Diagnostics of External Defects of Railway Infrastructure by Analysis of its Images

An important component of the safe movement of the railway transport is the absence of visible rail defects. The external defects of the track infrastructure were analyzed according to the criteria of detection accuracy and the conditions of applicability of the methods of their detection. For the diagnostics of the railway track, a passive defectoscopy method, based on stereo vision and blur analysis, is proposed. This system can be implemented in a hardware-software control system and is located on ground transport-technological devices.
