Tecniche laser scanner per il rilievo dei beni culturali

Laser scanner technology permits a rapid elaboration of digital models of surfaces and complex geometries which would be impossible to survey with traditional topographic instruments. It therefore represents the proper technology for surveying archaeological sites and objects of Cultural Heritage. In this paper the characteristics of different commercial instruments are described and their different resolutions in the acquisition of the coordinates and in measuring reflection. The presentation of some practical examples now gives us the opportunity to describe the operative process of 3D restitution from planning and performing the survey up to the development of specific procedures for the elaboration of data
