Detailed Primitive-Based 3d Modeling of Architectural Elements

Abstract

ABSTRACT:The article describes a pipeline, based on image-data, for the 3D reconstruction of building façades or architectural elements and the successive modeling using geometric primitives. The approach overcome some existing problems in modeling architectural elements and deliver efficient-in-size reality-based textured 3D models useful for metric applications. For the 3D reconstruction, an opensource pipeline developed within the TAPENADE project is employed. In the successive modeling steps, the user manually selects an area containing an architectural element (capital, column, bas-relief, window tympanum, etc.) and then the procedure fits geometric primitives and computes disparity and displacement maps in order to tie visual and geometric information together in a light but detailed 3D model. Examples are reported and commented.

“…They highlight the need for adaptive levels of detail that align with the context and requirements of each project, emphasizing the importance of precision in models to closely reflect reality. Similarly, Remondino et al (2012) focus on the importance of lightweight models for effective manipulation and visualization, addressing the need for practical, user-friendly solutions in the preservation and study of heritage buildings. Finally, Rocha et al (2020) draw attention to the difficulty of the scan-to-BIM process, which requires a comprehensive set of skills throughout the workflow.…”

“…This approach captures more than geometry; it highlights the historical and architectural essence of each element. De Luca et al (2007) and Remondino et al (2012) have emphasized the creation of libraries of elements and primitive-based 3D modeling, focusing on the semantic understanding of architectural elements, underscoring the need for a comprehensive approach that blends the geometric fidelity with rich historical insights. The challenges in applying BIM to existing buildings, particularly historic structures, are manifold, including high modeling costs, data uncertainty, and the necessity for detailed levels of data capture.…”

“…Moreover, another two lines of research have also been carried out that are worth mentioning: those that combine geometry-based and image-based methods for detailed building reconstruction, published by authors such as Debevec et al (1996), El-Hakim et al (2002), or Remondino et al (2012) on one hand. And on the other, we have those that implement automatic procedures by computer vision techniques, both for image segmentation (detecting characteristics such as faces, edges and corners), as for automatic recognition of semantic classes of objects by means of 2D/3D matching.…”

Mesh-to-Bim: From Segmented Mesh Elements to Bim Model With Limited Parameters

“…The expected Dynamo-based HBIM modelling transfers the geometric structures to HBIM model via Revit Dynamo visual programming. The fundamental and manual work is to segment the raw point cloud into mesh solid geometry representing building components (i.e., walls, roofs, columns, slabs) (Remondino et al, 2012). Then, by visual programming in Dynamo environment, the solid geometry is transferred into Revit Family elements, and then the parametric relationships among building objects are also defined.…”
