Low-altitude UAV 3D modeling technology in the application of ancient buildings protection situation assessment

Based on low-altitude UAV remote sensing technology to quickly build 3D models of ancient architecture. Not only can truly record of the monomer building shape, color, texture, style, damage, structural features, and can truly record of the entire distribution patterns of village buildings, roads and other information surrounding terrain. On one hand, the status information of ancient relics can be recorded rapidly, massively, incoherently, on the other hand, work and assessment efficiency of heritage conservation staff and government departments can be greatly improved.
