摘　　要：实景三维地理场景在利用倾斜摄影模型开展更新时,存在更新模式单一、处理计算复杂等问题。文章针对地理场景数据瓦片式建模的特点,综合模型数据生产组织和时空索引更新处理两个阶段,提出了适用于同类数据增量更新和不同类数据联动更新的技术策略与方法。实验验证表明,文章提出的地理场景更新方法能够适应地形级和城市级模型的快速更新,在工程应用领域具备良好实用性。When using oblique photogrammetry model to update the 3D real scene models,there are some problems such as the limitation of updating mode and the complexity of data processing and calculation.Being directed against the tile structure of 3D scene data,this paper proposes the technical strategies and methods suitable for the incremental updating and the linkage updating by integrating the two stages of data product organization and spatiotemporal index based processing.Experimental results show that the method proposed in this paper can adapt to the rapid updating of terrain-level as well as city-level scene models,and has good practicability.
