Performance Motion Box
While each component of the laserBIRD is
manufactured within very tight tolerances, it
is almost impossible to construct a system
that matches the theoretical model perfectly.
For this reason, all systems are subjected to a
calibration procedure that optimizes
performance over a given region. This
region is referred to as the Performance
Motion Box.
Figure 3.7: Performance Motion Box:
Top view (left) and side view (right)
Dimensions in each axis are:
X: +17" to +39" (+43 cm to +99 cm)
Y: -9" to +9" (-23 cm to +23)
Z: -12" to +12" (-30cm to +30cm)
Applications requiring high accuracy should restrict sensor motion to locations within the
Performance Motion Box. Tracking outside this box may not yield results with equivalent
accuracy.
