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.

Coordinate System

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

Motive 1.6 L-Frame


Motive 1.7+

L-Frame long (marked Z) "leg" interpreted as +Z, L-Frame short (unlabeled) leg interpreted as -X

Motive 1.7 L-Frame




The simplest method to account for this change is to rotate the L-Frame 180° during calibration (rotating "around the Y axis"). If the L-Frame is not rotated during calibration, Motive will display inverted global coordinates when comparing the same data in Motive 1.7 and Motive 1.6 and earlier:
