基于空地影像联合的精细化三维建模应用研究

Research on application of refined 3D modeling based on air-ground image

目前,三维数字化建模仍然是有效保护古建筑的重要途径之一。由于古建筑具有结构复杂、构件精细等特性,采用传统的单一数据源方法采集建筑信息所构建的三维模型逐渐难以满足其精细化建模的要求。鉴于此,本文在综述国内外三维实景建模研究现状的基础上,提出了基于空地多源影像联合的实景三维模型建模方法,并对其概念与建模关键技术进行了阐述,从实例角度展现了空地影像联合精细化三维建模技术在建筑领域所取得的成果;同时,对该技术的应用可行性和契合性进行了佐证与分析,以期对古建筑三维模型的精细化建模提供参考。

At present,3 D digital modeling is still one of the important ways to effectively protect ancient buildings.Due to the complex structure and fine components of ancient buildings,the 3 D model constructed by collecting building information using the traditional single data source method is gradually difficult to meet the requirements of its refined modeling.In view of this,on the basis of reviewing the research status of 3 D live-action modeling at home and abroad,a modeling method of 3 D live-action model is proposed based on the combination of air-ground multi-source images,and its concept and key modeling techniques are expounded.From the perspective of examples,the results of the combined refined 3 D modeling technology of air-ground image in the field of architecture are shown.At the same time,the application feasibility and fit of the technology are corroborated and analyzed,in order to provide a reference for the refined modeling of the 3 D model of ancient buildings.
