【正文】 y shows that geographical information that is useful to us. This article analyses the purpose, significance and method of remote sensing image processing and parison of a number of image preprocessing in the basic principles of. Operation followed by ENVI software, perfect in theory the oute does not meet some real action. Paper mainly introduces the geometry of the image correction, image fusion, image inlay and cropping some of the experiments, in order to more clearly understand the principles of remote sensing image processing operations, paper also outlined some basic models and algorithms. Paper after each processing process is pleted, have corresponding parative analysis of image, clarified the purpose of using ENVI image processing, and analysis in the study of purpose. This paper studies, to continue the study of remote sensing image processing reconciliation later translation of relevant knowledge can greatly help. Key words: Remote sensing。 ENVI。 preprocessing of rs images。 enhancement of images。 geometric rectification。Image Fusion 目 錄 摘要
