| Abstract: | Localization of an agent is a fundamental issue in a full-body immersive VR product. The agent's absolute position has to be correct to render the virtual world correctly. In this paper, an agent localizes himself inside a football field bordered by beacons with a 10 meter relative spacing, using only an optical camera. The beacons are mapped and identifiable. The agent triangulates its own position by measuring bearings to the beacons. A simulation model of the field is built and it is investigated with what accuracy the position can be triangulated. The simulation model is refined with a preliminary experiment investigating the camera's field of view and measurement errors of the bearings. We show that this system provides sub-decimeter accuracy but also suffers from large blind spots, poses where the location can not be triangulated. Recommendations are provided on how to shrink the size of the blind spots. |
