Revolutionizing firefighter safety through advanced AI and computer vision technologies that see through smoke, darkness, and challenging fireground conditions
This research explores how to make Artificial Intelligence (AI) more reliable for use in firefighting scenes. A key challenge is that photos and videos from a fire are often dark, smoky, and unclear, which makes it difficult for AI to accurately identify firefighters and fire trucks.
The study tested two advanced image enhancement techniques—CLAHE (contrast enhancement) and Zero-DCE (brightness enhancement)—to improve AI object detection. By strategically using these techniques to create more varied training data, the AI's ability to detect objects correctly significantly improved, with firefighter detection precision reaching 82.7% and fire truck detection achieving 94.5% accuracy.
Understanding the limitations of current AI systems in emergency response environments
The unpredictable conditions at a fire scene create severe challenges for computer vision systems:
Manual tracking methods create operational inefficiencies and safety risks:
Standard AI models fail in challenging fireground conditions:
Transforming challenging fireground imagery into clear, actionable data for AI systems
Contrast Limited Adaptive Histogram Equalization - This technique makes the differences between light and dark areas more distinct, helping objects stand out from smoky or hazy backgrounds.
Zero-Reference Deep Curve Estimation - This technique intelligently brightens dark images without washing out important details, making objects visible in low-light conditions.
You Only Look Once version 5 - The real-time object detection system used for identifying firefighters and equipment with exceptional speed and accuracy.
Systematic approach to enhancing AI performance through strategic data augmentation
Gather original fireground imagery under various conditions
Apply CLAHE and Zero-DCE techniques to create enhanced versions
Combine original and enhanced images for training dataset
Train YOLOv5 model on enhanced dataset
Test model accuracy on real fireground scenarios
The core innovation of this research lies in using enhanced images for data augmentation rather than direct analysis. By expanding the training dataset with enhanced versions of original photos, the AI learns to recognize objects under a wider variety of conditions, making it more adaptable and robust to the unpredictable nature of fireground environments.
Key Insight: Training the AI only on enhanced images was not effective. The best results came from training on a mixed dataset of both original and contrast-enhanced photos, teaching the system to perform well across all conditions.
