摘要

激光雷达数据是获取DEM的新来源。本文提出了一种利用该数据源获取DEM的方法，该方法首先对末回波和单回波进行筛选，然后建立TIN，获取各点附近点的信息进行滤波，最后去除孤立点，生成DEM。实验结果表明，该方法是可行和有效的。

A method of deriving DEM from airborne LiDAR points cloud data

LiDAR data is the new source of obtaining DEM. In this paper, an acquiring DEM method using this data source is promoted, which firstly screens the last and single return waves, then builds TIN to acquire the nearby points' information of each point which helps filtering, lastly removes the isolated points and generates DEM. The experimental results show that this method is available and effective.
