Application of 3D Real Scene Technology in Digital Archiving of Dunhuang Yardang Landform
Because of its rarity and uniqueness, Dunhuang Yardang landform has become a typical representative of geological relics, which is a rare and non renewable geological natural heritage. Aiming at the problems of Yardang landform management, protection and non representational reference materials, this paper proposes a method of multi-scale 3D real scene construction based on multi-source data, which not only ensures the reconstruction efficiency, but also enhances the model details compared with the traditional oblique photogrammetry. The model accuracy test shows that 3D real scene construction method proposed in this paper can effectively record the geometric structure and texture details of Dunhuang Yardang landform, and digitally archive the Yardang landform, provi-ding the basis for its repair and reproduction.
