5.1 Setting up the cameras

5.1.1 Camera orientation

While mounting the cameras or
of each camera and the
volume is covered completely by the field of view (FoV) of all cameras.
On the one hand camera mounting has to ensure that tracking is possible over the entire
measurement volume. On the other hand attention has to be paid to the fact that the
calibration angle (for room calibration) can be seen completely by at least two cameras
or the SMARTTRACK2/3/M
has to overlap sufficiently to enable the calculation of the photogrammetric orientation of
all cameras in a common coordinate system, especially if the calibration angle can not be
seen by each camera.
Furthermore it is important to remove disturbing reflections (refer to 5.1.2 on page 40)
from the FoV of cameras and
important to minimize mutual blinding of the cameras, i.e. the IR flash of one camera is
inside the FoV of another(refer to 5.1.3 on page 41).
Therefore, as part of its GUI
2-dimensional graphical display or monitor for each camera equivalent to its field of view.
At this point, you will probably find it most useful to become acquainted with the graphical
user interface and the main window of
Guide for detailed information.
5.1.2 Localizing and removing of disturbing reflections
Possible sources of disturbing reflections may be diverse. Still all of them may be detected
when starting the Monitor 2DOF display
as markers, i.e. with small coloured crosses or circles, depending on the distance to the
camera or SMARTTRACK2/3/M
Typically the reflections arise from one (or more) of the following points:
active or passive targets that are inside the FoV / tracking range of the cameras,
strong IR sources (e.g. sunlight or sunrays, halogen lamps, ...),
