| Abstract(in English) | A Nested Marker is a novel visual marker for HMD calibration in Augmented Reality. It enables to keeping accurate calibration even when the observer is moving very close to and far away from the marker. Our proposed Nested Marker has a recursive layered structure. One marker at an upper layer contains four smaller markers at the lower layer. The smaller markers can also have lower-layer markers nesting inside them. Each marker can be identified by its inside pattern, so the system can select a proper calibration parameter set for the marker. When the observer views the marker close-up, the lowest-layer marker will work. When the observer views the marker from a distance, the top-layer marker will work. It is also possible to utilize all visible markers in different layers simultaneously for more stable calibration. It should be noted that the Nested Marker can be used in the standard ARToolkit framework. We have developed an AR system by using a Nested Marker to demonstrate the ability of the Nested Marker. |
