1. A system to monitor railway wheels having sides arranged in parallel, the sides including an inner side and an outer side and a surface disposed perpendicularly in a space defined between the inner side and the outer side of the railway wheel, comprising:

  • a system to measure a profile of the railway wheel comprising stereo cameras, including a first stereo camera and a second stereo camera;

    a system to analyze the profile of the railway wheel based on a theoretical two-dimensional model of the railway wheel in a perfect condition; and

    a system to analyze the surface of the railway wheel based on a theoretical three-dimensional model of the railway wheel in the perfect condition,wherein the stereo cameras are configured to capture images of the sides of the railway wheel, the first stereo camera capturing first images of the inner side of the railway wheel and the second stereo camera capturing second images of the outer side, andwherein the images captured by the stereo cameras are subjected to computational processing configured to generate a first three-dimensional reconstruction of the first side and a second three-dimensional reconstruction of the second side of the railway wheel.
