Survey and modeling. From the process to a methodology

Documentation of architectural and archaeological heritage must be a multidisciplinary approach that enables analysis and interpretation from many fields of expertise. Nowadays, the representation of the architectural/archaeological survey represents a monumental change in capabilities thanks to the acquisition and alignment of massive survey data describing the geometry, appearance and context of the target environments. The construction of models is the point of departure for essential activities – from cataloguing to preservation, from design to restoration and valorization – linked to the knowledge of Cultural Heritage. The presented research focuses on the control over data quality from massive 3D acquisition, in terms of metric accuracy, by comparing 3D image-based acquisition methods with consolidated methods, in order to present the enormous potentialities inherent in models obtained through 3D surveys.
