“…In the literature, works related to the method proposed in this research, where the use of UAVs (as well as in combination with scanners), point cloud, and BIM for facility management is integrated. The applications are focused on knowing, at different levels of detail, the condition of structures such as bridges [ 44 ] and towers [ 45 ], as well as uses for heritage BIM (HBIM) [ 46 , 47 ]. The capture of damage in these works is obtained from non-invasive methods in contact with the structure and the identification from images obtained with the UAV.…”

The maintenance of port infrastructures presents difficulties due to their location: an aggressive environment or the variability of the waves can cause progressive deterioration. Maritime conditions make inspections difficult and, added to the lack of use of efficient tools for the management of assets, planning maintenance, important to ensure operability throughout the life cycle of port infrastructures, is generally not a priority. In view of these challenges, this research proposes a methodology for the creation of a port infrastructure asset management tool, generated based on the Design Science Research Method (DSRM), in line with Building Information Modeling (BIM) and digitization trends in the infrastructure sector. The proposal provides workflows and recommendations for the survey of port infrastructures from UAVs, the reconstruction of digital models by photogrammetry (due to scarce technical documentation), and the reconstruction of BIM models. Along with this, the bidirectional linking of traditional asset management spreadsheets with BIM models is proposed, by visual programming, allowing easy visualization of the status and maintenance requirements. This methodology was applied to a port infrastructure, where the methodology demonstrated the correct functionality of the asset management tool, which allows a constant up-dating of information regarding the structural state of the elements and the necessary maintenance activities.

“…To overcome this problem, as shown in Fig. 1 (b), a remote control inspection has been considered in which only the UAVs are dispatched to the infrastructures, and the pilot who remains at the base operates the UAV remotely to inspect the infrastructures [4]. Since the pilot is not dispatched to these sites, travel costs and time spent with the pilot can be reduced.…”

Inspections of infrastructure facilities using unmanned aerial vehicles (UAVs) are expected to improve operational efficiency. However, the costs of pilot training and travel to infrastructures are the problem. This letter proposes a Migratory UAV system (MiUAV) with multiple ports for automated infrastructure inspection. Multiple ports capable of accommodating and recharging UAVs are placed, and the UAVs can travel autonomously to distant destinations by using these ports. A routing algorithm not using edges to ports with high utilization ratio is also proposed. Computer simulations evaluate that the arrival time can be reduced while maintaining the same average number of hops.

“…Possível Utilização de Métodos de Apoio à Georreferenciação. Como o objetivo deste trabalho passava pela exportação do modelo fotogramétrico para um programa de modelação BIM 3D, importava essencialmente a precisão relativa [18], podendo utilizar-se apenas tie points de relevância da nuvem de pontos, para melhorar a qualidade do modelo fotogramétrico [19], [20], e checkpoints, para medir a precisão [21], abdicando-se assim de pontos de controlo terrestres (GCPs) [22]. Foram então utilizados 6 manual tie points e 6 checkpoints, aproveitando marcações de jogos infantis e vértices de portas, janelas e cobertura, obtendo-se um erro bastante reduzido e, consequentemente, garantindo-se bastante precisão.…”

“…Modelo Fotogramétrico. Com base nas imagens georreferenciadas obtidas aquando do levantamento, procedeu-se à reconstrução 3D duma nuvem de pontos [20]. Para isso utilizaram-se os programas Agisoft Metashape e o Pix4Dmapper, que são capazes de processar os dados inseridos e reconstruir objetos 3D a partir de imagens [15], [23].…”
