顾及地物特征的真实感地形显示
首发时间:2008-10-07
摘要:针对使用影像作为纹理映射到DEM上生成真实感地形存在的失真,提出在构建地形模型过程中以地物的边界作为约束条件,同时对地形模型的高程依据地物特征调整,在此基础上进行纹理映射。根据上述方法使用C#和OpenGL生成了真实感地形,结果表明此方法生成的真实感地形可以有效避免部分失真现象。

Realistic Terrain display Considering Landmark Features
Abstract:According to the deficiency of realistic terrain based on Texture Mapping and DEM, A Improvement approach that use landmark boundary as constraints borders for creating CDT and correct the height information of points in boundary of landmark basis on landmark features is proposed. On this basis realistic terrain is created by using Open Graphics Library. New approach shows satisfying results: realistic terrain created with this approach corresponds to the human view of the topography, and avoids some infidelity phenomena.
