Improvement of thermographic imaging device by using an automatic scanning system as opaque for infrared radiation of a matrix aperture with a window of transparency at the lens of the thermal imaging lens, leads to improvement of the spatial and temporal characteristics of the thermal imager, namely, its separation from the point of view. As a result of the experiments, it was found that the spatial resolution of the improved thermographic method (compared to the standard method of determination) was improved by 15 – 20%, and the spectral resolution by 0.3 – 0.5 μm. According to the results of the analysis of the processed image, the adjusted temperature scale of the thermogram, which, in turn, allowed to increase the accuracy of temperature determination in each accurate image (the temperature distribution error did not exceed 5.5%).

The peculiarities of carrying out the basic methods of solving the problems of identification, which have become widespread in transport technologies, are considered. Three approaches were tested: a deterministic approach based on the method of selected points, a statistical approach that includes the least-squares method, and – an inductive approach – a method of group accounting of arguments. A number of experiments have been conducted, which is based on structural optimization of the model. In the process of analysis of the obtained models, a rational model of setting and solving identification problems in transport technologies of optimal complexity was obtained. This systematic flow diagram can be successfully applied to solve complex analytical tasks.
