The survey of St. Barbara’s cave church in Matera represents a moment of theoretical-operational reflection on the role of 3D models within the graphic-analytical process of knowledge implemented by the surveyor to document and analyze an architecture carved into the rock. In the survey, the laser scanner ToF and digital photogrammetry were integrated to take full advantage of the potential and peculiarities of the techniques used. In this way, it was possible to calibrate the level of detail of the 3D polygonal models, to transcribe both the general and detailed structures (frescoes, signs engraved on the surfaces, traces of rock processing, etc.), through canonical elaborations and typical figurations of the techniques employed.

Abstract
The survey of St. Barbara’s cave church in Matera represents a moment of theoretical-operational reflection on the role of 3D models within the graphic-analytical process of knowledge implemented by the surveyor to document and analyze an architecture carved into the rock. In the survey, the laser scanner ToF and digital photogrammetry were integrated to take full advantage of the potential and peculiarities of the techniques used. In this way, it was possible to calibrate the level of detail of the 3D polygonal models, to transcribe both the general and detailed structures (frescoes, signs engraved on the surfaces, traces of rock processing, etc.), through canonical elaborations and typical figurations of the techniques employed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
