What is Laser Scanner Survey

Chapter 14
Handbook of Research on Emerging Digital Tools for Architectural Surveying, Modeling, and Representation
The survey with 3D Laser Scanner technology that allows to remotely detect the morphology of an architectural structure, through a beam of light (laser) that slides on the surface to be surveyed. Through a greater or lesser densification of the scan mesh it is possible to make both general and detailed observations in correspondence with particularly complex or significant architectural elements. The laser beam returns for each real point of the “stretched” mesh of the object a virtual point with the 3 spatial coordinates. The totality of all these points constitutes a cloud of points, or the faithful “solid image” of a monument. These points, in addition to describing the object spatially, are able to give information about the reflectance of the object and the RGB (image) of the surface.

Abstract
Aim of this paper is focusing on experiences that combine an analysis on territorial, urban and architectural scale with computerized techniques of representation. These experiments (conducted in PRIN 2006 and 2008 national researches) had as focus the use and development of information systems to test their efficiency as an aid to analysis and survey of the Cultural Heritage, specially Urban and Architectural Heritage. Particulary, the aim of this paper is focusing on experiences that combine an analysis on territorial, urban and architectural scale with computerized techniques of representation.
