Zusammenfassung:	The present invention relates to a system and method for the automated inspection of geometric parameters of railway wheels rolling on a track by artificial vision techniques. The present invention uses a structured light source ( 10 ) that illuminates a line of light (12) upon a fraction of the surface of revolution (3) of a wheel ( 1 ), a CCD camera ( 20 ), which captures an image (21) of the illuminated area, and a data processing system that records, digitalizes, geometrically corrects and reconstructs information of the surface of revolution (3) that is not recorded in the image ( 21 ), in order to obtain a numeric description of the complete transverse section of the wheel (1) represented by a reconstructed profilogram ( 500 ) for calculating the geometric parameters of the wheel ( 1 ).
