摘要: 首先分析了利用影像进行变化检测的紧迫要求和存在的困难,接着对变化检测的方法进行分类,提出将影像配准与变化检测整体同步解求的思想和在此基础上进行三维变化检测的可能性,并在文中概要介绍和比较了各种变化检测的7种方法,最后展望了下一步应继续研究的方向。

Abstract: Firstly the problems and difficulty of current change detection techniques are presented in this paper.Then according to whether registration is done before change detection algorithms,the author classifies change detections into two categories:change detection after image registration and change detection simultaneous with image registration.For the former,four topics are introduced and described.For the latter,three categories are discussed.Last the future prospect for change detection techniques is given.
- change detection /
- geographical spatial information /
- image registration /
- feature matching
