Abstract:

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.
