Spectral Imaging in Agrifood Application

Speaker: Benedikt Fischer

As part of the OCM-2023 conference, we will present, in the laboratory area of Fraunhofer IOSB, the methods developed in the PA-NIR-Sort project, in a live sorting demonstration. Planned is the purification of a crop stream by the removal of Greiskraut as a representative of the plant group of PA-formers. The goal of this project is "Detection and removal of pyrrolizidine alkaloid-containing weeds from crop plants after harvest using PA-NIRSort". A first demonstrator, based on the Fraunofer IOSB laboratory system TableSort®, has been upgraded for the task.

Fields of application: Tea, herbs and feed manufacturers

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 fifth time in March 2023.

Speaker: Chia-Wei Chen

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.

Machine Learning as a Key Technology for 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. 

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.

The Industrial Association for Food Technology and Packaging e. V. (IVLV) working group "Preservation of Food Quality" is dedicated to understanding quality changes in foodstuffs depending on their composition, the degree of processing and the packaging and storage conditions. On this basis, concepts for shelf life extension and process hygiene as well as rapid methods for quality assessment are developed.

The event is aimed at food manufacturers and suppliers, filling and packaging machine manufacturers and the retail trade.

We will be represented with a presentation:

Spectral Imaging for Food Inspection.

Referent: Robin Gruna on 05/17/2023, 09:40 a.m.

Holistic recycling & innovative assessment approaches of plastic-containing waste stream

At this online event, the Fraunhofer lead project Waste4Future will provide insight - alongside experts from industry - into how networked recycling processes and technologies for plastic-containing waste can make a valuable contribution to achieving the Zero Pollution Act action plan.

The Visual Inspection Systems (SPR) department is represented there with a presentation:

New methods and sensor technologies for sorting black plastics and age characterisation

Speaker: Georg Maier 01:45 p.m.

The SpectroNet Collaboration Conference 2023 (SCC) in Erfurt is a two-day international conference which is scientifically as well as technically oriented and presents the latest developments and trends for robust perception and measurement of object and system conditions in the fields of production, recycling, medicine and nature.

Real-world Machine Vision Challenges

Coping with Variability and Uncontrolled Environments

Machine vision solutions provide great value to end-users, but also must function well in real-world environments like agriculture, environmental monitoring, industrial and medical applications. Depending on the application at hand, specific challenges arise which concern the variability of the vision task as well as possible disturbances or operational conditions like for example large varieties of disturbances, variations of the objects to be inspected or unknown camera poses. 

We are represented with two lectures:

Closing the gap: Tracking of bulk good from sensor to actor using event-based vision in sensor-based sorting

Referent: Paul Bäcker

A Concept Study for In-Field Phenotyping and Modeling for Grapevine Yield Prediction

Referent: Benedikt Hofmann

Innovative technologies for industrial quality assurance with image processing

Motivation

The Technology Days of the Fraunhofer Vision Business Unit offer a broad overview of the spectrum of practice-relevant technologies in image processing and optical metrology and reflect the current state of the art. In addition, realized applications are described and emerging future perspectives are highlighted.

Target audience

The event is aimed at those interested in the topic of image processing from almost all sectors who are looking for information on the practical use of these technologies in an industrial environment and also at representatives in the field of research and development. The accompanying trade exhibition is a sought-after forum for deepening the dialog with the experts and for establishing new cooperations.

We are represented with a presentation (German only):

Künstliche Intelligenz in der Landwirtschaft

Referent: Robin Gruna

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.
