摘要：Documentation of Cultural Heritage is a challenging task that is benefited from the new trends in digital acquisition systems. Graphical documentation is not a matter of providing right plans or drawings but also the cleverness to keep and transfer knowledge through them. Digital imaging sensors have contributed to spread the application of digital close range photogrammetry especially in monuments and sites, mainly because of costs reductions in hardware and software, on the one hand, and resolution and flexibility of either small or medium format cameras, on the other. The analysis of some damages or sources of alterations is not always fulfilled with visible imagery. Furthermore, the capability to determine alterations or damages through non visible sensors is very much appreciated by structural analysts or architects when they have to afford challenging situations in restoration works. Examples of such situations are moisture infiltrations, heat losses and last but not least rendered brickwork structures. This paper shows a documentation process that makes use of both visible and thermal IR imagery to analyse and map alterations on a masonry brickwork building. For that purpose, outer as well as inner shots were acquired and processed in order to plot on top of the metric imagery structural information and alterations. Additionally, analyses carried out with this unconventional approach are displayed and compared with ground truth data compiled by restoration experts
