| Abstract: | In the urban real scene 3D construction, scene fusion of multi-source and multi-scale real scene 3D data can further improve the detail expression of real scene 3D, improve the integrity of urban real scene 3D, and meet the requirements of local update mechanism of real scene 3D. This paper has carried out relevant research on massive, heterogeneous and multi-scale real scene 3D fusion technology and methods, explored and improved the spatial accuracy matching and data edge connection methods of multi-source real scene 3D data, combined with the standardized and lightweight processing methods of real scene 3D data results, improved the scheduling and display efficiency of real scene 3D scenes, and further expanded the application field of real scene 3D fusion results. |
