Advanced video mapping techniques - Spatial Augmented Reality applied to cultural heritage

This volume is intended to be an exhaustive guide for all those who, already masters the basic techniques of video mapping, want to deepen the subject and in particular want to focus attention on the Spatial Augmented Reality (SAR) applied to cultural heritage, whether artistic, archaeological or museological.

SAR offers in this sector great unexplored opportunities, especially if you think of its hybridization with traditional museographic systems or with more futuristic mixed reality systems; it is often configured as the best action to be interpreted to communicate the past as it frees the user from the brightness of other systems.

The text, starting from a quick overview of the current technologies that are laying the foundations for those of the future, addresses the advanced techniques of surface acquisition and then move on to the theme of modeling and MadMapper, currently the only software with specific functions for video mapping.

The last chapter is finally dedicated to the theme of augmented heritage and focuses attention on the use of multimedia procedures for the communication of cultural heritage with digital technologies both audio and video.
