Abstract: This paper is based on "strict geometric model based on affine transformation for remote sensing image with high resolution",amending the strict geometric model of the calculation for the position and orientation parameters of the remote sensing image with high resolution.According to condition of CCD scanning Earth,amend and get a more exact geometric model,whose computation formula is inferred.Experiments demonstrate the new model is more strict and reliable,though it has the same effect as the(original) model.
