遥感影像剖分金字塔研究
分析了全球剖分格网与影像金字塔的优点与不足,结合两者的优势提出了剖分影像金字塔模型及建塔策略,利用全球剖分格网面片编码的唯一性和Hilbert曲线空间连续性对影像块进行索引与组织.针对基于影像块组织的特点,提出了剖分影像金字塔局部更新的方案.实验结果表明,剖分影像金字塔不仅具有传统影像金字塔在快速浏览上的优势,并且由于其编码和索引的优势,使得在局部影像提取和更新方面效率更高,有一定的使用价值.
Remote Sensing split Pyramid Research analyzes the advantages and disadvantages of global subdivision grid and image pyramid, combining the advantages of both proposed split image pyramid model and strategy to build towers, use of global subdivision grid patch coding Uniqueness Hilbert curve and spatial continuity of the image block indexing and organization. based on the characteristics of the image block for the organization, proposed a partial update of the split image pyramid scheme. the results show that not only has the traditional split image pyramid image on pyramids in Quick View advantages, and because of its advantages coding and indexing, so higher extraction efficiency and updating local image, there is a certain value.

利用地球立体剖分格网生成SubdivisionR_树索引模型
针对三维数据管理中八叉树索引冗余多、R-树索引插入删除过程复杂的问题,依托GeoSOT地球立体剖分格网,提出了一种新的八叉树与R-树有机结合的Subdivision R-树索引模型(Subdivision R-tree)。首先,以GeoSOT地球立体剖分格网八叉树索引为基础构建了Subdivision R-树索引模型结构 随后,设计了Subdivision R-树索引模型基本的插入、删除、查询、分析算法 最后,开展了Subdivision R-树索引与原有数据索引性能对比试验,并对Subdivision R-树的阈值选取进行了相应分析。
The use of three-dimensional Earth subdivision grid generation SubdivisionR_ tree indexes for multi-dimensional data model redundancy management octree index, R- tree indexes insertion and deletion process complex issues, relying GeoSOT Earth perspective subdivision grid, proposed a Subdivision R- tree indexes new model octree and R- tree organic combination (Subdivision R-tree). First, the Earth' s perspective GeoSOT octree subdivision grid based index constructed Subdivision R- tree indexes model structure subsequently, the basic design of the insertion Subdivision R- tree indexing model, delete, query, analysis algorithm and finally, to carry out Subdivision R- tree indexes with the original data indexing performance comparison test, and the threshold Subdivision R- tree analysis of selected accordingly.
