| 摘 要： | 目的 针对DEM建模及三维可视化时间过长的问题,提出一种缩短DEM建模及三维可视化时间的方法.方法 采用改进Delaunay三角网构建DEM,在ImageJ中实现其三维可视化.结果 笔者提出的改进算法建模时间低于基于分治算法和基于凸包算法建模,在实现DEM三维可视化上,利用ImageJ完成的速度快于利用OpenGL、Direct3D和VRML实现的三维可视化.结论 通过对不同数量样本点的测试分析,该算法缩短了DEM建模时间,同时加快了DEM三维可视化的速度.

| Abstract: | It is excessive on costing time of building Digital elevation model (DEM) and realizing its three-dimensional visualization,therefore,an optimal algorithm is designed to build DEM and realize its three-dimensional visualization.This paper proposes a research on building DEM and realizing its three-dimensional visualization base on ImageJ by applying improved Delaunay triangular net.The time-consuming on the improved algorithm of Delaunay triangular net to build DEM is less than those of the partition-based ... |
