Abstract
A numerical-instrumental approach of thermographic control was developed to improve the efficiency of contactless control of the state of difficult-of-access parts of large-sized structures and constructions. It consists in integrated application of industrial thermal imaging instruments and computational methods of analysis of temperature fields in the studied structures. This allows improving the accuracy of determination of the geometrical features of the defects and reducing the labour consumption of operations of technical diagnostics of the state. Application of the developed approach was demonstrated on typical examples of contactless control of the technical state of industrial chimneys. 10 Ref., 2 Tabl., 6 Fig.
