背包式激光扫描系统的地下空间数据获取方法模式研讨

Discussion on the method pattern of underground space data acquisition in backpack laser scanning system

结合控制测量的导线理论研究了移动背包三维激光扫描系统的pure SLAM和fused SLAM作业方法,并在轨道交通工程竣工测量工作中应用两种方法共4种模式分别进行施测,分析出最佳作业方法模式,实现快速的、高精度的点云数据获取。研究分析结论对应用移动三维激光扫描系统实现快速获取地下空间信息数据具有一定的借鉴意义。

The pure SLAM and fused SLAM operation methods of 3 D laser scanning system of mobile backpack are studied in combination with the traverse theory of control surveying.In the completion survey of rail transit project,four modes in two methods are applied respectively,and the optimal operation mode is analyzed to realize fast and high precision point cloud data acquisition.The conclusion of the research has certain reference significance for the application of mobile 3 D laser scanning system to realize the rapid acquisition of underground spatial information data.
