Abstract :
In this paper a new method is proposed to solve the problem of high resolution satellite imagery without GCPs by considering the consecutive imaging parameters. That is, the imaging parameters of consecutive imagery are calculated based on GCPs in order to set up the prediction formula, and then the imaging parameters of high resolution imagery can be forecasted. Thus the rigorous model is introduced to precisely locate imagery. QuickBird imagery is test and geo-referencing accuracy reaches 3-4 pixels.
