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.

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.

The Forum is an annual event organized by the European Machine Vision Association - EMVA. The aim is to promote interaction between the machine vision industry and academic research in order to learn from each other, discuss the latest research results and application problems, learn about new application areas and discuss research collaboration between industry and academic institutes. The overall aim is to accelerate innovation by putting new research findings into practice more quickly. The focus here is on methods, systems and applications based on images of the "invisible". Of particular interest here are sensor systems and methods for capturing image data as well as procedures for evaluating them.

Dr.-Ing. Johannes Meyer, Head of the Variable Image Acquisition and Processing research group at the IOSB will give a lecture:

Physics-informed Image Reconstruction

In many imaging applications, it is necessary to obtain information indirectly from the captured images, i.e. we have to solve an inverse problem. A well-known example is the deconvolution problem, which must be solved when using lensless cameras or defocused optical systems, for example.

On October 17, 2025 at 11:25 am.

The forum is an initiative of the HCI at Heidelberg University for further education, networking and information exchange between research and industry.
