Historic centres’ surfaces. Integrated procedures for survey, diagnosis and conservation

The accurate use of integrated diagnostic procedures can be an effective tool in the study and analysis of historic architectural surfaces aimed at conservation, monitoring and restoration. Such integrated procedures could be very effective to define guide-lines useful at the future conservative interventions for the preservation of historical centres. By integrating historical documentation, 3D survey, macroscopic analyses and colorimetric characterization, it is possible to collect and merge historical, metric and conservative data. The paper will present some experimentation and results achieved by an integrated process where the reflectance data acquired by means of the 3D laser scanner becomes an effective diagnostic tool.
