The first part of the research aims to \nthe reconstruction of the original aspect of an incomplete sculpture, by\n using photogrammetry techniques based on standard resolution photos and\n free software in order to obtain a first model; then, we integrate this\n model with other 3D digital data (from other sculptures of the same \nperiod) or with 3D modelling based on historical sources and views from \nhistorians, aiming to achieve the original aspect of the sculpture. The \nsecond part of the research consists of the embedding of the obtained \nmodel in a custom application able to render in real-time the 3D \nreconstruction of the lion. Then, the rendering is overlaid to the video\n stream of the real scene and, as a result, a complete 3D digital model \nof the sculpture is achieved and could be visualized through a VR \nviewer. As a case study, we focus on a Roman stone sculpture of a male \nlion conserved in the Museo Estense of Modena (Italy), which lacks of \nits head and its four legs. The original aspect of the lion may be \nachieved by integrating the damaged sculpture with other photogrammetric\n reconstructions of lions sculptures of the same period and with 3D \nmodel based on historical sources. Finally, the lion is visualized \nthrough an augmented reality application which digitally overlays the \nreconstructed models on the original one.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>https:\/\/iopscience.iop.org\/article\/10.1088\/1757-899X\/364\/1\/012018 This paper proposes the integration of photogrammetric reconstruction, 3D modelling and augmented reality application in order to achieve the complete visualization of a stone sculpture even if highly damaged or fragmentary.
