Moreover, the first method (automatic three images processing (ATIP)) proposes some easy procedures to solve typical non-linear problems of analytical photogrammetry. In particular, once validated the technique of orientation of two images (two-step procedure based on two phases: relative orientation and absolute orientation, both characterized by non-linear functions), we propose a procedure for the automatic orientation of three images (the introduction of a third image allows avoiding human decision to find the final solution). The second method (Computer Vision Raspberry Pi—CVR) refers to the use of the “prompt” technique of computer vision (structure from motion) using five appropriately synchronized cameras to acquire simultaneously the various frames, thanks to the use of an acquisition system based on the use of Raspberry Pi. The experimentation was conducted both in the laboratory (on a model that allows to study a typical phenomenon of the Alpine Valtellina region, in the North of Italy) that directly at sea (on a portion of marine surface located in Reggio Calabria near the seafront). The results obtained show a substantial comparability of the results both between the two methods and with the actual data measured at sea with dedicated instrumentation.

[Termes IGN] semis de pointsRésumé : (Auteur) For years, the Laboratory of Geomatics of the Mediterranean University of Reggio Calabria has undertaken an interdisciplinary project for the recovery and dissemination of information regarding the cultural-artistic and archeological heritage of the metropolitan area. The combined use of geomatics technologies (laser scanners, GPS positioning, digital photogrammetry, remote sensing, GPR) allows on the one hand to investigate objects and artifacts, providing metric, form, and location information; and on the other, to catalog information and make it accessible to the community. Indeed, the digitalization and reconstruction tools of 3D models can be the answer to the limits related to communicability in the archeological sector. Precision, detail, and very accurate photo-realistic reconstructions are particularly useful for virtual and augmented reality applications, integrating them in the devices used on a daily basis. The present note concerns, therefore, the acquisition of information using the point cloud from UAVs and laser scanners, the subsequent 3D modeling, and their representation in an augmented reality (AR) environment using mobile platforms. The application was tested on the church of Sant’Antonio Abate, located in the North of Reggio Calabria, which according to studies is the only evidence of medieval architecture in the territory of Reggio Calabria.
