Close-range photogrammetry: a wall sample composed of jugs | Fotogrammetria a distanza ravvicinata: un campione di muro composto di anfore

The recursive action of the survey has made it possible to advance the most intimate understanding of the construction methods of the artistic ceramics factory, built between 1954 and 1955 in Vietri sul Mare. The article presents and discusses the results of photogrammetry carried out using the SfM technique. The various fractures in the main front of the south façade, some of them at the height of the operator, led to the graphic description of the clay amphorae used to build the infill wall instead of perforated bricks. The process followed used two reality-based methods to transform the meshes into topologically modifiable models: 1) abstraction and extraction of the meshes converted into polyhedra 2) free-form geometries. The paper illustrates the process followed to obtain 3D configurations suitable to be processed for finite element analysis (FEA). The results will be used to help make the models derived from different other techniques such as laser scanning, informative.
