摘　　要：智能交通理念的不断发展,对城市道路地形图的需求提出了更高的要求。为进一步实现城市道路的精细化管理,本文在分析了传统道路地形图的不足的基础上,阐述了车载激光点云的新型测绘技术的基本原理和特点;详细论述了道路全要素地形图中典型要素的采集规则、采集方法,利用EPS软件对获取的点云数据进行道路全要素矢量化。为提高道路全息矢量提取效率和准确性,结合矢量提取难点,利用EPS脚本管理器进行二次开发,实现了图形批量编辑、属性批量赋值、数据检查等功能的二次开发,大大提高了道路全要素地形图的生产效率。The continuous development of intelligent transportation concept puts forward higher requirements for the demand of urban road topographic map.In order to further realize the fine management of urban roads,based on the analysis of the shortcomings of traditional road topographic map,this paper expounds the basic principles and characteristics of the new mapping technology of vehicle-borne laser point cloud.The collection rules and methods of typical elements in the road all element topographic maps are discussed in detail.The obtained point cloud data is vectorized by EPS software.In order to improve the efficiency and accuracy of road holographic vector extraction,combined with the difficulties of vector extraction,EPS script manager is used for secondary development,which realizes the secondary development of graphic batch editing,attribute batch assignment,data inspection and other functions,which greatly improve the production efficiency of road all element topographic maps.
