Data-driven Sensor System for Quality Assessment of Fruit with Hyperspectral Imaging an AI

Referentin: Anna Taphorn

The state of the art in optical characterization of materials is advancing rapidly. New insights into the theoretical underpinnings of this research have been gained and exciting developments have been made in practice, driven by new applications and innovative sensor technologies that are constantly evolving.

The great success of past conferences proves the need for a platform to present, discuss and evaluate the latest research results in this interdisciplinary field. For this reason, the International Conference on Optical Characterization of Materials (OCM) will be held for the sixth time in March 2025.

We are represented with 1 lectures:

PAH Detection in Road Surface Residue Using Various Hyperspectral Imaging Sensors with Detection Spray Proxy

Referent: Paul Bäcker

In addition, 5 posters will be presented:

Robust model development for HSI-based characterization of post-consumer plastics

Referent: Lukas Roming

Adaptive architectures for semantic segmentation in the field of sensor-based sorting systems

Referent: Felix Kronenwett

Non-Destructive Quality Control using a Multi-Sensory Fruit Scanner with NIR and Microwaves

Referent: Anna Taphorn

Optimizing Near-Infrared Spectroscopy for On-line Grape Must Quality Assessment: Addressing the Impact of Suspended Solids

Referent: Pascal Gauweiler

Inverse rendering for material characterization

Referent: Johannes Meyer

inVISION Day Metrology 2025 is a digital conference focusing on the latest developments and trends in metrology.

Dr.-Ing. Johannes Meyer, head of the Variable Image Acquisition and Processing research group at IOSB and winner of the EMVA Young Professional Award, will open the event with the keynote:

Unconventional Optical Metrology - New Possibilities Beyond Classical Systems

This presentation will explore new ways of designing optical metrology systems, such as end-to-end learning, lensless imaging and light field methods.
This will be followed by sessions on 3D scanners, inline metrology, surface metrology and CT & Xray.

Girls'Day aims to make technical, scientific, trade and IT professions in particular more attractive to girls and young women.

In addition to practical experience, female role models in STEM subjects are the key to encouraging girls to learn a profession in this field. The key message of the 2017 Microsoft study was that girls can be inspired to pursue STEM disciplines through female role models and more practical experience.

We are participating with a workshop:

👉 Become a technical tinkerer and start soldering! 🔧✨ 

"Solder your own nameplate and build an astable tilt stage (flashing circuit)."
  Supervisor: Marcel Göttel & Britta Ost 
  Link to the event page (only in German): Home | Girls'Day

As the only major international sensor and metrology conference, SMSI brings together intelligent sensor technology and instrumentation, digitalization-oriented measurement science with cognitive features as well as modern quantum technology-based metrology including the secure digital exchange of certificates.

This year's conference will take place in Nuremberg from May 6 to 8. On the final day of the conference Paul Bäcker from the department Visual and Inspection Systems will be giving a lecture entitled:

Motion Compensation of Event-Streams for Multitarget Tracking in Sensor-Based Sorting

Session: B6 Event Based Vision
Time: 14:50-15:10 

The most important international trade event for all topics relating to measuring and testing technology as well as vision technology, image processing and sensor technology is the annual control trade fair in Stuttgart.

Quality assurance with image processing 

This time Fraunhofer IOSB presents with the department Visual Inspection Systems the exhibit:

Light Field Inspection-light field based light source for flexible use

In the presented inspection technology, objects with complex geometry are illuminated by a specially adapted "light recipe" in such a way that relevant structures can be detected with maximum contrast. The optimum light field for this task is determined by an algorithm that intelligently adapts the illumination modalities to the individual object geometry. This approach is groundbreaking for a future generation of inspection systems, as here image evaluation and illumination are jointly optimized for the most efficient inspection system possible.

Inspection of (partially) reflective surfaces with deflectometry for quality assurance

However, the inspection of reflective surfaces poses special challenges in practice: On the one hand, most common surface inspection methods, such as fringe projection, rely on diffuse reflection. On the other hand, the results of such methods cannot easily be used to evaluate reflective surfaces, as the customer assesses the quality based on reflections of the surroundings in the surface. The deflectometry method closes this gap in measurement and testing technology and offers the possibility of applying objective standards in quality assurance using simple means.

Joint booth of the Fraunhofer Vision Business Unit

We would like to invite you to get an overview of the new developments of the Fraunhofer Business Unit Vision and the exhibits at the joint booth of the Fraunhofer Business Unit Vision.

Visit us: Hall 7/Stand 7301

The aim of this conference MVML 2025 is to bring together scientists from all over the world to present advances in the relevant fields. A suitable environment that promotes the exchange of ideas and information to develop new collaborations and connect experts on the fundamentals, applications and products in machine vision and machine learning.

The Visual Inspection Systems department is participating with the following presentations:

👉 A Comparative Evaluation of Vision Language Models for Waste Classification in Few-Shot Settings

Program preview

• Automation of construction and logistics
  From autonomous construction and work machines to autonomous transport vehicles: we give you an overview of the state of the art and offer you the opportunity to try out our systems live.
• Material evaluation and sorting
  Comprehensive processing of demolition waste can only be successful if the material is optimally evaluated and sorted accordingly. We will show you how this can be done in a highly automated and reliable manner.
• Digital product passport
  The digital product passport is the basis for the traceability of materials and effective reuse of raw materials in the recycling process. We will show you the details of how to implement this important digitalization module.
• Contributions from research and industry
  Find out about the latest research results at first hand and see our solutions in action.

Discuss the future of civil engineering with us and experts from industry and application!

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.
