南方古建筑翼角结构的参数化建模方法研究

Research on Parametric Modeling Method of Wing Angle Structure of Southern Ancient Buildings

南方古建筑翼角结构复杂,基于测绘的3D重建工作极易在结构的准确性上产生偏差。文章依据中国古建筑文献《营造法原》对南方古建筑翼角结构特征的记述,提出了基于参数化技术的古建筑翼角结构快速3D重建方法。该方法构建古建筑翼角的3D参数化模板,以有限的测绘数据为输入,实现快速建模,给出了翼角结构参数以及翼角上的10类构件的参数化定义方法,并基于实地测绘与3D重建项目对该法进行了应用测试。

The wing angle structure of ancient buildings in the south is complicated, and the 3D reconstruction based on surveying and mapping is likely to cause deviations in the accuracy of the structure. Based on the description of the ancient building wing angle structure characteristics in the ancient Chinese building document "Building Law", a fast 3D reconstruction method of the ancient building wing angle structure based on parametric technology was proposed. This method constructs a 3D parameterized template of the ancient building’s wing angle, and uses limited surveying and mapping data as input to achieve rapid modeling. The wing angle structural parameters and the parameterized definition method of 10 types of components on the wing angle are given. The method was tested on the basis of field surveying and 3D reconstruction projects.
