遥感变化检测技术发展综述

REVIEW OF THE DEVELOPMENT OF REMOTE SENSING CHANGE DETECTION TECHNOLOGY

卫星遥感的复轨能力 ,稳定一致的传感器参数和系列运行计划 ,连续记录了地表的显著变化信息。对遥感观测到的变化信息 ,还需要区分是地表物理生物要素变化引起的变化 ,还是辐射传输路径上其它干扰因素造成的变化信息 ,需要从各种变化信息组分中区分目标变化信息。因此 ,遥感变化检测是遥感信息科学、地球系统科学、统计学和计算机技术等学科技术交叉后新的增长点 ,代表了当前遥感数据处理技术发展方向。为了促进遥感变化检测技术在我国的发展 ,收集阅读了近几年国外主要遥感刊物发表的论文、专著 。

The satellites track review, stable and constant sensor parameters, as well as systematic operation plan enable us to continuously observe and depict the Earth surface and to record distinct changes. For the changed information observed, it is necessary to determine whether the change results from the natural processing of bio geophysical factors or the change results from satellite system or from our targets of interest. Therefore, remote sensing change detection technology is much more complex than remote sensing data processing algorithms usually used in our operation system. It is a newly developed remote sensing temporal data processing system by combining selected radiometric correction, image matching, geometric correction and post classification analysis and vector analysis to finish one assignment. It is change target objective oriented procedure by combining remote sensing information science, earth sciences, statistics and computer sciences. In order to promote the remote sensing change detection in Chinese remote sensing community, we wrote this paper based on what we learned from nearly 200 books, articles, papers, project reports and Internet information.
