摘要：The successful lunch of IKONOS and QUICKBIRD, and a serious of plans for acquiring the remote sensing images with high resolution let it become possible that the basic spatial information is obtained from the remote sensing images in low costing and sort period. The first processing step is calculating the parameters of image position and orientation. Because of the very strong relativity of the traditional parameters of remote image with high resolution, the parameter calculation is not solved perfectly up to now. A strict geometric model, proposed in this paper, adopts a new method with three steps of transformations based on parallel ray projection. The first step is reducing the three dimensional space to the image space by the similar transformation. Then, the small space is projected to the level plane, which passes the center of the image plane, by parallel rays (Affine transformation). Finally, the level image is transformed to the original declining image. Every step of the model is strict, and the map function of each transformation is the first order polynomials and other simple function. The final calculation of the parameters is for the linear equations with good status. As a result, the problem of the relativity of image parameter calculation is solved completely. Some experiments are carried on for a lot of images with 10, 3 and 1-meters resolution. All of the results are quite perfect. Thus, the validity of the strict geometric model has been verified
