Uniform Marker Fields: Camera Localization By Orientable De Bruijn Tori

Popis výsledku v původním jazyce

In various applications, a wider area needs to be covered by fiduciary markers but a large marker cannot be used because only a fraction of the area is to be viewed by the camera. Such an area can be covered by a number of small markers with unique identifiers. However, with the camera freely moving in the scene and with occluders present, it is difficult to ensure that at least one of the individual markers is completely visible, unless the markers are small and numerous. In that case, the markers arenot recognizable from larger distances. In this paper we introduce the concept of Marker Fields which overcome this limitation. The Marker Field covers a large-scale planar (or non-planar) area and it is composed of mutually overlapping partial markers.We propose a particular arrangement of the Marker Field: a Uniform Checker-Board Marker Field, which is a black-and-white checkerboard whose square modules are defined by aperiodic 4-orientable binary (n,n)-window arrays (De Bruijn tori).
