Influence of equipment, weather and personnel experience on the digitalization and damage detection of concrete bridges
Abstract Traditional visual inspections of existing infrastructure have limitations such as safety risks, limited accuracy for subsurface defects, and subjective assessments. Modern inspection techniques like terrestrial laser scanning, closerange photogrammetry (CRP), and infrared scanning offer fa...
