Application of Oblique Photogrammetry Technology in Topographic Mapping
Abstract：Based on the application of oblique photogrammetry technology in topographic mapping, this paper selects a certain area in Nanjing as the study region. Data collection was carried out using the DJI Matrice 300 RTK drone, and 3D modeling was completed by combining Context Capture software. The digital topographic map was drawn using Southern CASS 3D software. The research adopts a 'bow' shaped flight path design, and studies the processes of aerial triangulation, dense matching, and 3D model generation. The accuracy test shows that the error meets the specification requirements. The results of this study verify the advantages of oblique photogrammetry technology in complex terrain environments, providing effective data support for urban planning, infrastructure construction, and other fields.
