Abstract:With the development of infrared detector technology, temperature measurement technology based on medium-wave infrared thermal imaging has been more widely used. Based on the study of temperature measurement principle with medium-wave infrared imaging system, the blackbody radiation calibration method and the impact of environmental radiation and calibration data processing method for temperature measurement accuracy are discussed. Then a series of treatment methods to implement a kind of temperature field measurement solution based on medium-wave infrared imaging is put forward, which well compensated the effects of environmental radiation on the measurement results, meanwhile reduced the calibration data fitting errors. The accuracy of temperature measurement is well improved.
