Image Based Railway Inspection
In collaboration with Corus, the steelmaker and Loughborough University, Oxford Lasers worked on a DTi funded project to create an image based railway inspection system.
The technology demonstrator that we have built is based on a standard railway push-trolley and incorporates a high-speed imaging system capable of taking high-resolution images of the rail-head at a rate of 5km/hour. The high-resolution images are processed offline with software which has been specially trained to recognise potential track faults.
The collaborative project ran for three years from Mid-2005 until 2008 and, following completion is being marketed by Corus' rail technology division. Our participation in the project allowed us to develop our image capture software and gave us experience in illuminating shiny surfaces.
Over the course of the project, we conducted track trials at various railway sites around the UK and were able to demonstrate the our trolley-based imaging system was able to produce consistent results regardless of background lighting conditions.
