Applicability Analysis of Generalized Sensor Models for Quickbird Imagery

Abstract:

An investigation is carried out on the applicability of several main generalized sensor models for QuickBird high resolution satellite imagery.The timevariant parallel perspective model was proposed and proved to be the most suitable model to describe the imaging geometry of the QuickBird imagery. Stereo positioning experiments and accuracy analysis were then made by using the QuickBird stereo image pair in Shanghai district based on the proposed model. The results show that stereo positioning accuracy of the timevariant parallel perspective model is very close to that of the biascompensated rational function model,and the planimetric positioning accuracy reaches subpixel level.
