Abstract
It is described a system and method to monitor railway wheels, which includes obtaining images of the railway wheel by means of stereo cameras and performing a three-dimensional and two-dimensional model of the railway wheel by means of these images. This two-dimensional model is subjected to analysis of the profile of the railway wheel, comparing it with a two-dimensional model of an ideal wheel and thus measuring the effective wear of its profile. The three-dimensional model is subjected to analysis of the surface of the railway wheel, also comparing it with a three-dimensional model of an ideal wheel and thus measuring the effective wear of its surface.
