【摘要】：在对传统的分层设色晕渲理论应用于城区DSM的可视化技术进行充分研究的基础上,提出了一种基于高程直方图的自适应高程分级方法。该方法通过高程直方图研究城区地形、地物的高程分布及变化特征,自适应建立高程带分级模型。实验表明,提出的晕渲图制作方法兼顾了地貌形态和地物特征的表达,成果色彩过渡自然,层次清晰,地形、地物区分明显,有较强的艺术性和实用价值。
[Abstract]:An adaptive elevation classification method based on elevation histogram is proposed on the basis of the full study of the traditional theory of layering shading and shading applied to the visualization technology of DSM in urban area. The elevation histogram is used to study the elevation distribution and variation characteristics of urban terrain and objects, and an adaptive elevation classification model is established. The experiment shows that the method of making shading map takes into account the expression of geomorphology and features of landform and features, the result is natural in color transition, clear in layer, distinct in terrain and feature, and has strong artistic and practical value.
