Abstract
In order to improve the efficiency of infrared radiometric calibration, a simplified calibration method is put forward. Firstly, a radiometric calibration model comprising integral time is proposed, and the correctness is verified by curves of gray value versus integral time and gray value versus radiance. Then a simplified method for radiometric calibration is deduced. Therefore calibration at all integral times can be obtained by using only three infrared images collected at two typical integral times. Finally, the experiments are designed to illustrate the accuracy of calibration and radiation measurement based on the proposed simplified method. Experimental results illustrate the effectiveness of the proposed simplified calibration method,it improves the efficiency of radiometric calibration greatly, and can be directly applied to target radiation measurement tasks.
