移动测量、地理信息更新与城市管理智能化

摘要

The foundation of urban management intelligence is internet,geographic information platform and cloud computing platform.Data updating is the soul of geographic information platform.The rapid updating of urban geographic information involves concepts,funds and techniques.These three factors constitute the historic challenge of urban surveying and mapping,and also the reality bottleneck of the implementation of urban management intelligence.This paper presents a city natural data model (CNDM) that is based on the color laser point cloud.Based on vehicle borne mobile mapping,unmanned aerial vehicle (UAV) aerial photograph,mobile phone taking,HD video surveillance and cloud computing platform,a fast updating system of CNDM is formed.City geographic information platform for city actuality is constructed based on the real-time update of CNDM,which is to establish the base data of urban management intelligence.%城市管理智能化的基础是互联网、地理信息平台和云计算平台.地理信息平台的灵魂,是其数据的现势性.城市地理信息快速更新,涉及理念、经费和技术,这3个要素构成了城市测绘的历史性挑战,也是城市推行智能化管理的现实性瓶颈.本文提出基于真彩激光点云,构建一种城市自然数字模型;基于车载移动测量、无人机航摄、手机拍照、高清视频监控及云计算平台等技术手段,形成城市自然数字模型快速更新的技术体系;以实时更新的城市自然数字模型,构建具有最优现势性的城市地理信息平台,即以此奠定城市管理智能化的数据基础.
