Due to its unique advantages, infrared temperature measurement technology has been used more and more widely inmedical auxiliary diagnosis, and the change of ambient temperature is an important factor affecting medical infraredtemperature measurement components. This paper builds a simulation platform for ambient temperature. At a fixeddistance, by changing the ambient temperature and the target temperature, a large amount of infrared temperaturemeasurement data is collected, and a two-dimensional compensation model of the scene temperature variation isobtained by combining the infrared focal plane non-uniformity correction and the least squares fitting. The actual sceneexperiment proves that the temperature measurement accuracy and stability have achieved satisfactory results.
