Inspection of the railway tracks

Operators of railway systems must regularly inspect railway tracks as part of maintaining their systems to ensure operational safety and traffic capacity. The maintenance work includes inspection of rails, ties, ballast bed and mounting system. Multiple high-end or Ranger 3D cameras are mounted on an inspection vehicle. These cameras provide accurate cross-section profiles from which the complete geometry of the track is calculated. Up to 30,000 profiles per second provide quick inspection to allow regular railway traffic to run at full operational speed and to keep maintenance costs down. The Ruler high-end camera is pre-calibrated and outputs 3D coordinates. With the Ranger high-end camera, the working distance and field of view can be easily adjusted.
