基于Lidar数据和倾斜摄影的城市三维模型构建
|
摘要
随着"数字城市""智慧城市"等理念的渗透与创新,城市三维模型这一城市地理信息公共平台建设的核心内容逐渐得到了深入发展,而应用何种建模技术更精准、真实地展现城市空间布局成为国内外各个城市所共同关注的热点问题。论文简要阐述了传统的空间信息获取技术、Lidar系统以及倾斜摄影技术,详细介绍了基于Lidar系统以及倾斜摄影技术的城市三维模型的构建过程。
With the penetration and innovation of the concepts of "digital city" and "intelligent city",the core content of the urban geographic information public platform of the urban three-dimensional model has been gradually developed.Which modeling technology is more accurate and true to show the urban spatial layout has become a hot issue of common concern to all cities at home and abroad.This paper briefly describes the traditional spatial information acquisition technology,Lidar system and tilt photography technology,and introduces the construction of 3d urban model based on Lidar system and tilt photography technology in detail.
