【 摘 要 】

Along with the development of unmanned aerial vehicles (UAVs), popularization of digital cameras and other progress in photogrammetric technologies, images obtained from different heights of flight are of great interest to scientists. One of the main advantages of UAVs when changing altitude is that they can receive images with a very high resolution of the earth. High resolution images have great potential in many situations, such as large-scale mapping, archeology, 3D modeling of cities, quarries in mining. Limiting the continuity of the terrain, which is used by most traditional matching algorithms, is unacceptable, and most traditional photogrammetric programs cannot cope with the images obtained by the UAV at different altitudes. In this paper, we propose a new approach to change the altitude of the UAV depending on the terrain, as well as determine the dependence of the accuracy of shooting from the altitude.
