Computer Aided Restoration Tools to Assist the Conservation of an Ancient Sculpture. The Colossal Statue of Zeus Enthroned

Abstract

ABSTRACT:The research focuses on the contribution of the integrated application of Computer Aided Restoration digital procedures as a means to guide the integration measure of an artifact, innovating and implementing the traditional investigation methods. The aim of the study was to provide effective geometrical-formal investigation tools in the frame of the conservation work of Zeus enthroned from Soluntum, conserved in the Archaeological Museum "A. Salinas" of Palermo. The paper describes the workflow of the 3D acquisition and graphical modeling with non-invasive digitalization and high information density techniques to assist the conservation of the legs of the throne, especially the integration of the missing part. Thanks to the technique of the digital fabrication it has been reconstruct the two missing parts following the theoretical criteria as: recognisability, compatibility and retractability. This innovative application of 3D digital technologies have showed as the integrated use of the new technology can be a useful tools for improving the conservation of a work of art.

Similarity Index Based Approach for Identifying Similar Grotto Statues to Support Virtual Restoration

“…Their algorithm efficiently searched for matching fragments using the scanned geometry. Other scholars virtually reconstructed the broken heritage objects by utilizing their own axes, generatrices, and other geometric features [3,5,34]. Fantini carried out human-machine interactive virtual restoration of damaged ancient skulls, damaged pottery figurines, and stone statues [6,34,35], where the symmetry was obvious.…”

According to the above studies, the symmetry axis can be used as evidence for cultural heritage restoration, but it may not be suitable for grotto statues.…”

High Quality Texture Mapping Process Aimed at the Optimization of 3d Structured Light Models

“…The structured light system works with a light source projecting a series of light patterns on the object to be scanned (blue LED). The reflected image is captured by cameras, and from the analysis of the distortion of the pattern, the position is evaluated on each point of the surface to be scanned (Di Paola, et al, 2017).…”

SfM Techniques Applied in Bad Lighting and Reflection Conditions: The Case of a Museum Artwork

“…The methodology adopted, requires skills in the fields of image acquisition and processing. [13][14]. However, it would be desirable to identify a repeatable methodological approach in these extreme conditions.…”
