This paper presents the results of a complex three-dimensional reconstruction of the church of Nuestra Señora de la Asunción (Ávila, Spain) as an example of a successful process of verticalization from point clouds to a comprehensive computer-aided design (CAD) model. The reconstruction was carried out using the novel and advanced wearable mobile mapping system ZEB-REVO in combination with a lifting pole, in order to cover the whole geometry of the temple and, also, to model the different constructive elements. To this end, a set of good practices was followed, which allowed for passing from reality to the CAD model, such as the use of closed loops or even the use of different parametric and non-parametric strategies to capture the real geometry of the elements. As a result, this paper outlines the main guidelines for passing from point clouds to comprehensive CAD models, the former being useful for the application of smart preventive conservation processes, heritage building information models or even advanced numerical simulations.
本文以西班牙阿维拉的圣母升天教堂为例,展示了将点云进行复杂的三维重建,并成功转化为全面的计算机辅助设计 (CAD) 模型的过程。重建使用了新型的先进可穿戴移动测绘系统 ZEB-REVO 与升降杆相结合,以覆盖整个教堂的几何形状,并对不同的建筑元素进行建模。为此,遵循了一套良好的实践方法,从现实到 CAD 模型的转化,例如使用封闭回路,甚至使用不同的参数化和非参数化策略来捕捉元素的真实几何形状。因此,本文概述了从点云到全面 CAD 模型的主要指导方针,前者可用于应用智能预防性保护流程、文物建筑信息模型甚至高级数值模拟。
