同时对国土卫星像片的几何配准，运用多项式与有限元法相结合的原理，进行了计算机和光学处理的对比研究。

Moreorer a comparative study of computer image processing and optic processing was done to solve the geometric registration of the image using multinomial and finite element method.

由于成像方式不同，SAR图像与光学图像具有很大差异，光学图像的配准方法直接应用于SAR图像配准中往往不能取得令人满意的效果。

But because of different imaging types, SAR image has large difference with optical image, techniques adapt to optical image registration can not be directly used to SAR image registration.
