无人机倾斜摄影三维建模的工程量计算及管理差异研究

AUTOMATIC ENGINEERING QUANTITY CALCULATION AND MANAGEMENT DIFFERENCE ANALYSIS BASED ON 3D MODELING OF UAV OBLIQUE PHOTOGRAPHY

以某公路工程为例,提出基于无人机倾斜摄影三维建模的工程量自动计算及管理差异性分析方法,确定无人机倾斜摄影像控布点后采集工程的实景信息,构建无人机倾斜摄影技术的工程三维模型;并在此基础上构建基于BIM的工程量自动计算以及管理差异性分析模型,实现工程量自动计算和管理差异性分析,该方法具有较好的应用效果。

Taking a highway project as an example,an automatic engineering quantity calculation and management difference analysis method based on UAV oblique photography 3D modeling is proposed.After determining the control point of UAV oblique photography,collecting the real scene information of the project,constructing the engineering 3D model of UAV oblique photography technology.On this basis,a BIM based en�gineering quantity automatic calculation and management difference analysis model is constructed to realize the automatic engineering quantity calculation and management difference analysis.The method has a good application effect.
