6. CONCLUSIONS 
Different 3D measurement techniques are currently available 
each one with peculiar characteristic in terms of accuracy, 
density of the measurement or acquisition time. On the other 
hand in the archaeological field we can find a lot of different 
structures, that are more suitable to be measured with a 
technique rather than another one. Although this is not 
completely an original idea, the approach that we tried to set up 
is a technique for mixing different technologies, with specific 
targets and rototranslations based on the quaternions method, in 
order to exploit the characteristics of each technology in the 
most suitable way according to the manufact to be surveyed. 
The final “multiscale” 3D model seems to demonstrates a 
possible way for handling the resulting survey. 
7. ACKNOWLEDGEMENTS 
The author wish to express their thanks for the availability of 
Simone Orlandini, by Nikon Italia, that actually performed the 
3D scan with the Rigel equipment.
