3D RECONSTRUCTION-REVERSE ENGINEERING- DIGITAL FABRICATION OF THE EGYPTIAN PALERMO STONE USING BY SMARTPHONE AND LIGHT STRUCTURED SCANNER

2018

Abstract. This paper presents a pipeline that has been developed to acquire a shape with particular features both under the geometric and radiometric aspects. In fact, the challenge was to build a 3D model of the black Stone of Palermo, where the oldest Egyptian history was printed with the use of hieroglyphs. The dark colour of the material and the superficiality of the hieroglyphs' groove have made the acquisition process very complex to the point of having to experiment with a pipeline that allows the structured light scanner not to lose the homologous points in the 3D alignment phase. For the texture reconstruction we used a last generation smartphone.

A "laboratory" open air in the urban landscape of Palermo

2012

The study intends to make new contributions to knowledge of a interesting "laboratory" in the open air in the urban landscape of Palermo, a cultural and scientific heritage in which architecture, art and decoration coexist in an experiment of collective synergies. The Botanical Garden C enter, with its ten acres of land appears, still, a fervent creative process between artifice and nature, the expression of a specific historical and cultural climate in which expectations converged of a intellectual, scientific and institutional fervor. The academic institution, founded in 1789 with the intention of cultivating useful plants to the arts, crafts and medicine, contributed to the spread of tro…

Rappresentazioni tattili

2020

Sebbene molto spesso le persone con disabilità debbano accontentarsi di vivere parzialmente alcune esperienze, da diversi anni è aumentata l’attenzione dei siti museali verso la realizzazione di progetti e percorsi dedicati che consentano una fruizione tattile di opere e manufatti ai disabili visivi. Il contributo presenta due casi studio, che utilizzano modelli 3D per installazioni tattili. In presenza di deficit visivo, è importante rafforzare le facoltà percettive connettendo il tatto con i sensi residui e fornendo stimoli cognitivi diversi e paralleli. L’approccio multisensoriale, tattile e uditivo, realizzato grazie alla commistione tra modelli 3D e componenti elettroniche, favorisce l…
