Abstract(s)
Com o tempo, as estruturas de construções civis ficam sujeitas a muitos fatores, sejam eles externos ou até mesmo inerentes às próprias estruturas, que influenciam significativamente em suas condições. Para que se possa mantê-las por muito anos, faz-se necessário investigar de forma detalhada seu estado de conservação e para isso, usualmente recorre-se a inspeções visuais que permitem avaliar seu estado de conservação e com isso adotar procedimentos corretivos necessários. Entretanto, alguns tipos de estruturas tais como torres de telecomunicações, pontes, plataformas de petróleo offshore, torres de transmissão de energia eólica, e outras, apresentam dificuldade no acesso para que o inspetor possa realizar suas tarefas. Através deste trabalho, avalia-se a contribuição da utilização de Veículo Aéreo Não Tripulado em atividades de inspeção visual. Por meio dele, é apresentado de forma teórica o funcionamento de uma inspeção visual tradicional, em contraste com a pesquisa prática de inspeção da Torre do Monte da Virgem, em Portugal, com a utilização de Veículo Aéreo Não Tripulado (VANT) e posterior processamento digital de imagens através dos softwares MATLAB e PIX4Dmapper junto ao preenchimento de fichas de inspeção, para então avaliar o estado de conservação. A metodologia apresentou resultados satisfatórios, sendo a utilização de Veículo Aéreo Não Tripulado de grande valia, mas a metodologia também apresenta algumas limitações.
Along the time, civil construction structures are subject to many external factors or even factor inherent to the structures themselves, which significantly influence their conditions. In order to keep them for many years, it is necessary to investigate their conservation status in detail and, therefore it is used to do visual inspections that allow evaluating their state of conservation and finally planning necessary corrective actions. However, some types of structures such as telecommunications towers, bridges, offshore oil platforms, wind power transmission towers, and others, are difficult to access or present risks for inspector’s task performance. This paper aims at the contribution of Unmanned Aerial Vehicle (UAV) usage in visual inspection activities. Through it, it is presented in a theoretical way the methodology of a traditional visual inspection in contrast to the practical research of inspection of Monte da Virgem Tower, in Portugal, with the use of Unmanned Aerial Vehicle Matrice 600 Pro, and then processing the achieved images in the software MATLAB and PIX4Dmapper. In order to evaluate the state of conservation, after digital image processing, inspection forms were filled. The methodology presented satisfactory results, being the use of Unmanned Aerial Vehicle a great value, but also presented some limitations.
