Dr Gerhard Reitmayr

Since June 2009 I am professor at the University of Technology Graz, Austria. This webpage will not be updated in the future.

I am a research associate in Cambridge University Engineering Department where I am working with Dr. Tom Drummond in the Information Engineering Division. Before that I studied at Vienna University of Technology where you can find some information about past projects. My work here is funded by The Boeing Company and more recently by the EC project IPCity.

Phones are an interesting platform for augmented reality, but very limited in computing power. Here we ported two different feature matching/classification methods to mobile phones to enable tracking a planar object.

Making use of SLAM methods, this work demonstrates high level annotations in unknown environments. A user where an annotation should be placed and the SLAM system measures the annotation location and shape to create the graphical overlay. It provides high-level primitives such as rectangles and circles.

This system provides a comprehensive solution for outdoor tracking. It provides a robust solution using OpenGL a model of the enviroment is rendered and used for fast edge tracking. Combined with inertial sensors, recovery mechanisms if tracking fails and initialisation coping with large GPS errors.

Printed paper maps provide high resolution displays but cannot change. Using a camera-projector setup we track and augment a printed map to overlay changing information onto the map. Various tangible tools allow to interact with the system.

This work tracks areas with less visual interest based on feature density and automatically computes label layout for Augmented Reality information displays taking constraints set by the application designer into account.
