Heritage and technology: novel approaches to 3D documentation and communication of architectural heritage
In the past few years we have seen a drastic increasing of image-based modeling (IBM) techniques to get high quality reality-based 3D models. The low costs of these techniques as well as their attractive visual quality 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 very short time and to get a 3D textured polygonal model that can be eas…
Il Portico meridionale della Cattedrale di Palermo: sperimentazioni di rilievo attraverso l’utilizzo di tecniche Structure from Motion
Structure from Motion (SfM) techniques constitute a very fertile field of investigation within the research of the surveying sector and that of the representation of architecture. They allow us to reach higher levels of reliability and accuracy, both metric and graphical, extremely quickly and with lower costs than other methods, including the laser scanner. In this study, we report the results of some experiments carried out on the southern Portico entrance of the Cathedral of Palermo through the use of the SfM techniques later validated by comparison with the point cloud obtained from laser scanning.
