摘　　要：针对大比例地形图采用传统方法绘制存在外业工作量大、获取数据不全面、数字化智能化低等问题,如何在保证精度的前提下快速获取地形图数据,提高成图效率,降低劳动强度,是测绘行业的新挑战。本文利用GeoSLAM手持移动扫描仪对前门东路区域进行三维激光扫描,采用清华山维EPS软件进行地形图绘制。通过全站仪极坐标法对特征点校核,精度满足规范要求。测试结果表明:采用手持移动扫描仪进行大比例尺地形图测绘,可以节约人力成本,提高了生产效率,满足大面积地形图快速成图的要求。In view of the problems of large scale topographic map drawing by traditional method,such as large field workload,incomplete data acquisition and low digital intelligence,how to obtain topographic map data quickly,improve mapping efficiency and reduce labor intensity under the premise of ensuring accuracy,is a new challenge for the surveying and mapping industry.In this paper,the GeoSLAM handheld mobile scanner was used for 3 D laser scanning of the area of East Qianmen Road,and the topographic map was drawn by the EPS software of Tsinghua Mountain Dimension.Through polar coordinate method of total station to check the feature points,the accuracy meets the specification requirements.The test results show that the use of handheld mobile scanner for large scale topographic map mapping can save labor costs,improve production efficiency,and meet the requirements of rapid mapping of large area topographic map.
