Research on Key Technologies of Uncooled Infrared Thermal Imaging Temperature Measurement
The temperature measurement process based on uncooled infrared thermal imaging is challenging to achieve high accuracy in complex environments due to various factors such as ambient temperature,temperature measurement distance,and atmospheric humidity.To achieve accurate temperature measurement requirements in complex environments,the main influencing factors and key correction technologies for uncooled infrared ther-mal imaging temperature measurement errors have been analyzed and studied.Firstly,an algorithm for predict-ing the radiation temperature of uncooled infrared detectors is designed based on particle swarm optimization for backpropagation neural networks,addressing the influence of environmental factors on the radiation temperature of uncooled infrared detectors.This algorithm achieved accurate estimation of radiation temperature under differ-ent working environment temperatures.Secondly,a method based on atmospheric transmission software is de-signed to accurately,quickly,and conveniently calculate the atmospheric transmittance of near-ground infrared radiation,facilitating the correction of atmospheric environmental interference during the temperature measure-ment process.Finally,a comprehensive uncooled infrared thermal imaging temperature measurement method is designed by integrating the proposed essential correction techniques,which experimentally verified the effective-ness of the proposed method in improving infrared temperature measurement accuracy and environmental adapt-ability.
