基于倾斜摄影测量的城市大区域精细化建模

Fine modeling of large urban area based on tilt photogrammetry

文章针对无人机倾斜摄影测量技术在三维实景模型建立中存在建筑物表面失真、空洞等问题,提出采用DP—Modeler及人工修补测的方式弥补模型缺陷,实现三维实景模型的大区域精细化建模。结果表明,无人机倾斜摄影测量对于城市大范围三维实景模型建设具有高效、低成本的优势,通过对模型精细化修补测可达到模型优化效果。

Aiming at the problems of building surface distortion and void in 3D real-life model building by tilt photogrammetry technology of unmanned aerial vehicle,this paper proposes to use DP-Modeler and manual repair survey to make up the model defects and realize the fine modeling of 3D real-life model in large area.The results show that UAV tilt photogrammetry has the advantages of high efficiency and low cost for the construction of large-scale three-dimensional real-life model in cities,and the model optimization effect can be achieved by refining and repairing the model.
