Heritage and technology: novel approaches to 3D documentation and communication of architectural heritage

Risultato della ricerca: Other

Abstract

In the past few years we have seen a drastic increasing of image-based modeling (IBM) techniques to gethigh quality reality-based 3D models. The low costs of these techniques as well as their attractive visualquality have lead many researchers and professionals to invest their energies and resources in several tests.The use of IMB in the field of cultural heritage is mostly exploited in applications such as documentation,digital restoration, visualization, inspection, planning, AR/VR, conservation and design.One of the strengthen of multi-view stereo techniques is the possibility to capture millions of points in a veryshort time and to get a 3D textured polygonal model that can be easily used for visualizing andcommunicating digital assets.Currently, we can distinguish between desktop and web based packages. If the first one needs a highperformance computer for data processing, the second one use the power of cloud computing to carry out asemi-automatic data processing instead of considerably slowing-down the computer. The aim of this study isto compare two of the most known IBM packages (Agisoft Photoscan and Autodesk Recap) in applicationsdealing with architectural heritage.The comparison among the chosen packages are typical user-oriented parameters such as: visualcompleteness/detail of the 3D model; ratio between images resolution/number of images/time processing;number of used/discharged images (useful to optimize the images network); metric accuracy; learningcurve/usability.
