International Manufactoring Technology Show
Auf der IMTS 2018 in Chicago treffen sich vom 10. bis 15. September tausende Technik-Enthusiasten, um die Trends und Technologien in der industriellen Herstellung aufzuschnappen. Auf einer der größten Messen ihrer Art präsentieren über 2 000 Aussteller ihre Lösungen für die komplexen Anforderungen im Herstellungsprozess, die durch die Industrie 4.0 einem rasanten Wandel unterliegen und schneller Anpassung bedürfen. Auch das Fraunhofer IGD stellt seine Technologien vor, das durch Mixed Reality aufwendige Anlern- oder Montageprozesse minimiert.
AR und VR für Wartung, Montage und Konstruktion
Technische Systeme wie Fahrzeuge oder Maschinen werden immer komplexer und individueller. Bisherige Ansätze zur Anleitungen von Reparaturvorgängen reichen häufig nicht mehr aus. Die Industrie sucht hierfür nach neuen Lösungen. Unsere Mixed-Reality-Ansätze erlauben es, 3D-Konstruktionsdaten optimal mit den Wartungssystemen und Prozessen zu vernetzten, um den Aufwand für die Erstellung und Durchführung der Anleitungen wesentlich zu minimieren oder gar erst zu ermöglichen.
Die instant3Dhub- und visionLib-Systeme bieten hier im Zusammenspiel eine optimale Lösungsplattform, um massive 3D-Modelldaten mit mobilen VR/AR Endgeräten und modernen Tracking-Ansätzen optimal zu verbinden.
Hannover Messe USA
Erstmals in der 70-jährigen Geschichte der Hannover Messe wagt sich diese übrigens ins Ausland: Die Hannover Messe USA, Ableger des deutschen Messeurgesteins, wird im selben Zeitraum wie die IMTS 2018 in Chicago anwesend sein. Es werden rund 550 Aussteller erwartet, die für die Deutsche Messe AG die typischen Industriebranchen der Hannover Messe bedienen. Die Deutsche Messe AG fasst im amerikanischen Markt bereits seit 2012 Fuß und will mit der Hannover Messe USA ihre Strahlkraft im September bündeln.

Augmented reality for maintenance and service support
Growing competitive constraints in industrial production result in a rising product complexity, in a large amount of product variants and in abbreviated development cycles. This complexity interferes with the maintenance strategies that have to support error recognition, repair, and overhaul with a maximum efficiency.
The required knowledge density can be supported by digitalization, if high-efficient man-machine interfaces are guiding service technicians in awareness of complex situations through difficult procedures.
Thereby, the mobility of a service technician, that often has to move in large industrial areas, has to be assured. In this context, Augmented Reality (AR) can play a major role since the service technician is using his smartphone/tablet to assess information about the maintenance tasks.
Hereby, he captures the machines to be operated with his smartphone camera. The smartphone camera recognizes on the one hand the captured machine parts, on the other hand the pose (position and orientation) of the smartphone camera in relation to the captured objects can be tracked in real-time using advanced computer vision technologies.
Core technology thereby is a model-based 3D-tracking technology that registers CAD-models within the camera images and provides a stable and robust registration of the virtual content with its associated real objects and thus is intended in particular for industrial applications. Illustrating visualizations (e.g. 3D-animations, videos, HTML-sites etc.) can be then superimposed accurately to the machines to guide the technican through complex assembly procedures.
Computer vision for inline quality control based on CAD
Computer vision based quality control has become a powerful and productive method in particular for complex inline production processes. Thereby, often problems have to be solved as ″Is part ″X″ exactly placed as specified in the CAD?″ or ″Are all components of an assembled structure considered or are some elements missing?″. To assure correct and complete assembly, camera arrays are installed around a production line capturing the assembly state of the products, with the aim to identify differences to the required target state.
Current systems often use machine learning techniques where exemplary IO/NIO-images are labeled and trained in order to establish reliable classifiers. However, this approach requires a lot of efforts for labeling and is very inflexible, as the complete process has to be repeated if any change in product design or a different product variant occurs.
To overcome this drawback Fraunhofer IGD is developing flexible quality control systems, which are ready for use with the very first product being assembled and that can be adapted to different product configurations and production processes.
The developed method uses a CAD-model-based optical tracking technique that aligns the captured real parts to its virtual counterparts in real time. Thus, high accurate tracking in multi camera arrays offers a broad application spectrum for inline quality control. The technology is deployed and approved in automotive industry but it can be extended to hetero-geneous inspection tasks in various manufacturing industries.
Augmented reality for variance analysis
In the context of the digital transformation of industrial production lines and cyber-physical systems often construction and manufacturing tasks are executed in parallel. Here, it has to be guaranteed that both worlds, the physical world and its digital counterpart do not differ in geometry.
Augmented Reality offers a high potential for advanced inspection tasks, as an inspection engineer can superimpose CAD-models exactly to the physical configurations. Thereby, advanced user interface concepts for augmented reality can be used to identify and document differences between digital and physical product configurations.
The solutions developed by Fraunhofer IGD uses model-based tracking technologies, that enable to register CAD-models to the objects captured in the camera images in real time.
By distributing the technology into client-server infrastructures, the technology can be used with automated model size reduction and data transcoding services. Interfaces to the PDM systems facilitate the deployment of the technology without the use of fully fledged and complex content preparation pipelines. The technology routinely is used e.g. in automotive industry to verify that components delivered by a supplier exactly fit to their CAD specifications.
