| 摘 要： | 本文简要地介绍了遥感图象的典型变换方法的数学原理,提出了建立典型变换矩阵的两种方法:(1)从野外地物反射波谱数据的典型分析求出;(2)直接从遥感数字图象的亮度值数据求出。文中还讨论了地面反射波谱的典型分析结果与多光谱遥感图象亮度值典型分析结果之间的关系,论述了将地面波谱典型分析结果用于数字遥感图象处理的可行性。简述了在101图象处理系统上实现典型变换的步骤。最后给出两个用于岩性识别的实例。

| Abstract: | Two methodes to obtain the canonical transformation matrix are presented in this paper. One is to calculate the matrix from the canonical analysis of the field spectral data of objects; The other derives it directly from the DN values of the targets in digital image. The relationship between the results of canonical analysis of field reflectance data and that of DN values of same objects is discussed also in this paper. At last, two examples using those methods for lithologic discrimination in remote sensing images are given. |
