摘要
随着信息化发展,如何快速、高效、方便地获取及处理专题数据是一个迫切需要解决的问题。该文主要阐述了车载移动测量系统的组成和工作原理,利用车载移动测量系统提取城市专题数据的作业流程。探讨了利用车载激光移动测量系统,通过对道路两旁区域进行自动化和高效率数据采集,根据采集的全景影像和点云数据,对城市道路、建筑、树木和路灯这几类专题数据进行半自动或手动提取来获得各类专题数据的方法。
With the development of information technology, how to obtain and deal with the thematic data quickly, efficiently and conveniently is an urgent problem. This article mainly elaborates the constitu- tion and working principle of the vehicle-borne mobile mapping system and the working process of extrac- ting the thematic data of city by using the vehicle-borne mobile mapping system. The automatic and effi- ciently data collection for the area of both sides of the roadis carried out by using the vehicle-borne laser mobile mapping system based on the collected panoramic image and point cloud datea, the method of au-to-extracting or semi-auto-extracting the thematic data such as the urban road, building, tree and street lamp are obtained.
