Paper Abstract

At present there are exist comprehensive studies in the field of railway track condition monitoring systems and development of non-contact photonic systems (NCPS) based on digital CCD-cameras, high-speed board computers and powerful software. It consists of four special digital matrix CCD- cameras and four laser stripe illuminators. They are rigidly connected and structurally fixed on a wheel set of the track inspection vehicle in such manner that the corners of observation and the distances from the cameras up to the head of the rail during movement of the vehicle remain fixed. Distortions obtained when using Euler planes' formulas can be removed by applying coordinates conformity system. According to the algorithms made a cut-off method and tangent methods have been compared.
