发布时间:2019-01-30 07:55
【摘要】:对于SAR主影像(master)和从影像(slave)的几何配准,文中采用三次基本多项式与斜距-多普勒定位模型,解算出主影像中心像素点在从影像中的同名点,最后得出主从影像中心像素点的初级配准偏移量。本文以上海地区ERS-1影像数据为例,在Matlab环境下,对SAR主从影像的几何配准偏移量进行解算。实验结果表明,采用文中初级配准方法,初级配准相对精度可达到0.1%~0.9%。
[Abstract]:For the geometric registration of SAR main image (master) and slave image (slave), the cubic fundamental polynomial and oblique range-Doppler localization model are used to solve the homonym point of the central pixel of the main image in the slave image. Finally, the primary registration offset of the central pixel of the master-slave image is obtained. Taking the ERS-1 image data of Shanghai area as an example, the geometric registration offset of SAR master-slave image is calculated under the Matlab environment. The experimental results show that the relative accuracy of primary registration can reach 0.1% by using the primary registration method in this paper.
