Contributos das tecnologias de digitalização tridimensional para o levantamento arquitetónico: o caso de estudo da Igreja Matriz de Torre de Moncorvo

Abstract

The present dissertation aims to constitute an academic contribution regarding the use of non-intrusive architectural survey methods, such as photogrammetry and 3D scanning by use of laser scanner, as fully viable documentary methodologies in the production of graphic documentation, to serve as support in practical situations of architectural survey for restoration and conservation purposes in built historical heritage. Therefore, the object of study to be examined here is the church of Nossa Senhora da Assunção of Torre de Moncorvo, located in the province of Trás-os-Montes, framed by Serra do Reboredo, which has been the subject of a safeguard and maintenance project by Direção Geral de Cultura do Norte. This project stems from a survey also developed in a professional context by the co-supervisor in which the author actively participated, through the use of aforementioned photogrammetry and 3D laser scanning methods, using a variety of equipment and computational processing, which resulted in orthographies that served as substrate for the elaboration of vector drawings, digital models and descriptive narratives about the church, on web visualization platforms. The collecting and processing of these data provided the production of the plans, sections and elevations presented in this work. Throughout the thesis, we discuss what the architectural survey consists of, how the methodologies listed here work, and a description of the object of study is carried out for a better contextualization of it with the proposed technical approach.
