Non-contact electro-optical systems for geometrical parameters measurements of moving objects are the novel systems, which is required for industry and transportation. The electro-optical systems based on lasers, photosensitive cameras, control electronics and computers have been considered. Analysis of principles and existing methods for optical and electro-optical profile measurements was shown. Methods and mathematical models for evaluation of electro-optical measurement accuracy have been developed. Rail track inspection systems in the world and our developments have been considered.
