Measurement of body temperature is a vital parameter when monitoring newborns. The peculiarity of thermometry of newborns involves certain anatomical features of children, which make them vulnerable to changes in environmental temperature. These features include: the reduced amount of subcutaneous fat, thin epidermis, blood vessels located near the surface of the skin. This paper demonstrates the choice of the method of converting the original biometric data into the thermal map, as well as the analysis of the obtained experimental thermal imaging data of using the pyrometric method of scanning the incubator bed for newborns.
