Fiduciary Markers
A fiduciary marker is an object used as a point of reference to measure angle and
distance for augmented reality. These are often referred to simply as “markers.”
maxReality utilizes two series of markers. Markers “s0” to “s61” are referred to as
“Static” markers and “m0” to “m62” are known as “Moveable” markers. Static
Markers are a single relational group used to reference the position and orientation of
the user in the real world. Marker “s0” is used to define the origin for this group and
the others provide relative positioning or tracking. Moveable markers are
independent of each other.
Note: The vertical bar, shown in red in the above illustration, is called the “Marker Key”. The Marker
Key is used to establish the orientation of the marker.
Static Markers
Static Markers, numbered “s0” to “s63”, are used to form Marker Patterns that
enable tracking and stable positioning even when the base marker “s0” is not in visual
range for the Wrap AR cameras.
Marker “s0” is the default or base marker and the others 63 static markers are used to
reference its relative position. By learning the relative position of each static marker
to the preceding marker the in the origin marker’s (s0) position can be calculated
even when it may not be currently in the visual range of the cameras.
