| 摘 要： | 针对全向激光告警系统中SWIRFPA的盲元补偿问题,提出一种基于邻域灰度特性的加权插值盲元补偿算法.阐述该算法的基本思想和原理,根据盲元邻域灰度值的分布情况,赋予每个邻域像元与其灰度值相关的权重,进而完成盲元补偿.从主客观2个角度对补偿效果进行评价.结果表明:与传统的邻域平均法和中值滤波法相比,加权插值盲元补偿算法对全向激光告警系统中SWIRFPA的盲元补偿效果最好,不仅使盲元补偿值与其邻域偏差最小,而且减小了盲元对系统探测的影响,有效提高了系统性能.

| Abstract: | In order to implement blind-pixel compensation for IRFPA in omni-directional laser warning system,a new weighted interpolation algorithm based on neighborhood grey character is presented.The impact of blind-pixel on the system was analyzed,the basic concept and principle of the algorithm were elaborated and analyzed,and the algorithm was verified by experimental simulation.Finally,the blind-pixel compensation result was evaluated subjectively and objectively.Compared with the conventional algorithms of neig... |
