Digital Graphic Survey of Funerary Architecture - The “Museum of Silence” of the General Cemetery of Valencia

Abstract

[ES] Currently, techniques for obtaining 3D models are booming due to the infinite applications of these models. Photogrammetry by SfM (Structure from Motion) is a whole new subject that is emerging in this field of modelling, as it is a technique that allows us to obtain high-resolution 3D models with a camera. This project will address the study of this new subject and its application in the development of 3D models, as well as the workflow with other capture techniques, such as laser scanning and its possible virtual applications. Currently, the most precise method to capture 3D information is the laser scanner, but it has weaknesses, which are precisely one of the strong points of SfM photogrammetry. A brief tour will be made of all the techniques that exist to give photorealism to a terrestrial laser scanner (TLS) scan, to then present the developed and proposed technique on a real example and, in this way, obtain conclusions. In the end, the solution is proposed to the Museum of Silence, where, with augmented reality, options are proposed to safeguard the Funerary Heritage from theft with the creation of virtual models, 3D reproductions of sculptures and other elements that are victims of vandalism.
