Railroad tracks need to be periodically inspected and monitored to ensure safe transportation. Automated track inspection using computer vision and pattern recognition methods has recently shown the potential to improve safety by allowing for more frequent inspections while reducing human errors. Achieving full automation is still very challenging due to the number of different possible failure modes,...
Periodic inspections are necessary to keep railroad tracks in state of good repair and prevent train accidents. Automatic track inspection using machine vision technology has become a very effective inspection tool. Because of its non-contact nature, this technology can be deployed on virtually any railway vehicle to continuously survey the tracks and send exception reports to track maintenance personnel...
Fasteners are critical railway components that maintain the rails in a fixed position. Their failure can lead to train derailments due to gage widening or wheel climb, so their condition needs to be periodically monitored. Several computer vision methods have been proposed in the literature for track inspection applications. However, these methods are not robust to clutter and background noise present...
