摘    要:提出了一种新的红外焦平面器件非均匀性自适应多点校正算法,该算法利用自适应滤波技术获取探测器在某一定标辐照度下稳定工作时的权值,并利用该权值去除探测器实时输出图像的温度漂移,最后对去除温度漂移的图像进行三次样条插值多点校正,具有校正精度高、动态范围大和易于工程实时实现等优点.

关 键 词:红外焦平面器件  自适应校正算法  温度漂移  三次样条插值  红外探测器  图像处理

Abstract:A new adaptive multi-point nonuniformity correction algorithm for IRFPA was presented. The algorithm acquires the weights of detector working under a demarcated radiation by using adaptive filtering. The temperature floating of nonuniform IR images was removed by making use of the acquired weights. In the end, the muiti-point nonuniformity correction based on three order spline interpolation to the removed temperature floating IR images is made. The algorithm is with high correction precision, broad dynamic range and easy to realize in engineering.
Keywords:IRFPA  adaptive  temperature floating  three order spline interpolation  multi-point correction
