Evolution of a Tracking System
This chapter describes the evolution of a feature-based tracking system developed by metaio. One of the reasons that started the development of the system was the first tracking contest at the International Symposium of Mixed and Augmented Reality (ISMAR) in 2008, which was designed to fairly evaluate different tracking systems. We present the toolchain we conceived to solve common problems like referencing to another coordinate system or creating a map of the environment from photos; we also describe the principles of our tracking method which, in contrast to the methods of all other contestants, was robust enough to use exactly the same parameters for all scenarios of the tracking contest held within the German research project AVILUS1 but at the same time was the most accurate. The ultimate goal of development is its integration into an end consumer product.
Our thank goes to Daniel Pustka and Gudrun Klinker who conceived and organized the ISMAR 2008 and 2009 tracking contests as well as Björn Schwerdfeger who together with Gudrun Klinker mainly organized the AVILUS Tracking contest. Futhermore, we are thankful to Harald Wuest, Mark Fiala, Peter Keitler and Sudeep Sundaram for disclosing their technology and for valuable discussions about their view on the tracking contests.
