AN APPROACH TO DETERMINING THE ELEMENTS OF THE EXTERNAL ORIENTATION OF PHOTOS WITHOUT USING GROUND-BASED MEASUREMENTS BASED ON DATA FROM GLOBAL SATELLITE RADIONAVIGATION SYSTEMS
The article is devoted to solving the actual issue of obtaining photo plans and maps without using a planned - altitude basis. It is proposed to improve the method for determining the elements of external orientation by jointly processing a pair of overlapping frame images of the terrain. A special feature of the approach is the possibility of its full automation based on the comparison of central points on overlapping images. As a result, it is possible to obtain photoplanes and orthophotoplanes in a time mode close to real time on board the aircraft. The proposed method for obtaining elements of external orientation of images will improve the accuracy of determining the coordinates of terrain objects during remote sensing without the use of planned altitude training.
