Paper Abstract

An accuracy assessment method of infrared camera laboratory radiometric calibration was studied for the sake of validation of space infrared camera measured data. Firstly, image process of infrared camera was analyzed and modeled on laboratory radiometric calibration, a model of linear radiometric calibration coefficient synthesized impact chain was built; secondly, based on the model, a model of uncertainty of linear radiometric calibration coefficient was built; finally, An experiment verified the validity of the model. The results of experiment indicate that the difference between the assessment value and maximum experiment value is 0.08% and the difference between the assessment value and average of experiment values is 0.79% at gain uncertainty assessment, the difference between the assessment value and maximum experiment value is 0.7%, the difference between the assessment value and average of experiment values is 0.18% at offset uncertainty assessment, the uncertainty of coefficients of radiometric calibration get from experiments is basically consistent with the assessment. The method of accuracy assessment of radiometric calibration combined with chain factors uncertainty can avoid omitting and repetition in uncertainty estimation; optimization of camera used for quantification can be designed on the method.
