Smart architectural models: Spatial projection-based augmented mock-up

This paper illustrates some representative experimentation through 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 the design process. Visual restoration, narration and architectural caprice represent different ways to exhibit the hidden aspect of cultural heritage, and they are 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. This paper describes several ways to augment architectural trivial and non-trivial models, on various scales and for different purposes, including digital video projectors and architectural scaled models. The intent is to create light exhibit to be enjoyed without the use of mobile or through screen devices. Therefore, all the case studies presented in this paper, solve, with distinct and appropriate tests, different spatial conditions and projective geometry issues resulting from diverse positions and orientations of the projectors enhancing and augmenting mock-up models, through 2D and 3D ad hoc traced masks based on architectural surveys.
