“…Aicardi et al [73] worked with various software to establish the accuracy between GCP data and orthophotographs. A similar work by Peña-Villasenín et al [74] determined the accuracy of the camera arrangement on various façades. Sanz-Ablanedo et al [10] correlated the Root-Mean-Square-Error (RMSE) with the GCPs for UAV.…”

Validation of Close-Range Photogrammetry for Architectural and Archaeological Heritage: Analysis of Point Density and 3D Mesh Geometry

et al. 2020

The 3D digitization and Building Information Modeling (BIM), which is based on parametric objects, have considerably advanced by developing massive data capture techniques. Thus, reverse engineering currently plays a major role as these technologies capture accurately and efficiently the geometry, color and textures of complex architectural, archaeological and cultural heritage. This paper aims to validate close-range Structure from Motion (SfM) for heritage by analyzing the point density and the 3D mesh geometry in comparison with Terrestrial Laser Scanning (TLS). The accuracy of the results and the geometry mainly depends on the processing performed on the point set. Therefore, these two variables are significant in the 3D reconstruction of heritage buildings. This paper focuses on a 15th century case study in Seville (Spain): the main façade of Casa de Pilatos. Ten SfM surveys were carried out varying the capture method (simple and stereoscopic) and the number of shots, distances, orientation and procedure. A mathematical analysis is proposed to verify the point spatial resolution and the accuracy of the 3D model geometry by section profiles in SfM data. SfM achieved acceptable accuracy levels to generate 3D meshes despite disordered shots and the number of images. Hence, stereoscopic photography using new instruments improved the results of close-range photogrammetry while reducing the required number of photographs.

“…The spatial resolution of point clouds has been scarcely determined. Peña-Villasenín et al [74] analyzed the point density per square meter in four case studies of photogrammetry. The point density was therefore evaluated according to the surface area.…”

“…For example, Moyano et al (2020) evaluated the accuracy of SfM point clouds against TLS for large architectural spaces with a symmetrical configuration, with the main courtyard of Casa de Pilatos in Seville, Spain, as a case study [23]. Four representative cases of different urban facades' typologies were selected in the historic center of Santiago de Compostela by Peña-Villasenín et al [24], focusing on the photoshoot arrangement.…”

A Scan-to-BIM Methodology Applied to Stone Pavements in Archaeological Sites

et al. 2021

View full text Add to dashboard Cite

The transition from Building Information Modelling (BIM) to Heritage Building Information Modelling (H-BIM) is intended to pursue an adequate knowledge of the artefact that is to be preserved, progressively replacing the traditional methods of restoration and structural reinforcement projects with new tools for the management of both existing information and new interventions. The aim of the paper is to show the application of the H-BIM method to a stone pavement road located in the Archaeological Site of Pompeii. In detail, starting from a laser scanner-based survey, juxtaposed with coordinated points georeferenced through a total station, point clouds were handled by means of several BIM-based tools to perform the road design process, starting from the digital elevation model (DEM) and proceeding to the corridor representation. Subsequently, a visual programming application based on Python language was adopted to update the corridor information by means of the object property set. As preliminary results, a tool, complete with graphical and non-graphical information, is proposed to be used in conservation, maintenance and restoration projects.

“…Many of these techniques are still commonly used even though continuous progress in computing capabilities and the degree of automation of the different algorithms involved in a 3D modelling process now allow for greater methodological flexibility. Current versions of most commonly used photogrammetric tools perform the orientation of images with different focal points in sufficiently large groups of images; in other words, in the case of focal changes, sufficient images must be available in the image group for proper camera orientation with each of the focal lenses used (Peña‐Villasenín, Gil‐Docampo, & Ortiz‐Sanz, ). While these aspects affect the quality of 3D models (Al‐kheder, Al‐shawabkeh, & Haala, ; Remondino & El‐Hakim, ; Waldhäusl et al, ), their influence is largely irrelevant in rock art registration due to the small size of many petroglyphs.…”

In recent years, three-dimensional (3D) modelling with photogrammetry and enhancement methods from computer graphics communities have been used with excellent results for studies of rock art engravings. However, despite their abundance, most Atlantic rock art elements in the Iberian Peninsula have not yet been geometrically documented in 3D. The aims of this study include deepening the application of imaged-based modelling, digital 3D model post-processing, and diffusion tools in determining an accessible and straightforward workflow that is accessible for amateur and professional rock art researchers. The proposed workflow makes possible the prospection, documentation, enhancement, and diffusion of this heritage phenomenon in a massive collaborative manner. Thus, a representative sample of Atlantic rock art was documented using an affordable and time-optimized methodology for image-based modelling with free software at all stages of the process. This methodology improves the promotion of documentation of heritage through professional and social collaboration. The diffusion can be performed from two-dimensional (2D) vectorizations from the rendering of MeshLab Radiance Scaling enhancement and automatic vectorizers or from the direct publication of enhanced 3D models, which are currently possible with platforms such as Sketchfab.
