Vegetation 3D Localization Process
The methodology for 3D localization of forest vegetation involves several critical steps, from initial image acquisition to the final 3D coordinates calculation and object redefinition.
DLOD Architecture Performance Comparison
A comparative analysis of various YOLO architectures reveals significant differences in training time, inference speed, and accuracy metrics (mAP, Precision, Recall) for forest vegetation detection.
Processing Time Efficiency
Optimized C++ algorithms for 3D coordinate calculation drastically reduce processing time compared to standard OpenCV functions.
Autonomous Forest Cleaning UGV
The developed methodology is directly applicable to Unmanned Ground Vehicles (UGVs) for autonomous forest cleaning, enabling real-time detection, classification, and 3D localization of flammable vegetation. This improves safety, efficiency, and effectiveness in wildfire prevention efforts, especially in complex, steep, and cluttered terrains where manual cleaning is hazardous and labor-intensive. The UGV can precisely target vegetation for removal, significantly reducing fire risk near communities and infrastructure.

Autonomous Forest Cleaning UGV: Real-time 3D localization for UGV wildfire prevention.
The developed methodology is directly applicable to Unmanned Ground Vehicles (UGVs) for autonomous forest cleaning, enabling real-time detection, classification, and 3D localization of flammable vegetation. This improves safety, efficiency, and effectiveness in wildfire prevention efforts, especially in complex, steep, and cluttered terrains where manual cleaning is hazardous and labor-intensive. The UGV can precisely target vegetation for removal, significantly reducing fire risk near communities and infrastructure.
Key impacts:
- Automated identification of fire fuel (e.g., dead vegetation, undergrowth)
- Precise targeting and removal of hazardous vegetation by UGVs
- Enhanced safety for forest workers by replacing manual tasks
- Increased operational efficiency in dense and challenging forest environments
- Reduced wildfire risk near communities and critical infrastructure
