In this paper a multisensor approach (topography, photogrammetry, laser scanning) was exploited to generate a close range model of a cultural heritage object in order to evaluate the accuracy of data in all steps of the model production, from the acquisition to the representation. A programmed data redundancy allowed to verify the accuracy of each technique as well as the presence of possible surveying errors. At the end, a comparison from data acquired by different tecniques was done in order to verify the accuracy of the laser model. We have explored the entire workflow to obtain a complete 3d model: range image registration, points decimation, triangulation, mesh editing, model texturing. The results are here presented.

Abstract

In this paper a multisensor approach (topography, photogrammetry, laser scanning) was exploited to generate a close range model of a cultural heritage object in order to evaluate the accuracy of data in all steps of the model production, from the acquisition to the representation. A programmed data redundancy allowed to verify the accuracy of each technique as well as the presence of possible surveying errors. At the end, a comparison from data acquired by different tecniques was done in order to verify the accuracy of the laser model. We have explored the entire workflow to obtain a complete 3d model: range image registration, points decimation, triangulation, mesh editing, model texturing. The results are here presented.
