The documentation and 3D modelling of Cultural Heritage are now mainly based on digital techniques to produce complete, detailed and photorealistic three-dimensional surveys. The integration of various technologies and sen- sors is the best solution to obtain results with these characteristics. According to the reproduction scale, you need to change the characteristics of the instruments used during acquisition. Some objects can be reproduced in full scale, such as for example archaeological finds, sculptures, decorative ele- ments and so on... Generally, acquisitions are carried out with triangulation or pattern projection systems, which ha- ve a limited operating range and provide an accuracy of 0.1 mm.
