一种SAR影像辅助的光学卫星影像自动几何定位方法
Automatic Geometric Positioning Method for Optical Satellite Images Assisted by SAR Images
摘要
Abstract
We proposed a high-precision automatic geometric positioning method for optical satellite images assisted by SAR images,which took advantage of the complementary characteristics of SAR and optical satellite images in geometric positioning.Firstly,the SAR DOMs and the target optical satellite images were superimposed detection.Then,a multi-modal matching algorithm was used to perform image matching and control point optimization for optical images and SAR DOMs.Finally,the matched virtual control points and optical images were used as input information,and perform block adjustment using the rational function model to achieve accurate geometric positioning of optical satellite images.The method proposed in this paper can greatly improve the geometric positioning accuracy of optical satellite images,and hashigh automatic calculation efficiency,which has certain guiding significance for the rapid update production of topographic maps in the field of photogrammetry.关键词
