| 摘 要： | 山脊线和山谷线的提取意义重大,研究的方法也很多。本文提出一种新的地性特征线的提取方法———垂直剖面法。该方法针对山脊线和山谷线的地性特性,构造垂直剖面线,在山体延伸方向上截取一系列的点,对邻近的高程值相等的各点进行合并筛选,采用各点比较的方法获取特征点,建立数学模型对其特征点进行匹配,获取地性特征线。

| Abstract: | It is of great significance to extract ridge and valley, so there are a lot of methods to study.In this paper,a new method for automatic extraction of topographical feature lines—vertical sectional method is proposed.Aiming at the topographical feature of ridge and valley,this method constructs vertical section lines,and intercepts a series of points in the trend direction of the contours.Neighbor points which have equal altitude value are merged and filtered,thus,we can get feature points through comparison and set up a mathematical model to match feature points.Finally,topographical feature lines are gained. |
