Resumo: | Mobile handheld devices such as smartphones have become increasingly powerful in modern times. Because of this, there has been a surge in 3D graphics-heavy mobile applications that aim to provide immersive experiences. An example of this phenomenon would be Augmented Reality (AR) applications, which have been increasingly popular and offer a wide array of use-cases. The ability to merge the real world with the virtual world seamlessly using the built-in camera of the smartphone brings a whole new world of possibilities, which makes it interesting to explore how such a technology could be used to solve real-world problems. This dissertation focuses on applying this technology in the field of urban maintenance. To do so, a mobile AR application was developed, designed to be used by urban maintenance workers as a field-assistance tool. Using any standard smartphone camera, the developed system can accurately detect any equipment and augment it with relevant information and step-by-step instructions on how to do any required maintenance jobs. Alongside this mobile application, a desktop application was also developed with the purposes of creating and authoring the data and augmentations that should be displayed during a given job, called Archer. Lastly, this dissertation proposes a novel approach to automatically detect and minimize the amount of points (checkpoints) at which the application will ask the user to perform a new equipment recognition, which are useful in order to maintain tracking stability as the user modifies the real-world object during the course of the job. The experiments and user tests conducted during the final stages of this dissertation demonstrate the accuracy and practicality of the developed systems, proving that they can effectively be used to greatly improve the workflow of urban maintenance workers. |

Como tal, tem havido um grande aumento na quantidade de aplicações móveis 3D com o intuito de fornecer experiências imersivas. Um exemplo desse fenómeno são as aplicações de Realidade Aumentada (RA), as quais se têm tornado cada vez mais populares, oferecendo um vasto leque de casos de uso. A habilidade de fundir o mundo real com o mundo virtual através da câmara de um smartphone traz todo um novo mundo de possibilidades, o que torna interessante a exploração de como esta tecnologia pode ser usada para resolver problemas no mundo real. Esta dissertação foca-se na aplicação desta tecnologia na área da manutenção urbana. Nesse sentido, foi desenvolvida uma aplicação móvel de RA projetada para ser usada como uma ferramenta de assistência em campo por trabalhadores de manutenção urbana. Usando qualquer câmara de smartphone, este sistema consegue detetar qualquer equipamento de forma precisa e aumentá-lo digitalmente com informação relevante e instruções passo-a-passo de como fazer qualquer trabalho de manutenção. Juntamente com esta aplicação móvel, também foi desenvolvida uma aplicação para desktop — chamada Archer — com o intuito de criar e validar os dados e os objetos digitais que serão apresentados na aplicação mobile durante o curso de um trabalho de manutenção. Por fim, esta dissertação apresenta uma nova solução para a deteção e minimização automática dos pontos (checkpoints) em que a aplicação móvel deverá pedir ao utilizador para efetuar um novo reconhecimento do equipamento, os quais são úteis para manter um tracking fiável e estável à medida que o utilizador vai modificando o equipamento durante um trabalho. As experiências e testes com utilizadores efetuados na fase final desta dissertação demonstram a precisão e praticidade dos sistemas desenvolvidos, provando que estes podem efetivamente ser usados para melhorar o workflow dos trabalhadores de manutenção urbana.Correia, NunoBirra, FernandoRUNRodrigues, André Oliveira2022-02-10T10:38:57Z2021-102021-10-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/132667enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T05:11:21Zoai:run.unl.pt:10362/132667Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:47:33.715880Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
