Derivation of valley line and ridge line by segmental cubic polynomials;
利用分段三次多项式提取山谷线和山脊线
A ridge line extraction algorithm is proposed based on DEM according to the characteristic of the terrain,firstly,the algorithm fills depressions and smoothes the terrain efficiently,then extracts the ridge line and thins it,lastly,the main ridge line is extracted to meet the requirement of the occlusion culling.
针对大规模复杂地形的特点,提出了一种有效的基于规则网格的地形主山脊线特征提取算法。
The usual method for extracting ridge line and valley line is based on geometric and physical character which is difficult to use the information hiding in the digital data.
针对当前山脊线和山谷线的提取都是从其几何特征或物理特征的单一方面进行研究和设计,不能够利用隐含在数字化资料中的山脊线和山谷线的有效信息的弊端;本文利用几何分析方法Douglas-Peuker提取山脊线和山谷线的特征点,并结合提取区域内地形概略的分水线和汇水线,用概略的分水线和汇水线对特征点进行识别、归类、顺序提取各条山脊线和山谷线,把山脊线的几何特性与物理特性结合起来,克服了各自的弊端。
