Development of machine-vision technology for inspection of railroad track
Railroad engineering practices and Federal Railroad Administration (FRA) regulations require track to be inspected for physical defects at specified intervals, which may be as often as thrice per week. These inspections are conducted visually by railroad track inspectors, but due to practical …
