Mounting The Cameras; General Requirements - Art ARTTRACK Installation Manual

If in a system setup no sufficient part of the measurement volume is seen by all IR cam-
eras simultaneously, the point cloud created by the 'wand' movement has to connect all
cameras in a way that ensures the arrangement of all cameras in a common room coor-
dinate system.
: A pair of cameras is connected via a shared point cloud as long as both
Example
cameras can detect the markers of the 'wand' for a sufficient time. Additional cameras can
be connected if they form a suitable pair with the original ones. This way the calibration is
stepping forward from camera to camera.
The point cloud should fill at least two thirds of the measurement vol-
ume. Moving the wand in a restricted volume will result in reduced
accuracy of calibration or failure.

5.1.6.1 General requirements

The cameras are optimized for a predefined range of measurement volumes. System
operation in significantly smaller or larger measurement volumes can lead to reduced ac-
curacy. The measurement volume can be adjusted within certain limits simply by changing
the flash intensity of the
ware Cameras).
Major changes of the measurement volume may require different lenses and thus a new
determination of camera parameters. Please contact your
The flash intensities should not be too high. In general, a flash in-
tensity of 50-60 (3-4 for
