| 摘 要： | 论述了SQL Server Spatial技术理论,探讨了空间数据导入、索引的创建以及空间数据的查询方法。并以3维激光扫描获取的点云数据为例,采用C#连接SQL Server数据库,对点云数据进行了组织及查询,并在MapOb-ject组件下进行可视化。试验证明,建立空间索引后点云数据的检索效率较高。

| Abstract: | This paper discusses the theory of SQL Server Spatial technology,and demonstrates the method of spatial data import,index creation,and spatial data query.Taking the point cloud data obtained by 3D laser scanner as an example and using C# to connect SQL Server database,the author organizes and queries the point cloud data and visualizes it in MapObject components.Experiment proves that point cloud data retrieval efficiency is higher after building spatial index. |
