Research

My research focus can be summarized under the notion "management of tracking and tracking accuracy".

This work is conducted on behalf of the trackframe project and comprises the integration of various kinds of sensors for the purpose of 6 DoF pose / position / orientation tracking in wide-area environments. The basic concept are spatial relationship patterns which represent recurring tracking/calibration/fusion problems and can be solved by a certain algorithm. Spatial Relationship Patterns can be combined to form a graph structure called the Spatial Relationship Graph. It represents the spatial relationships that are relevant for a certain tracking environment and at the same time provides all information that is needed to instantiate a dataflow which derives the spatial relationships needed by the AR/VR application. These core concepts are provided in terms of the Ubitrack library.

One major aspect of my research is the question how these concepts can help to facilitate design and maintenance of complex tracking environments. To this end, a graphical planning and analysis tool called trackman (trackframe manager) is being developed. It comprises functionality for offline planning and configuration of tracking environments in terms of Spatial Relationship Graphs. Furthermore, concepts are being developed which allow for the evaluation of accuracy of tracking data within an existing tracking environment. Different sensors can be tested and the results can be compared.

In the future, it shall also be possible to perform accuracy analysis based on virtual environments, i.e. without the need to use real sensor data. Monte-Carlo simulations could provide a generic method to evaluate hypothetical setups and compare them against each other.

My Ph.D. advisor is Prof. Gudrun Klinker.

Students that are interested in this topic and want to contribute in terms of a Bachelor thesis, Master thesis, Diplomarbeit, SEP, etc., are always welcome in my room (03.13.040) to talk about further details.
