Tracking Cameras
To avoid measurement problems, no light sources or highly reflecting areas should be
visible to the camera. Especially strong point light sources like e.g. halogen lamps and
direct or reflected sunlight may imply problems for the measurement (fluorescent lamps
are ok).
Please install the cables such that
•
no one can stumble over the cords,
• the cords cannot be damaged,
•
the cords cannot damage the cameras due to mechanical strain,
•
the line of sight of the cameras is not obstructed.
Inappropriate cabling may pose a serious hazard to health and safety.
Cable ducts or fixings should be used and a strain relief should be
installed!
Please refer to chapter 5.2 on page 60 for more information.
4.6 TRACKPACK (discontinued)
Keep a distance of min. 20 cm when operating the camera ! The
camera is assigned to the Exempt Group according to IEC62471-1 and
therefore poses no risk or hazard to the human eye or skin at this dis-
tance.
Description The TRACKPACK is a two or four camera infrared optical tracking system
for use in medium-sized working volumes. It is the best solution for Head- and Flystick-
tracking in multi-sided projection environments (max. 3 m x 3 m x 2 m), or in front of
medium-sized projection screens (up to 4.5 m wide). The system consists of two or four
TRACKPACK cameras and a TRACKPACK Controller.
By default the TRACKPACK is equipped with a 3.5 mm lens. Depending on the applica-
tion and the setup the TRACKPACK camera can be equipped with other lenses (i.e. with
different focal lengths). Refer to A.1 on page 236 for a list of available focal lengths and
the respective FoV.
The RJ45 connection between TRACKPACK camera and controller is
used for power supply and synchronization signal. It is not a standard
Ethernet connection! That is why connecting the RJ45 connector to
any other than the equivalent port of the controller may damage the
camera or the connected partner.
