摘要: 在城市级实景三维建设中,对多来源、多尺度实景三维数据进行场景融合,能够进一步完善实景三维场景细节表达,提高城市级实景三维场景的完整性,满足实景三维场景局部更新机制要求。本文针对海量、异构、多尺度实景三维融合技术方法开展了相关研究,探索并改进了多源实景三维数据的空间精度匹配与数据接边的方法,结合实景三维数据成果的标准化、轻量化处理方法,提升了实景三维场景调度显示效率,进一步扩大了实景三维融合成果的应用领域。

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.

Key words: real scene 3D, multisource and isomerism, 3D Tiles, scene fusion, data lightweight
