Use Cases

Overview

The OWL is designed for site-specific weed control in fallow fields. It uses computer vision to detect green vegetation against brown/bare soil backgrounds and triggers solenoids for targeted herbicide application.

Key Applications

• Spot spraying - Site-specific herbicide application

• Targeted tillage - Mechanical weed control

• Spot flaming - Thermal weed control

• Image data collection - Building training datasets for machine learning

Detection Algorithms

Algorithm	Sensitivity	Description
exg	Most sensitive	Excess Green - more false positives
exhsv	Balanced	Combined ExG and HSV - default
hsv	Least sensitive	HSV thresholding only - most precise

Community

As more OWLs are built and fallow weed control systems developed, we would love to share the end results. Please get in contact and we can upload images of finished systems.
