Abstract
The infrared thermal imager is widely used in infrared radiation measurement, but the accuracy of radiation measurement is greatly affected by the changing environment and self-heating effect. In this article, the influence of self-heating effect is analyzed in a stable environment and the phenomenon of temperature drift caused by the self-heating effect is found. Then the drift rules are summarized by experiment, and a weighted-based compensation method is presented, the result shows that the temperature measurement error is less than 0.7 centigrade after compensation.
