Abstract

Numerous factors must be managed to ensure high quality and accuracy of sub-millimetre resolution models. In this regard, this study reports two examples of surveying objects of accentuated complexity: the precious ones of Constance. These are two emblematic cases selected to determine whether the recording systems chosen, a structured light scanner and a low-cost camera integrated into a USB microscope, could support the requirements of accurate and reliable three-dimensional reconstruction.<BR />The work conducted allowed us to experiment different technologies, highlighting their peculiarities but also the limits that each of them has in particularly complex conditions. Like often happens in the archaeological environment, the objects to be surveyed present unique as well as varied characteristics, which is why a single type of instrument is often not always able to completely render the final three-dimensional model. This underlines the complexity of the survey process and the difficulty in finding a single pipeline.
