The work deals with the principles of realization of the method of thermographing of the outer surface of chimneys by remote passive thermal vision method with application of a laser-thermographic device. An algorithm for calculation of the geometrical parameters of inner discontinuity is given. It is manifested in the form of surface anomaly of the temperature field. The given algorithm is the base for solving the inverse problem of passive thermography, allowing an improvement of the reliability of assessment of the technical condition of chimneys, and other difficult-of-access industrial facilities.
