bul 2004 International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B-YF. Istanbul 2004 Result can be gotten from the experiment: double 1. When the measured error is 0, the targets" positioning r which error calculated is computation error. In flat area, horizontal precision is relatively high, but the vertical error targets’ is greater. In mountain area, the targets’ error mainly varying caused by the terrain relief. In this experiment, the horizontal error is smaller than 15 meters in X direction ie. the and in Y direction is smaller than 14 meters. And the ; 10%, altitude error is very great. So this method is good for ; 20%, horizontal positioning but not suitable for the altitude %, and poisoning. % The 2. Result can be found from the second and third group im, and of experiment (overlap is 20% or 30%) that the horizontal eriment error is basically unanimous, and mainly influenced by the terrain relief. The horizontal precision is great. Error both in X and Y direction are not more than 30 meters (in the limit of double maximum square error caused by the measured error which is 0.02 mm). When the overlap measure is as big as 60%, the horizontal precision reaches in cm grade, and the vertical error is about 1 meters. 3. The targets' positioning error is up to the linear increase of measured error. 4. CONCLUSION The following conclusion can be summarized through above experiment and analysis. I. When satellites’ position can be determined by GPS accurately, the targets’ positioning can be implemented. For the characteristic of the area adjacent images overlay can be used to correct the attitude of the images. The method stated in this paper is correct and feasible, and it offers a scientific approach of targets’ positioning with no GCP. 2. In this approach, the precision of the photograph measurement is the main factor influencing the targets’ positioning. So the responding points can be found out with automatic match technology, in order to dispel the influence of the measured error as much as possible. 3. The experiment of this method is still on the basis of the simulated data at present. So the next job is to utilize the true satellite remote sensing data and the aerial triangulation principle deepening the research on this model in order to form the practical method of the image orientation with few or even no GCP. 20% 113
