Abstract:

Realistic 3D modeling is the digital base for the construction of digital economy and digital engineering. This paper introduces the key technologies and control of the overall relocation and protection of “Yangtze River Estuary II” ancient ship during the process of image acquisition and realistic 3D modeling using the oblique photography technology of unmanned aerial vehicle (UAV), analyzes the accuracy of aerial triangulation in realistic 3D modeling, and finally discusses the visual display and application of the real-time 3D model through the Web 3D GIS platform.

Key words: unmanned aerial vehicle (UAV), oblique photography, realistic 3D, visualization
