基于两点的红外图像非均匀性校正算法应用

Application of a nonuniformity correction algorithm for IRFPAs based on two points

红外焦平面探测器像元响应存在非均匀性,工程应用中需采用相应的非均匀性校正技术。虽然基于场景的非均匀性校正算法很多,但两点校正算法仍是最为成熟和最容易实现的算法之一。介绍了两点非均匀性校正算法,并对1×128线列红外探测成像系统基于FPGA和DSP平台,进行了工程实现及应用,效果良好。

Method of nonuniformity correction (NUC) for infrared imaging system is used in the engineering, as nonuniformity of IRFPA. Although there are many scene-based NUC methods, the two-points correction method is one of easy and matured NUCs. Two-pointscorrection is presented and applied in the engineering, based on FPGA and DSP.
