地面三维激光点云数据在桥梁勘察设计中的运用

Application of Ground Laser Point Cloud Data in Bridge Survey and Design

传统桥梁勘察需要深入现场逐点测量,不仅人力物力花费高效率低,而且勘察质量受测量人员技术水平影响较大。针对这种情况,本文对基于无人机进行的三维激光点云测量手段进行了详细介绍,然后以两个工点为例,通过实验获取三维激光点云数据,并将处理结果与传统现场实测数据进行对比分析,验证了基于无人机航测的智能勘察在桥梁勘察设计中的应用可行性。

Traditional bridge surveying requires engineering surveys at every point on the site,which not only cost high manpower and material resources,but also survey quality is greatly affected by the technical level of the surveying personnel.In response to this situation,this article introduces the laser point cloud measurement method based on unmanned aerial vehicle in detail,and then takes two typical construction sites as examples to obtain laser point cloud data through experiments,and compares them with the traditional field measurement results.By comparing and analyzing the data,the feasibility of using the ground laser point cloud data in bridge survey and design is verified.
