| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 103 === Benefited from the newly developed UAS photogrammetry technology, commercial softwares converting images into photogrammetry productions such as orthophotos, DEM/DSM, contour lines, dense matching models are available. The quality of photogrammetric productions is directly related to the results of the aerotriangulation adjustment of UAS photogrammetry. Regulations about arrangement of ground control points (GCPs) in traditional photogrammetry are announced by National Land Surveying and Mapping Center, Ministry of the Interior (NLSC) for years. With regard to UAS, none of related regulations allows users to follow. In this paper, influence of different arrangement in GCPs with different commercial softwares are presented. All the execution models of the softwares are based on bundle adjustment with self-calibration or/and computer vision. The experiment results show the most appropriate methodology of different commercial software. Finally, conclusions and suggestions are illustrated based on the experiment results.
