Visual Inspection of Railroad TracksPhase II
Mobile Platform Design
Basler A400 High speed firewire
Mobile Platform
The main factors driving the design of the mobile platform are: Portability Image Stability Uniformity of
Illumination conditions
Mobile platform
Video obtained from mobile platform
Example rail video obtained from mobile platform
Defect detection
Engine Burn Defects
A condition in which the rail has been scarred by the heat created by locomotive.
Appearance in track. Round or oval rough spots or holes on the surface of the rail.
