Resumo:
With the arrival of Industry 4.0, companies have adopted digital twins to improve their production processes and the working conditions of their employees. Digital twins are generally associated with three-dimensional models and allow planning, data extraction, simulation, and training based on current conditions. Unfortunately, incorrect or outdated digital twins can lead to errors and information mismatch, which takes away all the advantages of the virtualization and computerization process, ruining any comparisons with reality. In contrast, information-rich digital twins allow simulations and data extraction to be more faithful to reality. Currently, technologies capable of enriching the information of digital twins are scarce, as it is a procedure that takes time due to the need for expert analysis, costs, equipment, and specific tools. Resources such as 360 degrees photographs, videos, and 3D models can be used to perform an evaluation and update the digital twins. However, temporal differences, environmental conditions, and human errors between the images and the model can generate confusion during the transfer and connection of information. This work presents a tool that explores the advantages of combining 360 degrees photographs with 3D models to generate as-built digital twins. Each image can be adjusted to a location within the model s coordinate system, allowing changes to axes and field of view. During navigation, it is possible to navigate the model and the user-created positions of interest freely. In addition to visualization, the tool proposes a more effective interaction to annotate between models and 360 degrees photographs to verify consistency or add new information to the digital twin. These interactions are essential for inspection and maintenance, such as evaluating parts, analyzing current conditions, or creating comparisons between planned and actual.
