| Abstract: | Based on the theory of infrared radiation and the principles of temperature measurement of infrared thermography, the calculating formulas of the influencing factors of the relative temperature difference was deduced. The influence of the environment temperature, the emissivity of target surface and the working wave band of thermography on the relative temperature difference was analysized. It is shown that the environment temperature has a little effects on the relative temperature difference,the emissivity has an effect on it to a degree,and the long wave band thermography has less effects on the relative temperature difference than the short wave band. |
