摘要
倾斜摄影是一种通过多镜头对多角度数据进行获取的测量方式,能够建设出真实纹理的三维场景。该方法突破了常规航空摄影仅能从一个方向进行拍摄的限制。然而,现有基于倾斜影像数据的三维建模方法大多为一个连续整体,无法操作和管理单独目标,例如属性查询、建筑物选取、空间查询等。当前,三维场景建模仍处于相对简单的空间解析、视觉浏览等方面,无法充分利用倾斜影像的优势。因此,开发成本低、速度快的单体化方法是当前研究的重点。本文对三维模型单体化、单体化模型数据管理分类和应用、城市三维建模及实体化等展开了深入研究与探讨,提出了倾斜摄影三维模型单体化及智慧城市应用策略,为实现现代化城市的智能化和精细化管理奠定基础。
Oblique photography is a kind of measurement method to obtain multi-angle data through multiple lenses,which can build a three-dimensional scene with real texture.This method breaks through the limitation that conventional aerial photography can only be taken from one direction.However,most of the existing 3D modeling methods based on oblique image data are a continuous whole,which cannot operate and manage individual objects,such as attribute query,building selection,space query,etc.At present,3D scene modeling is still in relatively simple spatial analysis,visual browsing and other aspects,which can not make full use of the advantages of oblique image.Therefore,the development of low-cost and fast monomer methods is the focus of current research.Therefore,this paper carries out in-depth research and discussion on the monomer of 3D model,the classification and application of monomer model data management,urban 3D modeling and materialization,and also puts forward the monomer of oblique photography 3D model and the application strategy of smart city,laying the foundation for the realization of intelligent and fine management of modern city.
