Providing experience with registering virtual objects
into real world, applications of Augmented Reality become
more and more popular. The time performance of recognizing
and tracking markers is one key point to attract users. In this
paper, for improving the performance of recognition and
tracking of markers, QMarker, a new kind of markers is
proposed, being advantage at eliminating unwrapping marker
image when recognizing. The identifier of marker depends on
the number of circular regions on catercorners of the square
marker. Experiments show that compared with ARToolKit
markers, the speed of recognition improves greatly. In
conditions of different scale and orientation the validity of
QMarker is testified and shifting of virtual objects is also
solved.
