【摘要】 遥感图像配准是遥感图像拼接、信息融合的基础,是对遥感图像定量应用和研究的关键环节。MATLAB的图像处理工具箱IPT(Image Processing Toolbox)提供有基于点特征进行图像配准的函数,利用这些函数可以方便快捷地完成图像之间的配准。论文首先对图像配准及基于点特征的遥感图像配准作了详细的介绍,然后对IPT中配准函数的语法格式作了详尽的分析,并对两幅遥感图像进行了配准操作,最后对该方法进行了结论性分析,阐明该方法的应用价值与可改进之处。更多还原

【Abstract】 Remote sensing image registration is the base of remote sensing image mosaicing and information fusion,and the key part for quantitive research and application of remote sensing image.The IPT(Image Processing Toolbox)of MATLAB provides the functions for image registration based on the character of points.It is simple to implement the registration between images using the functions.This paper firstly introduced the image registration and remote sensing image registration based on the character of points in detail.Then it analyzed the syntax and format of the registration function in LPT and implemented the registration between 2 remote sensing images.Finally,it analyzed the method and put forward the application value and the improving points of the method.更多还原
