Abstract:
This article discusses the shortcomings of existing techniques to obtain spatial and temporal distribution of radiation temperature (cuboid infrared images), is the use of active thermal pulse heating the surface under investigation from the source of infrared radiation to a temperature corresponding to the upper limit of thermal sensitivity of the receiver and the registration thermal imaging receiver radiation temperature in the process active heating and cooling within its spatial resolution. In most of these researchers used a simplified solution of the direct heat conduction problems using empirical relationships The proposed processing method of dynamic infrared images of objects based on general physical and systemic principles: the corresponding mathematical models of physical objects with the use of standards, the calculus of variations, and the residual iterations, in addition, the principle of detection by thermal parameters and presented in the form of a reduction algorithm cuboid IR images. The algorithm reduction cuboid IR images allows for comprehensive numerical study thermophysical processes, to expose them to a numerical experiment by analyzing a variety of situations, and receive information about the buried objects.
