A fotogrametria é uma técnica que utiliza a fotografia como ponto de partida, tendo várias
aplicações, como por exemplo, o levantamento topográfico de terrenos, edifícios e
monumentos.
Nesta dissertação foi aplicada a técnica ao levantamento de edifícios e monumentos, em
alternativa aos levantamentos tradicionais, onde todas as medições são obtidas manualmente.
Foram escolhidos uma fachada de um edifício e um monumento histórico da cidade de Viseu,
cujos levantamentos foram realizados utilizando recursos correntes e disponíveis no
Departamento de Engenharia Civil da Escola Superior de Tecnologia e Gestão de Viseu.
Utilizou-se, também, um programa informático desenvolvido especificamente para a
fotogrametria.
Os levantamentos realizados geraram modelos 3D em wireframe (estrutura de arame) e com
texturas. Após a retificação dos modelos, cotaram-se os desenhos, sendo possível efetuar
medições dos elementos constituintes da fachada do edifício e do monumento.
ABSTRACT: Photogrammetry is a technique that uses photography as a starting point, with various applications, such as surveying land, buildings and monuments. In this dissertation the technique was applied to survey buildings and monuments, as an alternative to traditional surveys where all measurements are obtained manually. It was chosen a building’s facade and a monument from the city of Viseu, which surveys were carried out by using available resources in the Department of Civil Engineering of the School of Technology and Management of Viseu. It was also used a software developed specifically for photogrammetry. The surveys generated 3D models in wireframe and textured. After rectifying the models, the drawings were dimensioned, allowing obtaining any measure.
