Abstract
Abstract. In recent years research works have shown that augmented reality tools can offer effective support for the dissemination of architectural heritage, when integrated into the information data extracted with surveying and representation tools and further data from other sources, e.g., history.The development and permanent updating of software platforms dedicated to augmented reality, i.e., Apple's ARKit and Google's ARCore, as well as the introduction of new features, offer today affordable support for the development of AR solutions.Some operational difficulties are due to the rapid and constant evolution of the technologies; the available solutions can be compared to prototypes and the development of user experience effective solutions appears still lacking. The main subject in the construction of AR solutions is still linked to the development of effective methods to properly set up the visualization of 3D models and their interaction with the real scene. The chosen case study for the test of persistent AR solution for the visualization of works of art is the ‘Tribuna’, i.e., a monumental and sculptural marble apparatus, that decorated the main apse of the Cathedral of Palermo.
Highlights
The paper reports the outputs of a research work that aims at testing the efficacy of the Augmented reality solutions for the onsite visualization of sculptural and architectural works that have been changed or are lost after modifications or destructions that interested the work itself or the building that hosted the work
The aim of the research is the definition of a modus operandi to create three-dimensional digital contents that uses surveying and modelling techniques, integrated to historic sources, to build virtual reconstructions and propose their visualization on site with AR solutions running on mobile devices
The research proposes an approach to the definition of AR applications based on time-persistent solutions, using the cloud storage system of anchors and the Area Target technology developed by Vuforia
Summary
The paper reports the outputs of a research work that aims at testing the efficacy of the Augmented reality solutions for the onsite visualization of sculptural and architectural works that have been changed or are lost after modifications or destructions that interested the work itself or the building that hosted the work. The proposed research work aims at testing two different AR solutions that are capable to provide AR multi-user, repeatable and time persistent experiences. The first tested solution uses the Persistent cloud Anchors technology of Google ARCore; the second one is based on the Area Targets solution available on the AR Vuforia platform. The paper reports the workflow that led to the construction of the two AR solutions and a comparison of their on-field performances
