Photogrammetry:relief technique to acquire and analyse photographical images. It identifies the position of the main points of a structure. Mainly used for the relief of regular structures.
GIS and VR webGIS: data processing system which allows to acquire, georeference, analyse, visualize and give back information coming from geographical data.
3D Modelling in Computer Graphic: process which develops a mathematical model of alive or inanimate 3D objects with a specialised software. It allows to apply graphic details to every single object providing a bigger reliability of the reproduction.
Computer Vision: photogrammetric technique which automatically uses sequences of partially overlapped digital images by creating not only geometrical 3D models but also realistic models with textures which reproduce the real aspect of the surfaces. Mainly used to reproduce the behaviours of some characters starting from the statue models.
Scanner Laser: an instrument which allows to acquire spatial data; the output is a 3D cloud of points. It's the non-intrusive technique mainly used within the project to analyse, monitor and survey buildings and structures at the highest level of detail.

Different relief technologies have been employed according to different requirements:the whole data have been inserted within a GIS project which keeps the variety and accuracy of the acquired spatial data.
Total Station: a high-precision relief instrument. It deals with all the elements similar to geometrical shapes, but it doesn't provide georeferentiated data. It has been used for the relief of architectonical structures and roads.
DGPS: system which exploits and improves the potentiality of traditional GPS system quickly generating high-precised data. Mainly used for wide morphological reliefs.
Photomodeling: relief technique which catches many photographs from different positions all-around the object to reconstruct 3D models of it through a series of 2D images. Mainly used for the relief of statues, small objects and buildings. |
