三维激光扫描仪应用技术研究

摘要:三维激光扫描是近年来迅速发展起来的一种新型空间数据获取手段和工具,利用地面三维激光扫描系统可以快速、准确地进行城市三维重建,因而在城市建模研究与应用方面受到越来越广泛的关注。本文以三维城市建模中的建筑物为研究对象,探讨如何利用三维激光扫描仪获取空间数据并建立相应地物模型的技术方法。

Abstract: The three-dimensional laser scanning is a new type of spatial data access method and tool which is rapidly developing in recent years, with ground-dimensional laser scanning system, it can reconstruct the city with three-dimensional quickly and accurately, so it gained more widespread concern in urban modeling research and applications. In this paper, taking three-dimensional modeling of buildings as research object, how to use three-dimensional laser scanner to obtain the corresponding surface features of spatial data and building models of technical methods is discussed.
