Risultati ottenuti nell’ambito della sessione "benchmark" - uso di immagini UAV per la ricostruzione 3D: esperienze condivise tra utenti (61° convegno nazionale SIFET, Lecce 8-10 giugno 2016)

This paper summarize the achievements of an experimental meeting session held within the 61th SIFET national meeting (Lecce, Italy, 6-10 June 2016). The session named “benchmark” introduced results achieved by users in the processing of a shared dataset, composed of images acquired from unmanned aerial vehicle (UAV), to reconstruct the three-dimensional properties of cultural heritage. Data, results provided by authors and validation strategies of outcomes from the photogrammetric processing of UAV images highlighted different level of spatial accuracy by the products. Despite the good level of automation introduced by the structure from motion approach to data processing, the users detected differences at cm-level in the accuracy of results after the use of available software.
