The typical accuracy of infrared cameras specified by their manufacturers amounts to ±2 K or ±2 % of the measured value of temperature. Very often a better accuracy of the measurements is required, e.g. during the measurements of human body temperature. To improve the measurement accuracy an external correction of obtained results on the basis of comparison measurement of black body temperature and next with use of MATLAB package has been proposed.
