摘要
遥感变化检测技术是遥感信息科学的重要研究领域,是当前遥感数据处理技术的主要发展方向。本文从三个方面介绍遥感变化检测的技术与方法:首先简要介绍遥感变化检测的数据预处理;其次,重点介绍了各种遥感变化检测方法,并对各种方法优缺点做了简单评述;并提出了遥感变化检测中应注意的问题和本研究的几项经验性的结论。
The technology of digital information extraction and change detection is an important research field in remote sensing information science. For the changed information observed , it is necessary to determine whether the change results from the natural pro- ceasing of bio-geophysical factors or the change result s from satellite system as well as from our targets of interest . Three perspectives of change detection in remote sensing were summarized in this paper. First, the pre-processing routines to process remote sensing change detection were established. Second, the actual change detection methods were categorized in an analytical framework and also were evaluated. Ultimately the new developments in change detection were summarized.
