如何实现海量影像数据的合理化存储、高效的访问是视景仿真领域的一个瓶颈问题.本文提出了一种运用SQLite数据库实现基于嵌入式数据库的集中式数据管理方法,将海量影像数据以数据库的形式进行管理,同时又以类似文件操作的方式实现快速访问,为解决基于LOD模式海量影像数据难以管理维护的问题提供了一种可行方案.本文方法有效而稳定地实现了海量影像数据的管理和调度,具有良好的实际应用价值.%How to achieve the rationalization of massive image data storage and efficient access is a bottleneck problem in the field of visual simulation. The SQLite database is used to achieve an embedded database based centralized data management method. The method manages the massive image data using the database and has a way similar to file operation for fast access to solve the problem that the massive image data under the LOD model is difficult to manage and maintain. It is also proved that the method is effective and stable in realizing the massive image data management and scheduling.
