Nowadays, unfortunately the decay’s state of a big number of Cultural Heritage artifacts, requires a restauration work to be kept in a good state maintaining their integrity and duration. However, minor preventive intervention is necessary to reduce the resources to be allocated to more economically demanding restauration activities, allowing their accessibility to the public. A non-destructive analysis plays a fundamental role to understand e identify a possible degradation state. Thermography analyses are central to determine the thermo-absorbing capacities of the constituent elements ‘artifact and the possible material’s changes or lesions’ presence, otherwise identifiable to the naked eye. This paper illustrates a methodology to create a 3D model by combining, through soft computing techniques and digital photogrammetry, the point clouds obtained from the processing of thermographic images and RGB; in this way it is possible to obtain a geometrically accurate model that also reports the thermographic values. This methodology is applied on concrete sample (in which the presence of cracks was already known). The goal is to experiment with a process that lets the use of thermal sensors alongside digital cameras in the photogrammetric field in order to obtain a product that allows to extrapolate the geometric and thermal information of the object of study.
