摘要：The motivation for the test originated from an ISPRS-WGII/7- initiative to establish a general purpose image-transfer standard for photogrammetric applications and remote sensing. While rigorous photogrammetric models guarantee a defined accuracy the rational functions approach allows only a more general statement about the expected accuracy of the points taken from the scene. In order to select one if the either method as appropriate for a given application the effective point accuracy has been tested in a joint project between the ICC (Institut Cartogràfic de Catalunya) in Barcelona and Fachhochschule Neubrandenburg. MOMS-scenes of mountainous and of flat terrain have been used in the test, which has been conducted using various software packages from ZI-Imaging. Given the orientation of images using a rigorous photogrammetric model there are two parameters to choose the rational functions that approximate the rigorous functions. The first one is the degree of the rational function. The second is the set of points, which coordinates are known through the rigorous model, used in the computation of the rational functions coefficients. In this paper a comparison between rational functions (changing the parameters that determine them) and the rigorous model has been done. In addition the dependency on terrain and sensor calibration parameters of the rational functions is discussed
