    Abstract

    This study is framed within the field of survey of buildings belonging to the Cultural Heritage and Architectural . In particular it is classifiable within the technical investigation of the indirect type ( without contact with the object under investigation ) and nondestructive test ( without demolition, partial removals and / or micro - sampling ). Its aim is to identify, describe, test and verify a technique to carry out a survey of photographic type and integrate it with additional data derived from the acquired thermal imager with mid-level. It must be able to perform, for both the thermal image and for that camera, the correction of errors due to different optical (calibration) and in order to provide geometrically correct the overlapping of the images thus extracted. It is to have information concerning materials present beneath the plaster or finishes (such as frescoes) can not be eliminated, in order to understand the technical and construction characteristics, geometry and additional analysis of the degradation of the substrate hidden. It is often useful, then, to avoid errors in the process of restructuring, recovery or rehabilitation, you can make a correct geometric survey, referenced to adjacent architectural elements , and be able to report on the virtual model, to be developed subsequently and enrich the historical data, etc. degradation. The technique identified, from the calibration phase to that of relief and return graphics, allows to obtain useful data to additional relief techniques normally in use, especially if not integrated. The reliability of the data obtained was compared with the substrate as following the removal (in this case possible) of the plaster. Some detectable elements are defined, the conditions that allow us to obtain additional data, the thickness through which it is possible to "read" the heat elements, the " correctness " of the given geometric indirect, with respect to the detected directly.
