Research in the Topographicmaps Data Acquisition Based on Vehicle-Borne 3D Laser Scanning

文章从三维激光扫描仪在测量中的作用入手,重点介绍了三维激光扫描技术在国内的应用现状,并与传统数据采集方式进行了比较。结合应用实例将三维激光扫描技术应用于大比例尺地形图测量,运用这项技术进行外业数据采集,与传统全站仪数据采集进行了精度比较。结果表明了三维激光扫描技术方案能够克服传统测量方式缺点,保证测绘数据质量,能够提高作业效率。

The article started with the function of three-dimensional laser scanner in measuring. This article mainly intro duces the current situation of 3D laser scanning in China compared with the traditional data -- gathering methods,and ap plication of 3D laser scanning to large scale of topographic survey as well. The technique is used to gather field data. the accuracy can meet the requirements of gathering data when compared with the traditional total station data collection meth od. The technique can overcome the short comings of traditional survey methods, meet the quality requirements and im prove efficiency.
