Abstract
This paper first discusses the background and details of Rational Function Model (RFM) which describes the coordinates in image space and object space, and then by incorporating additional parameters into the basic RFM, the bias-compensated RFM is introduced. With different additional parameters, four kinds of bias-compensated RFM are put forward and discussed. Finally an experimental test in Shanghai, China, is carried out with the Bias-compensated Rational Function Model using QuickBird across-track stereo imagery and highly accuracy Ground Control Points (GCP) as data source. Conclusion is drawn that with more well distributed GCPs, high 3D geo-positioning accuracy can be obtained up to about 0.6 meter in plane direction and 0.7 meter in height direction.
