Micro-photogrammetry
Analytical technique description: The technique is totally non-invasive, is used to assess the state of conservation and monitoring of restoration projects in the field of Cultural Heritage.
Generated a three-dimensional model of the studied area, is possible to estimate the surface modification, and generate roughness profiles.
Moreover the 3D models, generated at different time, can be overlapping in order to study the surface modification.
Applications:
In-situ application on painted surfaces, fresco, stone and wood material, or 3D reconstruction of small artifacts.
Basics:
Micro-photogrammetric method, based on the principles of classical photogrammetry, allows to generate a measurable 3D model, of small portions of the surface, or artifacts of limited size, by overlapping three or more digital images, captured by a camera system.
The technique requires an adequate natural or artificial lighting.
Instrumental details:
ZScanMicro, MenciSoftware, Arezzo (Florence Unit).
