20140037137 | SYSTEMS AND METHODS FOR EFFICIENT 3D TRACKING OF WEAKLY TEXTURED PLANAR SURFACES FOR AUGMENTED REALITY APPLICATIONS - The present system provides an on the fly simple to complex 6DOF registration approach using the direct method. On the fly means it does not require training time, a user points a phone/camera to a planar surface and can start tracking it instantly. Simple to complex means the system performs registration in multiple levels of complexity from 2DOF to 6DOF. By increasing the complexity model the system enables more surfaces to be tracked and for surfaces that are tracked the system can avoid local minima solution providing a more robust and accurate 6DOF tracking. Even surfaces that are very weak in features can be tracked in 6DOF and virtual content can be registered to them. The system enables playing Augmented Reality games on low-end devices such as mobile phones on almost any surface in the real world. | 02-06-2014 |
