In addition to automated inspection processes, AutoInspect also integrates AR-supported manual inspection by a worker. Defects are detected and registered by finger pointing.

Digitization and sustainability - these are the key topics of the world's most important industrial trade fair, setting clear impulses for the transformation of business and industry - towards digitized, climate-neutral and sustainable value creation.

AutoInspect –digital 3D twin for systematic sensor deployment planning and sensor data fusion

The exhibit, in which the Visual Inspection Systems department is involved, exemplifies an infrastructure solution that combines various inspection methods such as ellipsometry or deflectometry and merges the recorded features with metadata with pinpoint accuracy on a 3D model of the test specimen - in this case a car body. On this basis, a wide range of evaluations are possible, from simple statistics to AI/ML methods. The principle is explained in detail at the trade fair booth - a live link to the Karlsruhe research factory shows the current status of our solution.

This exhibit can be found at the Fraunhofer-Gesellschaft joint booth. Visit us: hall 5, booth A061.

The miniature version of a bulk sorting system: the name TableSort® definitely says it all, as the system actually fits on a table in terms of size.

A sustainable society, the renunciation of fossil raw materials, climate-neutral processes - the chemical industry has committed itself to these goals. For the industry, this means a huge challenge within the next few years and decades. Researchers from a total of seven Fraunhofer Institutes are pooling their expertise in the lead project "Waste4Future" to make these goals tangible. At the "K trade fair", the team of experts will show how new possibilities for recycling can be created and, at the same time, how high-quality starting materials can be produced as a "green" resource for the chemical industry.

We are represented with our miniature bulk material sorting system TableSort®. It serves as an example of a smart factory system that sorts plastic waste.

The inspection of surfaces is a classic field of industrial image processing and has been proven in many applications for many years.

Image Processing for Surfaces - Advances in technology not only enable ever higher inspection speeds and more compact systems, but also, in addition to the evaluation of two-dimensionally recorded textures, the complete recording of complex 3D surface structures down to the nanometer range. Furthermore, the rapid evaluation of colored, patterned, transparent, highly reflective or mirroring surfaces is possible. In the seminar, different inspection and analysis methods will be presented for this purpose.

We are involved with the following contributions:

Image acquisition in surface inspection
