基于场景的红外探测器非均匀性校正方法可以弥补基于黑体辐射定标的非均匀性校正方法存在的缺陷, 目前许多公开发表的场景校正算法比较复杂, 难于硬件和工程化实现。探索了一种基于帧间图像配准的场景校正算法, 针对国产 640×512中波制冷型红外探测器存在的非均匀性应用该算法进行了校正实验。实验结果表明该算法校正效果明显, 为基于场景的非均匀性校正算法的工程化应用提供了一种新思路。

Scene-based NUC algorithms can make up the deficiencies of reference-based NUC. At present, many scene-based NUC algorithms published are complicated, so it’s difficult to apply them into hardware and projects. The paper uses a scene-based NUC algorithm by means of image registration, and applies it to the nonuniformity correction of domestic-made 640×512 MW cooled IR detector. The experiment result indicates that this algorithm is effective, which provides a new thought for the engineering application of scene-based NUC algorithms.
