Non-uniformity correction of IRFPA is an important link in improving the quality of infrared imaging system. Non-uniformity correction algorithm is mainly divided into calibration class correction algorithm based on reference radiation source and the correction al-gorithm based on scene. Calibration class correction algorithm based on reference radiation source is subdivided according to the linear models and nonlinear models,and correction algorithm based on scene is subdivided according to the spatial and temporal domain. Ac-cording to the characteristics of different algorithms,each of the algorithms above are analyzed and compared in detail. Provide the theo-retical foundation for choice of non-uniformity correction algorithm,and according to the characteristics of two kinds of algorithms,pro-pose the algorithm research direction in the future.
