摘　　要：为了提高红外焦平面阵列多点实时非均匀性校正的速度,提出多点压缩校正的新方法。介绍了多点压缩校正方法的原理,在此基础上详细阐述了多点压缩的硬件实现过程,并通过与传统多点校正方法的比较,说明了多点压缩校正方法的有效性。实验结果表明多点压缩校正具有计算量小、实时校正速度高、校正后图像的残余非均匀性小等优点。In order to increase multi-point real-time nonuniformity correction speed of infrared focal plane arrays （IRFPA）, a new method of multi-point compression correction is proposed. The theory and the implementation process of multi-point compression correction are expounded, by comparing multi-point correction with many points compression correction. The comparative results show the advantages of less calculation, higher real-time correction speed and less remnant nonuniformity from multi-point compression correction, and this helps to real-time nonuniformity correction of IRFPA.
