3D SLAM背包式扫描仪在旧建筑改造辅助测量中的应用

Application of 3D SLAM Backpack Scanner in Auxiliary Measurement of Old Building Reconstruction

基于3D同步定位与建图(3D simultaneous localization and mapping,3D SLAM)技术的背包式扫描仪,以旧建筑地下室和地上主体改造辅助测量项目为依托,介绍了该项目的作业流程,并利用人工量尺方式对点云量测结果进行精度评定,结果表明,所取得成果精度约为0.02 m,基本能满足一般工程测量精度需求。同时,实验验证了3D SLAM技术在特定场景下的可行性及优越性。

This project uses a backpack scanner with 3D SLAM technology.Based on the auxiliary measurement of the old building reconstruction of the main body,this article introduces the operation process of the project,and uses manual Measurements to evaluate the accuracy of the point cloud measurement results.Experiments show that the accuracy of the results is about 0.02 meters,which can basically meet the general engineering measurement accuracy requirements.At the same time,the feasibility and advantages of 3D SLAM technology in specific scenarios were verified.
