In 2006, I graduated with honors in studies formerly known as Media Systems at the Bauhaus University in Weimar in June 2006. Therefore, I was allowed to call myself a "Diplom-Mediensystemwissenschaftler".
From July 2006, I was working as a PhD student in the Computer Graphics Group of Prof. Marc Alexa at the Technische Universität Berlin. In May 2012, I defended my PhD thesis titled "Real-time depth imaging". The dissertation received an overall assessment of "magna cum laude" and allows me to call myself "Doktor der Ingenieurwissenschaften" (Dr.-Ing.).
In July 2012, I moved to Freiburg and joined the SICK AG in Waldkirch. There, I joined the 3D Compact Systems team as software development engineer. In 2017 I became head of the Software Design group.
Since September 2021, I am professor for Computer Vision in media applications at Hochschule Furtwangen University. Please check my personal page there for future updates.
Combining time-of-flight with stereoI work on this topic for about two years. It all started with a student project "Scanning real world objects without worries". Subsequently, I supervised the diploma thesis of Antoine Mischler who focusses on real-time stereo and depth estimation for augmented reality applications. More information the project can be found here. Don't hesitate to contact me if you are interested in my work. |

Diploma thesis: "Weighting in Laplacian Mesh Editing"This diploma thesis has been created in cooperation with DaimlerChrysler. A software has been developed that supports the assembly simulations performed by design engineers. An assembly simulation examines the collision of units. These virtual units are presented as triangular meshes and they are currently solid and undeformable in contrast to real world objects. This software simulates the natural solidness of the units by allowing to deform the virtual objects in a natural manner. To do this, a Laplacian mesh editing scheme has been implemented. Laplacian mesh editing allows to deform 3D objects while their surface details are preserved. Detail preservation is an important feature because it allows the simulation of realistic
deformations. |

Optical TrackingDuring two projects we worked on tracking input devices for virtual reality applications. In the first part, we tracked LEDs an reconstructed their position in 3D space with a multi view setup of several small firewire cameras. In the second part, we worked on tracking colored objects with a single camera and on computing the position of a rack of laser pointers by tracking their light spots and calculate back their origin. |
GasblasenIn industry gas bubbles are used to clean oil. The path of these bubbles want to be predictable. In our project we analyzed the path of a bubble in a water tank captured by two video cameras. We described the path as a spiral in order to minimze the error while having a simple description of the path of any further bubble in any other liquid. Unfortunately, we never received more data to prove our system. |
HolographicsFirst, I did some research on digital holography. In order to print a hologram we took a picture of a car's headlamp from each viewing angle (see video). The whole process is described in the term paper and the slides of our presentation. I joined the holographics research project in 2004. The aim of the project was to combine holograms with interactive computer graphics. See the website and the following paper for details: |
MPGI 2 - Methodic and practical basics in computer science (part 2), together with Clemens Eppner and Sebastian Höfer, I lead a group of student tutors for organizing and executing the tutorials for this first year (2nd semester) course. I filled in for Prof. Oliver Brock for some lectures on graph theory.
Processing Digital Camera Images - A seminar about processing camera images in a modern way. I again supported Mathias Eitz in organisation and leading the seminar. My part was to organize the basic talks of the students.
Computer Graphics 1 - A basic course along the rendering pipeline. I supported Ronald Richter with the exercises.
No teaching due to parental leave.
