摘要
基于尝试动态三维激光扫描技术替代传统测绘技术的目的,以宁波市轨道交通2号线高架区间规划竣工测量项目为例,采用并融合GPS、POS、IMU、三维激光扫描、点云处理等技术,着重讨论了车载扫描野外数据采集及处理、三维点云数据向二维成果转化的过程及方法,最后通过与传统方法的对比验证,得出新方法可行的结论。
Dynamic 3 d laser scanning technology based on trying to replace the traditional surveying and mapping technology,the purpose of the rail transit line no.2 in ningbo elevated range planning completed measuring project as an example,using GPS,POS,innovative marketing and fusion,3 d laser scanning,point cloud processing,such as technology,emphatically discusses the on-board scanning field data acquisition and processing,3 d point cloud data to the 2 d achievements transformation process and method,at last,by comparing with the traditional method validation,come to the conclusion that the new method is feasible.
