Methods and means of visual and dimensional tests of hard-to-reach nodes of rocket and space equipment

Abstract

The most machine vision-oriented industries are metallurgical, food, household chemicals, automotive and mechanical engineering, as well as pharmaceutical production. These are the areas in which there are increased requirements for the quality of products. An important role in increasing the demand for machine vision technologies was also played by the introduction of a national labeling and product tracking system. However, in the space industry, issues related to machine vision have not been fully resolved by non-destructive testing methods. For the first time in Russia, a prototype measuring stereoscopic video endoscope was developed, manufactured and tested. The authors have developed the software that allows obtaining textured three-dimensional models of objects, measure their geometric parameters, estimate the measurement error, calibrate and configure the system. The technical characteristics of the video endoscope have been confirmed at the level of analogues produced by the world's leading manufacturers. A method of designing probe stereoscopic systems has been developed and applied in practice.
