GIOVANNI CURIONI’S DIGITAL MUSEUM (1/2): COMPARATIVE SURVEY TECHNIQUES FOR THE DEFINITION OF A 3D DATA COLLECTION PROCEDURE WITH LOW-COST SYSTEMS

Abstract. The potential of Virtual Heritage, with particular attention to the field of knowledge dissemination, not only in the educational and scientific field, of museum collections, which are very often not accessible, have long been at the centre of the digitisation policies of major national and international institutions. Within this framework, the proposed research is part of a broader research, involving scientific figures from different disciplinary fields for the definition of a workflow for the 3D acquisition, digitisation and creation of a virtual model of miniatures of architectural artefacts kept at the Polytechnic of Turin. The paper describes part of the experimentation conducted for the creation of 3D surveys carried out using different tools, such as a portable LIDAR, Mantis F6, a low cost LIDAR, iPhone 13 Pro, and a digital camera, Nikon Z5, evaluating their performance not only from a metric point of view, but also from a methodological point of view and the subsequent sharing of models in accessible digital environments. The conducted study therefore initiates a process of memory digitisation in order to create a digital platform in which to insert, in an organised and digitised manner, models, data, historical morphological information, material, documentary, etc., in order to make interaction with the virtual reconstructions possible, promoting a new accessibility, all this to test, standardise and define a possible working protocol for massive low-cost 3D artefacts acquisition.
