Metric surveys have a key role in managing Cultural Heritage. They are needed for a wide range of activities like documentation, study, restoration, and valorization. The importance of the 3D description of objects is widely accepted considering costs/benefits ratio and the opportunities it offers. In recent years, laser scanning and digital photogrammetry offered new perspectives, widening the options in 3D CH recording. Scientific research tends to see their integration as the best approach to CH description. 3D surveys are offering extra opportunities respect to the traditional production of metric supports as 3D models are the ideal base for true 3D information systems and open the way to immersive virtual reality environments. Digital technologies provide new ways to collaborate, record excavations, and restore artifacts in such a way, they are transforming the way CH practitioners work. This chapter attempts to review the methods for 3D digitization that are today available and discuss the possible use of 3D models beyond the pure extraction of reliable and accurate measurements. |
