TRACKPACK

Figure 4.9: Camera TRACKPACK
Mounting The TRACKPACK cameras are optimized for a predefined range of measure-
ment volumes. System operation in smaller or bigger measurement volumes can lead to
reduced accuracy. The measurement volume can be adjusted within certain limits simply
by changing the flash intensity of the
ART infrared cameras (see chapter 8.5.1 on page
146).
i
The flash intensities should not be too high. In general, a flash inten-
sity of 3-4 might be sufficient.
Major changes of the measurement volume may require different lenses and thus a new
determination of camera parameters. These changes have to be done at the
ART labs.
Be aware that a tracking system is very sensitive to camera movements. Therefore the
cameras have to be mounted in a way that camera movements (especially vibrations) are
reduced as much as possible.
Z
Mounting on tripods may be sufficient for presentations and prelimi-
nary installations, but is not recommended as a permanent solution!
If you want to mount the camera on a tripod just mount the carrier on the bottom of the
camera.
The carrier for the TRACKPACK can be attached on both bottom and top side of the
camera. Attach the carrier with the T-piece pointing to the back of the camera in a similar
way to figure 4.2 on page 30. Note, the ceiling suspension is already connected to the
carrier in figure 4.2.
