Photorealistic 3D Digital Reconstruction of a Clay Pitcher

Abstract

The availability of 3D scanning devices allows performing the process of digitisation of a growing number of diverse museum artefacts. After the properly conducted processing of the acquired point cloud, the authors obtained a photorealistic digital copy that can be presented in many ways. With regard to the objects from archaeological excavations, the vast majority are the artefacts that are more or less damaged or only partially preserved. Their state of preservation, specialised archaeological knowledge and the use of appropriate 3D computer technologies allow their complete digital reconstruction. The present work concerns the development of alternative methods and algorithms of conduct, the selection of programs and tools to recreate the surface of the outer and inner side and the bottom of a 12th century pitcher from the Afrasiab excavations in Uzbekistan.

Copyright Protection of 3D Digitized Artistic Sculptures by Adding Unique Local Inconspicuous Errors by Sculptors

“…In recent years, 3D scanning has become a widespread technique for collecting 3D images of cultural heritage artifacts, in the areas of small historic objects [40][41][42], sculptures [43][44][45][46], rooms [47,48], or large buildings and entire architectural sites [49][50][51][52]. Structured lighting technology is suitable for the digitization of cultural heritage objects because it is a contactless method for 3D digitization [53].…”

Comparative Analysis of Digital Models of Objects of Cultural Heritage Obtained by the “3D SLS” and “SfM” Methods

“…In the last two decades, the acquisition of three-dimensional data by laser scanning [6], using structured light [7] or SfM [2,8] has become one of the standard methods of documenting cultural heritage. It makes it possible to analyse the shape, geometry historic artefacts in a safe way [9].…”

“…So attention should be paid to getting much more photos of the subject (from 80 to 140). (7) The time of the SfM method when applied to small objects can be reduced (more than 4 times) with careful photographing, paying attention that the object is well-framed, without unnecessary background of the surroundings. (8) The classic SfM method does not provide for placing markers next to the photographed object, so the obtained digital 3D models do not have information about their dimensions.…”

Virtual scientific expedition for 3D scanning of museum artifacts in the COVID-19 period – The methodology and case study

“…With these, it was possible to make scans of nearly 100 museum artifacts and 12 large architectural objects. Gathered data was used for the purpose of research methodologies verification and preparation of new articles ( Montusiewicz et al, 2018 , 2019 ; Miłosz et al, 2020a , 2020b ; Żyła et al, 2020 ). During the scientific seminars, both the joint achievements and opportunities for further cooperation were presented.…”
