Title: | Robust Global Tracking Using a Seamless Structured Pattern of Dots | Authors: | JORISSEN, Lode MAESEN, Steven DOSHI, Ashish BEKAERT, Philippe |

Traditionally, larger scenes are provided with multiple markers with their own identifier and coordinate system. However, when any part of a single marker is occluded, the marker cannot be identified. Our system uses a seamless structure of dots where the world position of each dot is represented by its spatial relation to neighboring dots. By using only the dots as features, our marker can be robustly identified. We use projective invariants to estimate the global position of the features and exploit temporal coherence using optical flow. With this design, our system is more robust against occlusions. It can also give the user more freedom of movement allowing them to explore objects up close and from a distance. | Notes: | Jorissen, L (reprint author), Hasselt Univ tUL iMinds, Expertise Ctr Digital Media, Wetenschapspk 2, B-3590 Diepenbeek, Belgium. lode.jorissen@uhasselt.be; steven.maesen@uhasselt.be; ashish.doshi@uhasselt.be; philippe.bekaert@uhasselt.be | Keywords: | optical tracking; structured pattern; projective invariant; augmented reality | Document URI: | http://hdl.handle.net/1942/18079 | ISBN: | 978-3-319-13968-5 | DOI: | 10.1007/978-3-319-13969-2_17 | ISI #: | 000354698400017 | Category: | C1 | Type: | Proceedings Paper | Validations: | ecoom 2016 |
