In this article we develop a case study in order to obtain orthophotos to a wall surface of “Villa di Giulia Felice” in Pompeii. Given the length of the section and a very small distances to the object, it was necessary to test the use of an action camera: a “GoPro Hero 3 Black”. The distorting effects are the factors that characterize this type of camera and they are caused by the wide-angle lens mounted on it. For this reason, the “GoPro Hero 3 Black” is not particularly suitable for photogrammetric purposes. The photos were processed in different software and the 3D models obtained were compared in terms of geometric and radiometric information.

Abstract
In this article we develop a case study in order to obtain orthophotos to a wall surface of “Villa di Giulia Felice” in Pompeii. Given the length of the section and a very small distances to the object, it was necessary to test the use of an action camera: a “GoPro Hero 3 Black”. The distorting effects are the factors that characterize this type of camera and they are caused by the wide-angle lens mounted on it. For this reason, the “GoPro Hero 3 Black” is not particularly suitable for photogrammetric purposes. The photos were processed in different software and the 3D models obtained were compared in terms of geometric and radiometric information.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
