Abstract
Abstract. The digital acquisition of Cultural Heritage is a complex process, highly depending on the nature of the object as well as the purpose of its detection. Even if there are different survey techniques and sensors that allow the generation of realistic 3D models, defined by a good metric quality and a detail consistent with the geometric characteristics of the object, an interesting goal could be to develop a unified treatment of the methodologies. The Chapel of the Holy Shroud, with its intricate articulation, becomes the benchmark to test an integrated protocol between a terrestrial laser scanner (TLS) and a wearable mobile laser system (WMLS) based on a SLAM approach. In order to quantify the accuracy and precision of the latter solution, several forms of comparison are proposed. For the case study the ZEB-REVO, produced and marketed by GeoSLAM, is tested. Computations of cloud-to-cloud (C2C) absolute distances, comparisons of slices and extractions of planar features are performed, using stationary laser scanner (Faro FocusS S350) as a reference. Finally, the obtained results are reported, allowing us to assert that the quality of the WMLS measurements is compatible with the data provided by the manufacturer, thus making the instrumentation suitable for certain specific applications.
Highlights
1.1 Sensor integration for Cultural Heritage documentationThe knowledge construction, as theorized by Aristotelian gnosis, finds its incipit in the sensorial perception of substance and materializes in an inductive process that, thanks to memory and experience, reaches the interpretation of non-substance, of the intelligible, producing a cultural enrichment
4.1.1 C2C absolute distance computation: this first analysis involves the extraction of the region occupied by the altar from the previously registered homologous models, with subsequent C2C comparison
The first three wearable mobile laser system (WMLS) paths are employed, each of them compared with the merged terrestrial laser scanner (TLS) cloud
Summary
The knowledge construction, as theorized by Aristotelian gnosis, finds its incipit in the sensorial perception of substance and materializes in an inductive process that, thanks to memory and experience, reaches the interpretation of non-substance, of the intelligible, producing a cultural enrichment From this point of view, being witness to an ancient creative action transcends the pure substance aesthetics. Principles already established by the numerous Charters for the Restoration that trace the real motivation of conservation and safeguarding of heritage in the social function carried out, establishing the right both to information, to be guaranteed through the prompt communication, and to enjoyment, to be assured in the most appropriate forms (Niglio, 2012) In this articulated panorama, the complex function performed by the digital survey can be framed. The second and more complex aspect concerns the overall quality of the model, a very delicate issue for those involved in threedimensional surveying for documentation, restoration, replication and conservation purposes (Beraldin, 2004)
