| 摘 要： | 通过设计具有线性相位和对称性的紧支双正交小波来提取同一地形区域上的多分辨分析模型,并建立基于四叉树结构的数据库.结合人眼视觉的限制,对敏感地区的地表用高分辨率数据显示,对不敏感地区的地表则用低分辨率数据显示.这样图像的数据量就会大大减少,可以加快三维地表模型的显示速度.

| Abstract: | Through designing linearity phase and symmetry biothogonal compact wavelet the multi-resolution analysis model of the same topographical area is abstracted, then the database of quadtree-based structure is set up . Combine the restriction of human eye vision, the terrian of sensitive area is displayed with high-resolution data and the terrian of no sensitive area is displayed with low-resolution data. In this way the data amount of picture will be reduced greatly, it can accelerate the speed of displaying for the three-dimensional terrian model . |
