Student assistant in the field of hyperspectral acquisition of 2D and 3D objects

The Fraunhofer-Gesellschaft (www.fraunhofer.com) currently operates 76 institutes and research units throughout Germany and is a leading applied research organization. Around 32 000 employees work with an annual research budget of 3.4 billion euros.

The Competence Center of Cultural Heritage Digitization at Fraunhofer IGD develops and automates 3D scanning technologies to allow for automatic 3D reconstruction of cultural heritage and industrial objects.

Different acquisition devices are used depending on the object properties and quality requirements.

Using a special hyperspectral camera, a material behavior acquisition device is extended from the visible into the hyperspectral domain.

What You Will Do

Initially, you will dive deeper into the field of hyperspectral imaging and get to know an existing hyperspectral camera and its output data structure, with the goal of analyzing different materials for their response in different wavelength domains, beyond the visible (RGB color space).

As a next step, an existing measurement device for optical material behavior (i.e. light-surface-interaction of objects for varying light and observer directions) will be extended beyond the visible domain, with the goal of capturing effects of changing wavelengths on incoming and resulting outgoing light. To this end an object is illuminated automatically from various hemispherically distributed directions, and its optical response is captured in the spectrum of 470 - 900 nm is recorded in up to 1000 bands.

The application of this technology is to offer a versatile analysis tool, such as for researching traces left by tools used in the creation of a painting, or for detecting the various constituent materials of an object, thereby aiding in the identification of fraud or defects.

What You Bring To The Table

• Very good C programming skills
• Strong knowledge in mathematics and linear algebra
• Proficient English skills
• Precise, responsible, independent working style
• Experience in Computer Vision
• Experience with the frameworks Qt and OpenCV is advantageous
  
  

What You Can Expect

The weekly working time is 10-20 hours. The position is initially limited to three months, an extension is intended.

We value and promote the diversity of our employees' skills and therefore welcome all applications - regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, sexual orientation and identity. Severely disabled persons are given preference in the event of equal suitability. Remuneration according to the general works agreement for employing assistant staff.

With its focus on developing key technologies that are vital for the future and enabling the commercial utilization of this work by business and industry, Fraunhofer plays a central role in the innovation process. As a pioneer and catalyst for groundbreaking developments and scientific excellence, Fraunhofer helps shape society now and in the future.
