| 摘 要： | 本文探讨ＨＩＳ变换对数字化航空片影象与ｌａｎｄｓａｔ ＴＭ多光谱影象进行复合的方法，并在此基础上提出一种改进的方法。试验结果表明本文提出的方法是一种非常行之有效的方法。复合后的影象不仅保留了ＴＭ影像的光谱特征，而且将其空间分解力由３０ｍ提高到１０ｍ，清晰度也提高了。因而复合后的影像能提高分类精度，制作专题图的精度、多时相监测能力和解译水平等。

| Abstract: | This paper discusses the merging of digital aero-photo images with Landsat TM multispectral images by using HIS transformation, and presents on this basis an improvement method. Results showed that this new method is very efficient: the merged images can not only preserve the original spectral characteristics, moreover can raise the spatial resolution from 30m to 10m, thus improving the mapping precision, the multi-time-phase survey capability and the explanation level. |
