Main page → Calibration → Calibration Squares
During Calibration process, a calibration square is used to define global coordinate axes as well as the ground plane for the capture volume. Each calibration square has different vertical offset value. When defining the ground plane, Motive will recognize the square and ask user whether to change the value to the matching offset.
For Motive 1.7 or higher, Right-Handed Coordinate System is used as the standard, across internal and exported formats and data streams. As a result, Motive 1.7 now interprets the L-Frame differently than previous releases:
Motive 1.6 and earlier
L-Frame long (marked Z) "leg" interpreted as -Z, L-Frame short (unlabeled) leg interpreted as +X
L-Frame long (marked Z) "leg" interpreted as +Z, L-Frame short (unlabeled) leg interpreted as -X
If you wish to obtain the same coordinate system conventions as in the old releases (Motive 1.6 and earlier), you can simply rotate the L-Frame 180° around the Y-axis before setting the ground plane:
