Adaptive non-uniform correcting method for stare infrared focal plane detector

The present invention relates to a staring infrared focal plane detector adaptive non-uniformity correction method. It is characterized by that it uses the parameters of three fields of environmental temperature, prestored several parameter matrixes and image matrix obtained by detector as calculation basis of compensation algorithm, makes the preset correction parameters under the different working conditions and image matrix actually collected by detector undergo the process of algorithm iteration and utilizes the calculated result to adaptively correct current correction parameter matrix of detector.
