Forma, dado e matéria : a incorporação de técnicas de fotogrametria e fabricação digital a estratégias de documentação patrimonial e restauro

Abstract

The current documentation paradigm among Brazilian institutions that carry out the process of safeguarding built cultural heritage today is still based, for the most part, on the construction of a database composed of technical illustrations generated from manual inferences in the field and digital models. generated from these illustrations. However, due to leaps in computing power and the democratization of technology, there is increasing accessibility to newer technologies, which are proving effective in producing more detailed and accurate digital records. Once the model-record is no longer based on two-dimensional abstractions of the building and is generated from a process of three-dimensional reconstruction of the built object, a more reliable record of the built heritage can be obtained. This record makes possible, as by-products, advantageous potential for restoration, education, and heritage dissemination processes, which make much use of detailed and accurate records. This work is committed to the elaboration of a representation device for elements of high geometric complexity present in the built cultural heritage, elaborated from digital models generated from automated photogrammetric reconstruction through Dense Stereo Matching (DSM), with a view to greater accuracy in recording useful information for restoration processes, allowing information transposition workflows that range from model data acquisition to its rematerialization, through an organized series of inference, modeling and fabrication processes.
