The infrared thermal imaging systems are widely used for distinguishing target radiation temperature difference and they can also be used to measure the absolute temperature of the target. The infrared thermal imaging systems with temperature calibration made in laboratory cannot be applied for field temperature measurement because that they cannot simulate and compensate the complicated atmosphere absorption. We must correct the atmosphere transmission coefficient in order to obtain the accurate temperature measurement of the target. In this paper, we present a method for correction of the atmosphere transmission coefficient. Firstly, we use a standard expanded area blackbody to determine the second atmosphere transmission coefficient of the infrared thermal imaging system. Next, we correct the infrared thermal imaging by using a target with known emissivity. Finally, we can use the infrared thermal imaging system to measure the radiation temperature of the unknown radiation object.
