倾斜摄影测量在建筑附属设施施工中的应用

Application of Oblique Photogrammetry in Construction of Building Auxiliary Facilities

以某图书馆的雨棚为例,首先利用消费级无人机采集雨棚的数据信息,再通过Smart-3D软件构建雨棚三维模型,然后分别量测三维模型和实际雨棚框架的检查点来分析精度,最后利用EPS软件勾画龙骨框架,利用AutoCAD软件生成并导出最终模型。结果表明,通过无人机倾斜摄影测量的方法可有效获取建筑附属设施的尺寸信息,其结果既符合GB 50026-2007《工程测量规范》的相关要求又提高了工程建设效率,可为其他相关的工程建设提供参考。

Taking a library canopy for example,we used consumer UAV to collect canopy data information,and used Smart-3D software to build the 3D model of canopy at first.Then,we measured the checkpoints of the 3D model and actual canopy frame respectively to analyze the accuracy.Finally,we used EPS software to sketch the keel frame,and used AutoCAD software to generate and export the final model.The experimental results show that the size information of the building auxiliary facilities can be effectively obtained by the oblique photogrammetry of UAV The results are in line with the relevant requirements of Code for Engineering Surveying,and improve the efficiency of the project construction,which can provide a reference for other related engineering construction.
