A 3D scanning device for architectural survey based on Time-Of-Flight technology

This work is intended to show the results of a few architectural and archaeological surveys realized by means of a 3D scanning device. based on TOF (Time-Of-Flight) technology. The instrument was set up by the Art Diagnostic Group of the National Institute for Applied Optics (INOA) and it is composed by a high precision scanning system equipped with a commercial low-cost distance-meter. This device was projected in order to provide the following characteristics: reliability, good accuracy and compatibility with other systems and it is devoted to applications in Cultural Heritage field.
