인더스트리 4.0을 위한 증강 현실

The final inspection and quality testing of complex, three-dimensional components still poses great challenges for production employees, especially in series production with particularly short cycle times. Not only in terms of the time within which these are carried out, but above all in terms of the ergonomics of the workplace itself. Within a very short time, workers have to manually inspect and rework very large, three-dimensional components. We have taken on the solution to this problem and developed a suitable dynamic laser projection process, taking into account a wide range of factors, including time, quality and ergonomics. This innovative laser projection process is already being used successfully in the BMW paint shop. Here, areas to be reworked are projected over the entire car. For this purpose, a network of five WERKLICHT projectors works together in each finishing booth. The outer skin of the car body is divided into clearly defined projection areas, each of which is assigned to a projector. The individual projectors are coordinated and controlled by a local analog PC located next to the finishing booth. Another important innovation for the project was our WERKLICHT software.

Siemens has already been relying on our dynamic laser system in locomotive construction for years. In search of a more flexible solution and a replacement for heavy and bulky aluminum stencils, as well as taking into account the optimization of quality and workflows, the decision was made very quickly to purchase our WERKLICHT system. Not only the ease of use of our system was convincing, but also numerous other advantages: The expensive production of new positioning templates was no longer necessary. As a result, the costs for the corresponding maintenance and storage of the bulky templates were also eliminated. And the employee no longer had to transport the heavy and very large templates to the workpiece and place them there, which was not only an enormous effort for the worker each time, but could also lead to quality losses.

In the research project “VIGITIA” (Networked Intelligent Objects through, on and around interactive tables in everyday life), we are working with the University of Regensburg and Bauhaus University Weimar to develop an intelligent lamp that projects information and digital tools onto dining tables, desks or work surfaces such as a workbench. The system is designed to recognize “intelligent” and “less intelligent” objects and integrate them into the interaction at the table – from smartphones to spoons to tools. However, the tables themselves are hardly changed in the process. The goal of this research project is therefore to make analog objects more intelligent in the context of a table. Specifically, this means opening up interactive tables to support everyday activities for commercial and scientific practice by identifying and solving, among other things, user requirements and usage contexts as well as technical challenges such as projection onto table surfaces and non-planar objects under everyday conditions or even the seamless and intuitive linking of existing “smart devices” (tablets, etc.) with the interactive table. However, this does not involve adding embedded electronics to individual objects. Instead, projective augmented reality (projective AR or PAR for short) is used. We at EXTEND3D are focusing on research and development on projective augmented reality and object tracking in this project. For more information about the project, please visit  http://www.vigitia.de
