Abstract
High position and orientation accuracy is required in augmented reality systems.This paper presents an extension to the well known XVision library for real-time tracking. We implement a real-time sub-pixel accuracy edge tracking algorithm estimating edge position and orientation based on “virtual edge” localization in a 5 x 5 window. In addition, we give a simple yet efficient heuristic for identifying corners. Experiments demonstrate results for sub-pixel edge and corner tracking superior to the original XVision primitives.
This work has been supported by the Austrian Science Fund (FWF) under contract number P-12074-MAT. The “Studierstube” is a joint project with the Vienna University of Technology. We want to thank Joachim Steinwendner for his input in designing the sub-pixel tracking algorithm.
