Achievement of the “Benchmark” session - On the use of UAV images for 3D reconstruction: a joint experience among users” (held during the 61th SIFET meeting, Lecce, Italy, June 8-10, 2016)

Abstract

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.
