一种从农村地区Lidar数据中自动提取DEM的算法

Algorithm to generate DEM in rural areas from Lidar data

根据激光雷达数据的特点以及农村地区地形的特点,提出了一种融合Lidar距离数据和强度数据的自动提取数字高程模型(DEM)的算法。运用此算法对某地区的激光雷达数据进行了试验,证明该算法的可行性。

Based on the character of Lidar data in rural areas,a new algorithm which is fusion the range information and intensity information is proposed.This paper comes to a conclusion that it is theoretical and practical significance that this method is used to study the Lidar data of a rural area.
