Rail Corrugation Detection and Characterization Using Computer Vision [PDF]

open access: yesSensors, 2021
Rail corrugation appears as oscillatory wear on the rail surface caused by the interaction between the train wheels and the railway. Corrugation shortens railway service life and forces early rail replacement.
