摘要
遥感图像处理向微机化发展是遥感技术引人注目的发展趋势之一．本文采用LANDSAT－5TM数字图象借助适用于微机的软件系统，对TM图象分别进行了主成分交换和彩色空间变换，讨论了这两种变换的意义及其相互结合的优势．这项试验研究在遥感图象微机应用处理、区域资源和环境调查、监测以及研究中有一定的实际意义．
The application of remote sensing technology in 1990s has stepped into the stage of commerdalization and socialization all over the world. One of the spectacular development trends of remote sensing technilogy in 1990s is the microcomputer based image processing.In this study, the popular personal computer and the software IDRISI for processing the multibands of TM imagcs with principal component analysis (PCA) and colour space transformation (IHS) are used. The superiority of the combination of PCA transformation with IHS transformation are discussed. The purpose of this experimental study is to make it play a practical role in the microcomputer based image processing, investigation, inspection and research on regional resources and environment.
