摘要
介绍了移动测量系统的系统构成、工作原理以及该系统的误差来源,通过对贵阳市中环路竣工测量中的数据采集流程进行介绍,研究了POS数据处理、全景影像拼接、图形编辑、特征和线状地物提取、数据建模等关键技术,通过点云数据和实地采集点位进行精度的对比分析,验证了三维激光扫描技术应用于测制大比例尺地形图的可行性、技术优势。
This paper introduces the system structure,working principle and the error source of the mobile measurement system used in this project,and introduces the data collection process in Guiyang middle ring road completion survey,and studies the POS data processing,panoramic image splicing,graphic editing,feature extraction and data construction,Through the comparison and analysis of the precision of the point cloud data and the spot location,the feasibility and technical advantages of the 3 D laser scanning technology used in the large scale topographic map are verified.
