Researches On Unmanned Airship Mapping Project & Exact Matching In Aerial Triangulation

Unmanned airship remote sensing system is an advanced, efficient and high precision system which is newly developed. It has many advantages that other systems lack of. But, since it's new, it's not widely known.The rapid development of unmanned aircraft photogrammetry, has brought new challenges, that is, how to process the images of difficult terrains which are rarely fond in traditional photogrammetry. As unmanned aircraft have features like low height, small images and complicated aerial stances, current auto aerial triangulation software still has problems making exact matches.This article mainly introduces unmanned airship remote sensing system through Rushan mapping project, and takes MAP-AT as an example, shows and explains the methods and ideas to aim AAT software to process difficult terrains as mountain, forest and water area, and the theories of these methods.
