Drones Can Now Spot Hidden Rust Without Stripping Paint
What Happened
Researchers developed a drone-compatible corrosion detection method that can identify rust beneath paint using just three optical spectral bands and texture analysis, without the need for heating equipment. The system achieved over 90% accuracy in detecting both surface and subsurface corrosion across different coatings.
Key Takeaways
The technology could make inspections of ships, bridges and industrial infrastructure faster, safer and cheaper, enabling drones to detect hidden corrosion before it causes costly failures.
