基于单应性矩阵的SAR图像配准技术研究

Research on SAR Image Registration Based on Homograph Matrix

通过分析单应性矩阵的特点,提出利用单应性矩阵来表示待配准SAR图像与参考矢量图像之间的空间变换模型,并以地理信息系统矢量图为参考,针对某局部遥感图像,分析了SAR图像的配准过程及配准结果。配准结果表明文章提出的配准方法具有人机交互少、算法鲁棒、配准效果好的优点。

Homograph matrix is introduced and presented as the image space transform model between SAR image and vector image. Using the GIS （ Geographic Information System） vector image as the referring image, the process and results of SAR image registration is analyzed. The registration results indicate that based on the homograph matrix, the SAR image registration method has some merits of less manipulation, robust algorithm and effective registration result.
