Modern Tools of Geomatics as an Indispensable Support to the Public Administration for the Protection, Restoration, Conservation and Dissemination of Cultural Heritage

Abstract

AbstractThis research demonstrates the utility of some modern Geomatics tools (UAV, aerial photogrammetry, 3D models, Augmented and Virtual Reality, GIS) as an indispensable support to the public administration for the protection, restoration, conservation and dissemination of cultural heritage. The solution proposed by us is not as complete as [3], however it is faster, cheaper and more easily repeatable over time. Specifically, for the protection, restoration and conservation of the artifact detected, in order to obtain a 3D model (with geolocalized information and with precision of detail of a geometric-material survey), we initially created an aerial photogrammetric survey using of UAVs; subsequently we used the images acquired for the creation of a 3D model through the SFM, using the canonical method described in the manuals, continuing we made a comparison of the model previously obtained with a second 3D model (made using some tricks for noise reduction). The repetition of the photographic survey at fixed intervals, possibly to be included in the maintenance program, can allow a comparison over time of the evolution of deterioration and damage, and therefore establish a ranking of intervention priorities. Finally, for the dissemination, knowledge and enhancement of the artifact detected, we have created an AR/VR app and a GIS system.KeywordsUAVAerophotogrammetry3D modelAugmented realityVirtual realityGIS
