New approach for optimizing the interpretation and representation of the degree of historical-archaeological evidence in the virtual reconstructions

Virtual reconstruction is defined as the visual recovery of a building or object through the creation of a three-dimensional model of the asset to be reconstructed, in a historical context. To provide the degree of veracity to the virtual reconstructions performed in the scope of heritage, the so-called historical-archaeological evidence scale emerged. Some authors have already used this methodology to provide their reconstructions with the degree of evidence, although none of the current propositions of evidence scales have been standardised to date. Moreover, it is still important to disseminate such scales as much as possible, since it has been shown that neither experts in this field of knowledge nor common users know about this methodology. The aim of this study was to design and create a new proposition of historical-archaeological evidence scale based on the achromatism and implement it in the ‘Baker’s House’ at the archaeological site of Torreparedones (Baena, Córdoba, Spain). To carry out this investigation, it was essential to compare and analyse each proposition of historical-archaeological evidence scale. The qualitative and quantitative studies about the existing scale propositions also played a fundamental role in the realisation of this work. These results, in addition to the chromatic study, support the creation of a new proposition of historical-archaeological evidence scale, designed for any type of viewer. Each phase of the study met the quality standards established for this type of research.
