Abstract本文讨论了随机滤光片光谱编码-解码的基本原理与重构方法,利用深度学习欠完备自编码器的自动特征提取机制,构建了高精度、低延时的像元映射变分辨率光谱成像重构网络,通过变换像元映射关系完成了2×2、4×4像元阵列光谱重构网络的并行训练。最后,利用512×512、120谱段(430~670 nm)的遥感光谱图像对重构网络进行验证,实现了2×2像元阵列/40谱段重构峰值信噪比达53 dB、均方误差小于0.002、重构用时0.87 s与4×4像元阵列/120谱段重构峰值信噪比达64 dB、均方误差小于10-5、重构用时0.52 s的变分辨率光谱图像重构。实验结果表明像元映射变分辨率光谱成像重构网络具备高精度、低延时的动态变换性能。
