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.

Calibration Squares
Square Type Descriptions
CalibrationSquareCS100.jpg CS-100: Used to define a ground plane in a small, precise motion capture volumes.
  • Long arm: Positive z
  • Short arm: Positive x
  • Vertical offset: 11.5 mm
CalibrationSquareCS200.jpg CS-200:
  • Long arm: Positive z
  • Short arm: Positive x
  • Vertical offset: 19 mm
Calib Square.jpg CS-400: Used for general for common mocap applications. Contains knobs for adjusting the balance as well as slots for aligning with a force plate.
  • Long arm: Positive z
  • Short arm: Positive x
  • Vertical offset: 45 mm

  • Long arm: Positive z
  • Short arm: Negative x

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 1.7+

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


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:
