Researchers develop two-level AI framework for more informative steel bridge corrosion inspection

Executive Briefing & Key Highlights

Corrosion is a major concern for aging steel bridges because progressive material loss can affect their long-term serviceability and, in severe cases, structural safety. Visual inspection remains indispensable for assessing bridge condition, but inspectors must evaluate corrosion under widely varying conditions, including differences in lighting, coating color, shadows, surface deposits, structura
