摘要
在进行图像处理时,图像配准是一个必不可缺的步骤,而且图像配准也在很多领域有着广泛的应用,比如图像镶嵌、环境检测、多光谱分类等。对一般的遥感图像配准流程进行简要介绍,然后对遥感图像配准领域出现的最新技术进行总结,从原理和性能上对常用的三类算法进行了对比分析,并指出了各算法在图像配准中的优势及存在的问题。最后总结并指出了图像配准技术存在的主要问题,并展望了其未来的发展方向。
Image Registration（IR） technology is the indispenable key step of image processing technologies,it is widely used in image mosaicing,environmental monitoring and multi-spectrum image classification etc.In this paper,first the flow of remote sensing image registration introduced briefly,then summarizes the new registration technologies for remote sensing images.This paper also compares three kinds of common algorithm from aspects of principles and registration performance and put forward the advantages and disadvantages of each methods.At last it summarizes and points out the difficulties of remote sensing image registration techniques,and presents the prospects.
