Fine modeling of large urban area based on tilt photogrammetry
Aiming at the problems of building surface distortion and void in 3D real-life model building by tilt photogrammetry technology of unmanned aerial vehicle,this paper proposes to use DP-Modeler and manual repair survey to make up the model defects and realize the fine modeling of 3D real-life model in large area.The results show that UAV tilt photogrammetry has the advantages of high efficiency and low cost for the construction of large-scale three-dimensional real-life model in cities,and the model optimization effect can be achieved by refining and repairing the model.
