Abstract
In this paper, we present an overview of several visual tracking methods for industrial augmented reality applications. We show that no universal algorithm can deal with the large number of possible scenes, and that the different methods have to be seen as complementary approaches that all have their strengths and weaknesses. The main difficulty, then, consists in combining existing building blocks in the right manner so that the overall system enables stable tracking. This paper addresses each phase of the tracking, i.e. Initialization, Tracking, Re-Initialization, and proposes a first choice of appropriate algorithms. Finally, a global system is designed, tested and evaluated with help of video sequences of different real environments.
