| 摘 要： | 无人机影像自动恢复三维场景所需的数据种类多、数据量大、结构复杂,如何高效一体化组织管理数据成为恢复三维场景系统的关键。从数据库的概念模型、逻辑模型和物理模型出发,开发一套高效的三维场景数据库管理系统,根据地物的特点对地物模型设置点位坐标和方位坐标,并设计出相应的数据存储表结构,有效解决地物模型自动精确置入地形模型的问题。最后通过海南省某条铁路线段数据进行验证,实验结果表明该数据库的有效性。

| Abstract: | UAV image can automatically recover 3D scene, which needs a large variety and number of data, and complicated structure, And to organize and manage data in hige efficience and integration becomes the key to recover the 3D scene system.This paper, starting from analysis of concept model,logical model and physical model of database, designs an efficient management system for 3D scene database.According to the characteristics of ground object, it sets point coordinate and azimuth coordinate of terrain model, and devises a corresponding data storage table structure.By this way, it can help ground object model imbedded into terrain model automatically and accurately.Finally the data in some railway of Hainan Province are used to verify the validity of this database. |
