Digital twins and immersive mixed reality have been improving the human-centered digital transformation inside the automotive industry context. In computer vision, the photogrammetry’s based techniques for 3D environments reconstruction turns possible to create the virtual models of real scenery only based on a set of digital images. This paper addresses the problem to project and update the shop floor layouts by 3D mapping of the real environment in operation to its corresponding digital twin. Inside the industry plant we come across objects of several sizes, shapes and layouts that demand so much time for create a digital twin model by manual measurement devices as tape measure and clipboard to annotate the length, distances and angles. From photogrammetry by images, we can recreate this layouts and objects with assertiveness, quickness, accurate and rich of details without drawing it by hand in a CAD software. Thus, we propose an automated method to shop floor layout digitalization and DT creation where humans can interact to apply changes in the modeled equipment’s structure in order to simulate the different arrangements before the shopfloor changing in a real industrial scenario. The text presents the novelties in 3D representation to immersive aplications, discusses the feasibility and evaluation of proposed method

Modular architectures for Industrial Augmented Reality (IAR) applications allow more flexibility and can lower the barrier of entry, compared to cus-tom-built applications dominant today. This contribution presents a data management approach for such architectures. Work plans are converted into a presentation-independent format that can be consumed by the system. Based on available modules and capabilities, related data, like CAD mod-els, images, or descriptions, are automatically converted into a format suita-ble for the modules responsible for presenting the content. This can include converting a CAD module into a tessellated format, but also generating a rendering in cases where 3D models cannot be display, e.g. in a projection-based AR experience.

In IAR applications, the position of the displayed content in the users surrounding is an important aspect. For industrial contexts, this mostly re-lates to presenting content at specific parts of larger assemblies. This contribution shows how different combination of existing AR tracking technologies, in addition to CAD data of such assemblies, can be used to setup flexible IAR systems.

Mixed reality technologies and digital twins have been widely applied when the objective is to create immersive virtual environments, especially when it comes to the industrial context. Industries are increasingly looking for ways to update the new 4.0 reality and, with the use of scenario’s virtualization technologies, it is possible, for example, to train employees or people responsible for the development and creation of new solutions to digitalization in production systems for stakeholders. In this context, the article presents a project for the application of mixed reality and digital twin to create an immersive virtual environment for training employees at a company focused on the electromechanical area, more specifically on the maintenance of machines and equipment for the electrical substations at the headquarters located in the city of Curitiba - Brazil. The application’s environment, in the diary activities, cannot be accessed with a certain frequency due to risks and the impossibility of stopping the manufacturing process. Thus, the work proposed a method to create immersive training sceneries based on Microsoft Hololens technologies in order to prepare the employees to be able to act on maintenance after virtual training.
