摘要
LIDAR(Light Detection And Ranging)数据作为一种新的数据源应用越来越广泛,LIDAR数据的原始数据一般是离散点数据,而使用LIDAR数据的第一步经常是生成DSM(Digital Surface Model)。目前存在多种利用LIDAR点数据生成DSM方法。但每种方法都有其优缺点,本文将重点对目前广泛使用插值方法进行分析比较,从而为实际应用挑选同插值算法提供帮助。
As a new data source, LIDAR（Light Detection And Ranging） data has more and more applications. LIDAR is not the same as imagery,it generates a high spatial resolution ＂point cloud＂. To use it,the first step generally is to translate it to Digital Surface Model（DSM）. Although there are many ways can be used to generate DSM at present,each of them has its advantages and disadvantages, This paper analyzes some main methods of interpolating DSM , and the analysis will provide very useful references for the practical applications.
