摘要：

Image uniformity and accurate radiometric calibration are key features of state-of-the-art infrared cameras. Over the past years several non-uniformity correction and radiometric calibration techniques have been developed. In this paper we present and compare different techniques: 2-point calibration, CNUC (TM)/multi-point's calibration and Telops' Real-Time Image Processing (patent-pending). For each method we assess the performances, the ease of use, the advantages and drawbacks as well as the most important operational limitations considering a broad range of exposure times, ambient and scene temperatures.
