摘　　要：为了提高基于Internet的影像信息服务的速度,提出了相离式金字塔结构,用以组织和管理海量的影像数据;分别讨论了相离式金字塔结构数据和索引两部分的组织问题,并给出了适宜的组织方法。同传统的金字塔结构相比,相离式金字塔结构具有更高的查询响应性能和更好的可扩展性,适于作为影像Internet服务中服务器端的数据组织。In order to improve image service speed based on Internet,we proposed a new architecture for image pyramid,called Separated Pyramid,for organizing and managing huge image data.Separated Pyramid structure contains two parts: data and index,and so we discussed their organization problem,leading appropriate organization for data part and index part respectively.Compared with traditional pyramid structure,Separated Pyramid provides higher query answering and better scalability,and so it can be used as the data organization of the server side in the Internet image service.
