Overview

Cultural heritage digitization and 3D modelling processes are primarily based on laser scanning and digital photogrammetry techniques to produce complete, detailed, and photorealistic three-dimensional surveys: geometric and chromatic elements, as well as evidence of materials, work techniques, state of preservation, and so on, are all documented using digitization processes.

The study delves into the topic of 3D documentation for conservation purposes, examining how geomatics plays a role at various stages of the restorative process and providing a description of the different applications of 3D models for the preservation and improvement of cultural heritage. The paper describes a project to digitise earthenware archaeological relics for objectives of 3D documentation, restoration work support, and digital and physical reconstruction and integration. The desire to create an exhibition space proposes new ways to use 3D data that was initially collected for documentation and scientific objectives.

The availability of a complete, detailed, and photo-realistic 3D model of the objects of importance in the study of Cultural Heritage allows for the depiction of all characteristics relating to geometry, colours, and materials, as well as work processes and deterioration state. It also provides a variety of options for documentation, analysis, and research. This study recounts the experience of different private organizations in 3D digitising two significant monuments using a combination of 3D image-based and range-based methodologies.
