Abstract

This article takes apart the reason which a serial of the IR images comes into being non-uniformity (speckle) background in the light of the characteristic and using of IR camera. It analyses the merit and defect on traditional non-linear correction methods dealing with a serial of the IR images on the shooting range. It puts forward the new method of non-linear correction of IR images based on the linear calibration in real time serving background changing in course of tracing targets. The new method overcomes traditional abuse and obtains real-time coefficient of gain correction and correction factor. It eliminates non-uniformity background of a serial of the IR images. The experimental results using puny targets of a serial of the IR images on the shooting range shows that the new method not only wipes off the noise of the fixed-pattern and eliminates bad-cell of sensor

but also outputs a serial of the perfect IR images.
