激光扫描与无人机空地一体融合测量应用

测量是工程项目建设的重要基础，贯穿从规划设计、施工到竣工整个工程建设的全生命周期。近年来，越来越多的工程开始考虑全流程利用数字孪生进行项目管理应用。传统的测量方法存在外业周期长和成果抽象难等缺点，难以进行可视化表达。本文利用Trimble SX10三维影像激光扫描仪结合无人机进行空地一体融合测量，并总结了相应的技术方法和流程。与传统测量手段相比，本文方法不仅缩短了测绘周期，解决了夜间光学测绘的难题，成果还可数字可视化表达。

Application of laser scanning and UAV air-ground integrated measurement

Surveying and mapping is an important part of the construction of projects, which runs through the entire life cycle of the entire project construction from planning, design, construction and completion. In recent years, engineering has begun to consider the whole process of using digital twins for project management applications.Traditional measurement methods have the defects of need long work time and single results,and it's difficult to visualize. In this paper, Trimble SX10 3D image laser scanner and UAV are used for air-ground integrated measurement, the corresponding technical methods and processes are summarized, which not only shortens the mapping cycle compared with traditional measurement methods, and the problem of night optical mapping is soved, but also the results can be digitally visualized.
