Smart architectural models. Spatial projection based augmented mock-up

This paper illustrates some representative experimentation by means the use of digital video projections on architectural mock-up models, to enhance and promote architectonic cultural heritage of Ascoli Piceno, in Italy. Architectural video projection stylistic patterns may vary according to design process. Visual restoration, narration and architectural caprice represent different way to exhibit hidden aspect of cultural heritage, and they have been investigated in this paper. More specifically, this article will outline a scientific-technological framework regarding tools and procedural protocols to set up spatial projection based augmented reality applications. We describe several ways to augment architectural trivial and non-trivial models, on various scales and for different purposes. These ways involve digital video projectors and architectural scaled models to create light exhibit to enjoy without the use of mobile or through screen devices. Therefore, all various case studies presented in this paper, solve, with distinct and appropriate tests, different spatial conditions and projective geometry issues resulting from different positions and orientations of the projectors enlightening and augmenting mock-up models, through 2D and 3D ad hoc traced masks based on architectural surveys.
