Finlay, Andrew, Rouillard, Vincent, McAndrew, Alasdair and Zayegh, Aladin (2009) Novel encoding and fiducial techniques for visual positioning beacons. In: Proceedings of the 4th International Conference on Autonomous Robots and Agents, Feb 10-12, 2009, Wellington, New Zealand. IEEE, Palmerston North, New Zealand, pp. 408-413.


A novel barcode system has been developed that allows for positioning using machine vision techniques. The barcode is applied to a positioning beacon and includes features that allow for fine position resolution, variable sized code spaces and rotational and perspective invariance. Beacon position may be found using standard stereo techniques. The correspondence problem is overcome by applying a unique identifier to each beacon allowing wide baseline stereo.
