基于激光三维扫描技术的一种分类出地面点的方法

激光三维扫描技术可以直接获取地面三维数据,比传统测量方法具有高精度、高密集、高效率和成本低的优点.数据的分类是激光三维扫描技术中的关键问题之一.本文通过反复建立三角形的过程分类出地面点,并在实例中应用,效果良好.本方法简单易行,但是还存在着一些缺点有待改进.

A Method for Classifying Ground Data Based on the Airborne Laser Scan System

The airborne laser scan system for acquiring 3D terrain data directly is better than the conventional survey.There are the advantages of high precision,high density,and high efficient and low cost.The data classification is one of the central problems of this system.In this paper,ground data is classified by an iterative process which builds a triangulated model and molds it upwards.This method has used in an example and it had a good result.The method is simple,but it still needs to be improved.
