Install the Abraia Vision SDK
You can install the package on Windows, Mac, and Linux:
python -m pip install -U abraia
2. Load and run the object detection model
Import the "Model" and "Tracker" class from the inference module and load the "yolov8n" detection model.
Then use the "run" method from the model and the "Video" class to detect the objects in the frames.
To show the results on the image, simple use the "render_results" function.
from abraia.inference import Model, Tracker
from abraia.utils import Video, render_results
model = Model("multiple/models/yolov8n.onnx")
video = Video('images/people-walking.mp4')
tracker = Tracker(frame_rate=video.frame_rate)
for frame in video:
results = model.run(frame, conf_threshold=0.5, iou_threshold=0.5)
results = tracker.update(results)
frame = render_results(frame, results)
video.show(frame)
You can even run the model directly on the camera stream, just use "Video(0)" to use your webcam.
3. Record the YOLOv8 detection results on video
To record the output video, you just need to add the output parameter when you declare the video
object, and use the "write" method from video, instead of "show".
from abraia.inference import Model, Tracker
from abraia.utils import Video, render_results
model = Model("multiple/models/yolov8n.onnx")
video = detect.Video('people-walking.mp4', output='people-detected.mp4')
tracker = Tracker(frame_rate=video.frame_rate)
for frame in video:
results = model.run(frame, conf_threshold=0.5, iou_threshold=0.5)
results = tracker.update(results)
frame = render_results(frame, results)
video.write(frame)
Congratulations! You have successfully run the "yolov8n" object detection model on a video. This tutorial
provides a basic overview, and you can further explore advanced features, optimize your model, and fine-tune
parameters based on your specific use case.
