Introduction
The following pages are created with the aid of a design tool to determine the optimal
camera positions and camera orientations for a special tracking task.
The paper indicates the theoretical, maximum possible tracked area. I.e. a target which
is positioned on the respective point in the tracked volume must be visible to all tracking
cameras. No person or other obscuring object may be inside the tracked area for this
test.
To design the best solution for the user, the following aspects have to be considered:
arrangements and dimensions of the projection walls,
number of users and additional persons inside the tracking volume,
tracked objects, targets and interaction devices (e.g. Flystick, glasses, fingers, hands,
knees, feet, other objects like parts of cars, etc.),
for complex applications the precise tracking task must be clear (e.g. back / palm of the
hand, fingers),
In practice the tracked area can be limited due to occlusions of users or persons inside
the tracked area:
Cam1
Cam2
Cam1
Cam2
tracked
object
In both figures the tracked objects are inside the tracking area (overlapping area
both cameras) on the same position. Left: no user occludes the target. Right: the
target is not visible to camera 1(tracking fails).
