摘要
智慧城市建设的不断推进,对城市三维模型的需求与应用也提出了更高的发展要求。针对当前城市精细化管理的理念与需求,新型基础测绘体系下智能化全息测绘形成了全要素实景模型这一成果。本文以车载LiDAR采集城市道路红线范围内的三维空间信息,对获取的激光点云数据进行矢量化,得到道路全要素地形数据;基于三维激光点云数据和全要素地形数据生成道路全要素实景模型,实现了各类要素的单体化。该技术路线对相关数据的生产具有一定的参考意义,其成果在城市管理和智能驾驶等领域有着广阔的应用前景。
With the advancement of wisdom city construction,the demand for urban 3 D model and application are also put forward higher requirements for the current urban refinement management concept.In view of the current concept and demand of urban fine management,intelligent perfect-information surveying and mapping under the new basic surveying and mapping system has formed the result of perfect-information real scene model.This paper uses vehicle-borne LiDAR to collect three-dimensional space information within the red line of urban road,vectorizes the obtained laser point cloud data to obtain road perfect-information terrain data,generates road perfect-information real scene model based on the 3 D laser point cloud data and perfect-information terrain data,and realizes the monomer of all kinds of elements.The technical route has certain reference significance for relevant data production,and the results generated have broad application prospects in urban management,intelligent driving and other fields.
