基于四叉树技术的全球影像数据组织管理关键技术研究

On the Key Technologies of Quadtree-based Global Image's Organizing and Management

人们获取影像数据能力的极大提高,带来了对海量影像数据高效组织管理的需求.本文提出一种基于四叉树技术的海量空间数据管理技术,用于实现全球影像数据的组织管理,重点阐述了其中的影像金字塔反向构建、投影和影像整合等关键技术,并给出了实例说明该技术的可行性.

With the capacity of acquiring the image date improved,it brings need for the high-performance on massive image data organization and management.This paper has presented a quadtree-bassed massive spatial data management technology,which is helpful for organizing and managing global image data.This paper focuses on some key technologies,such as reverse construction of image pyramid,projection,image integration,etc.Then an example of the technical feasibility has been given.
