摘要
在卫星图像配准中地标点的配准是最初且最重要的一步。海岸线等地标点在高分辨率远地卫星图像中表现为边缘,受云层、噪声等边缘干扰,常导致匹配困难。本文提出基于几何信息的轮廓配准方法,使用地球同步卫星图像中海岸线的轮廓信息与通过GSHHS得到的标准图像进行配准得到精确的配准结果。
For geo‐stationary meteorological satellite application ,landmarks registration is the first and most important step .The landmark registration results in high resolution satellite image show as edges which are easy easily to influenced by clouds ,noise and other edge interference ,.In this paper we propose a method based on geometric information ,using shoreline in high resolution satellite image and standard image of landmarks based on GSHHS to get accurate matching points through geometric similarity registration .
