Rilievo tridimensionale di reperti archeologici: tecniche a confronto

This contribution is intended to present the results of some comparative tests between different techniques for tridimensional digital documentation, applied to archaeological finds. Both open source and proprietary solutions have been analyzed, investigating pros and cons of their approach and considering the characteristics
of hardware and software components from an archaeological point of view.
Our attentions was especially focused on Computer Vision applications (mainly based on software) with a comparison of Microsoft’s product Photosynth with the GPL licensed Bundler. Another point of interest
(hardware side) has been the investigation on optic sensors, which took us to concentrate on the triangolation laserscan Next Engine (proprietary) and on the structured light Three Phase Scan (open source).
