Current inspection methods for large critical infrastructures, such as bridges and dams, involve climbers on ropes or scaffolding and are slow, expensive, and dangerous. In partnership with a drone company, we could use drones to fly over concrete structures and capture thousands of images with no risk to people or equipment. Then our proprietary AI models trained on similar infrastructure will process the images to segment the defects such as cracking, crazing, blistering, delamination, efflorescence, spalling, corrosion, and exposed rebar. This pipeline helps IHI identify defective areas in hours without spending a lot of money and months of labor.
