Concept of binocular stereo vision system for inspection of surfaces

The article presents the idea of a binocular stereo vision system for surface inspection and discusses the basic characteristics of epipolar geometry and the advantages and limitations of the methods of representation that use it. The structure of the vision system, basic optical parameters and the configuration of the equipment are presented. The assumed practical implementation possibilities are determined. 1. Review of methods of monitoring the materials destruction processes One of the basic issues in materials and structure testing is the fatigue strength and cracking susceptibility when influenced by loads of different character and intensity. The problem of fatigue strength has a multi-scale character. Most of all, it concerns the operation and maintenance of technical objects and, with reference to supporting structures, machines and devices, is hence analysed on a macro scale. Together with the development of the advanced material technologies and mechatronic technologies, the problem of testing the fatigue strength on a micro scale is growing in importance. The multi-scale of the material destruction processes, most importantly fatigue cracking, generally results
