基于RPC模型的QuickBird影像正射纠正

The Research on QuickBird Images Ortho-rectificationBased On RPM

高分辨率卫星出于技术保密的考虑一般不提供严格的传感器物理模型,而通用传感器模型由于与具体的传感器无关,因而更能适应传感器成像方式多样化的发展要求,成为人们研究的一个热点问题。本文采用基于有理函数模型的方法来生成QuickBird的正射影像,分析了生成影像的定位精度,指出了采用该模型还需进一步要研究的问题。

The high-resolution satellites usually do not supply the strict physical sensors models for technology confidencial consideration.However,because the general sensors models have no relation on the specific sensors,so it can be more adaptable to the sensors imaging models＇ diversifaction requirements,thus,it becomes to be a hit point for people research.This paper use RPC model to generate QuickBird ortho-Images,then,it analyses the prseaecision of ortho-images＇ positioning,then it gives some questions which need to be further rerched.
