Résumé en anglais
The present essay is a result of a wider research we are conducting at the Laboratory of Architectural Photogrammetry and Survey of Catania directed by professor Luigi Andreozzi. The research concerns the experimentation on the scanner laser methodology applied to the study, the analysis and the documentation of the architectural heritage.The use of this new technology needs a critical approach in data acquisition and processing for a possible intervention aimed to study, document and represent the intrinsic characteristics of architectonic monuments. This is done to evaluate both the capacities enclosed by this methodology (high density cloud of points which describes exhaustively the morphology of spaces and objects of various
shape and geometry, in situ surveying times' reduction, consciousness of instruments' accuracy, surveying procedures' real time checking ) and the integration of obtained results with the other surveying methods to be useful in the dialogue between informationusers and information providers.
The case here presented concerns the study of the vaulted system which covers the so-called Small Refectory of the Benedictine’s monastery in Catania, designed in 1739 by a clever architect, G. B. Vaccarini. Because of its peculiar shape, for quite a time this room have been the centre of scholar diatribes in order to find out the geometrical genesis of its planimetric outline and arched ceiling.Research work has been conducted starting from the raw data which outcome from each single scan and applying different sofwares to elaborate the cloud of points in order to recognize studied surfaces geometrical origin, to build possibile virtual models able to document and express the geometrical-morphological-materical essence of the vaulted room analyzed.
