基于机载LiDAR数据的区域林木信息提取

Tree information extracting based on LiDAR data

本文对LiDAR数据的各种滤波方法以及多次回波特性进行了综合研究,提出一种基于其多次回波特性进行林木信息提取的方法,并对该方法的可行性进行了实例验证,为探索LiDAR数据的应用提供了新的思路。

The hardware of airborne LiDAR technology has been relatively mature in foreign countries, but the data post-process- ing and applications of LiDAR data are still on research and development stage. In this paper, basing on the comprehensive study of Li- DAR data filtering methods and the various characteristics of a multiple echo, a method to extract the information of trees was developed and carried out. Compared with traditional visual interpretation method, the method＇s feasibility was verified and also it could provide a referential way to explore the applications of LiDAR data.
