3D scanning applied to archeological objects or artifacts allows the shapes and their texture to be stored in a digital format, speeding up the process of representation, identification, and cataloging. The development of techniques such as digital photogrammetry and the availability of structured-light scanning equipment play an essential role in the capture of objects and works of art. One of them is research, as it contributes to the knowledge of movable and immovable assets. There are several strategic lines in Cultural Heritage (CH) dealing with the preservation, conservation, restoration, and maintenance of the built environment. Photogrammetry achieved an accuracy of 0.70 mm versus the Artec Spider and 0.57 mm against the Revopoint POP 3D scanner. Although the results of the 3D geometry may vary in a morphometric analysis depending on the device records, the results demonstrate similar accuracies in that submillimeter range. The work evaluates the accuracy of the devices through algorithms and the study of point density at the submillimeter scale. In addition, the precision of the 3D model is studied through a vector analysis in a BIM environment, an unprecedented analysis until now. Data capture accuracy is evaluated through a mathematical algorithm and point set segmentation to verify the spatial resolution.

For this, the precision of two structured-light scanners is compared with that of the photogrammetric technique based on short-range image capture: a high-cost Artec Spider 3D scanner, and the low-cost Revopoint POP 3D scanner. On this basis, this research addresses a small artifact with geometric singularities that is representative of small museum objects. Nowadays, with the development of structured-light data capture technologies, the geometry of objects can be recorded in high-resolution 3D datasets at a very low cost. Low-cost 3D sensors, particularly structured-light scanners, have evolved towards multiple uses in the entertainment market but also as data acquisition and processing techniques for research purposes.

Digital copies of the objects into Building Information Models (BIM) add cultural interest to every artistic work. Reverse engineering and the creation of digital twins are advantageous for documenting, cataloging, and maintenance control tracking in the cultural heritage field.
