摘要
以济南市高新区舜泰广场一号楼周边为研究区域,对LiBackpack DGC50背包三维激光扫描系统技术参数、关键技术、工作原理及工作流程进行了介绍,重点通过数据采集对该仪器进行了精度验证。结果表明,该系统比传统全站仪、RTK作业方法在作业效率上显著提高,点位精度和距离精度均小于5 cm,可以满足大比例尺地形图测绘的要求。
This article takes the area around No.1 Building of Shuntai Plaza in Ji′nan High-tech Zone as the research area,and introduces the technical parameters,key technologies,working principles and workflow of the LiBackpack DGC50 backpack 3D laser scanning system,and verifies the accuracy of the instrument through data acquisition.The results show that the system is significantly more efficient than the traditional total station and RTK operation method,and the point position accuracy and distance accuracy are both less than 5cm,which can meet the requirements of large-scale topographic map surveying and mapping.
