An as-built digital twin visualization and generation tool using with three- dimensional CAD models and 360o images of industrial facilities.

Resumo

Today, many companies use digital twins as part of their activities. Digital 3D models enable planning,
data extraction, simulations, and training on local conditions. However, an incorrect digital twin may induce errors
that offset all possible advantages of the digitalization process. On the other hand, an information-rich digital twin
allows simulations and data extraction to be faithful to reality. Enriching the data of a digital twin is a process
that takes time, expert analysis, costs, and equipment, making the update process difficult. Photos, 360o images,
and 3D models can be used to support evaluation and updates. However, differences between pictures and models
yield confusion when transferring and connecting information. This work presents a tool that explores the benefits
of combining 360o images of industrial facilities with three-dimensional CAD models to generate a correct as-built
digital twin. This tool has an interface capable of displaying three-dimensional models of an industrial plant in
conjunction with 360o photographs, allowing the user to navigate an augmented reality environment. GPS or simple
annotations in the 360o images allow an easy manual camera calibration interactive process. The tool proposes an
effective interaction to make annotations in the CAD models and the 360o photographs.
