Original Abstract

We introduce here an improved design of the Uniform
Marker Fields and an algorithm for their fast and reliable
detection. Our concept of the marker field is designed so
that it can be detected and recognized for camera pose esti-
mation: in various lighting conditions, under a severe per-
spective, while heavily occluded, and under a strong motion
blur.
Our marker field detection harnesses the fact that the
edges within the marker field meet at two vanishing points
and that the projected planar grid of squares can be defined
by a detectable mathematical formalism. The modules of
the grid are greyscale and the locations within the marker
field are defined by the edges between the modules.
The assumption that the marker field is planar allows
for a very cheap and reliable camera pose estimation in
the captured scene. The detection rates and accuracy are
slightly better compared to state-of-the-art marker-based
solutions. At the same time, and more importantly, our de-
tector of the marker field is several times faster and the re-
liable real-time detection can be thus achieved on mobile
and low-power devices. We show three targeted applica-
tions where the planarity is assured and where the presented
marker field design and detection algorithm provide a reliable and extremely fast solution.
