激光扫描是近几年来刚刚发展起来的一种新技术。所采集目标对象的高密度、有精确三维坐标的激光点云,可以广泛应用在整个城市规划工作过程中,因为对于规划工作来说,在三维的虚拟环境中进行分析比依靠二维地图信息要高效得多。本文以国内外的一些实例为基础,介绍了激光扫描技术在城市规划工作不同阶段中的应用,来推进这项技术在我国城市规划中的应用。
Laser scanning is a new technology which has been developed in recent years.With the considerable high point density and explicit 3D coordinates of laser point clouds from objects,it can be widely used in the whole range of urban planning processes,for which analyzing in a 3D virtual reality world is much more efficient than imaging the 2D information on maps.In this paper we analyze laser scanning applications in different urban planning stages,based on some examples at home and abroad,in order to promote the use of this technology in urban planning in China.
