Optitrack calibration

back to ASTA motion capture

Calibration scale results

The test moves a marker a distance of 1.5m and this should be the distance Optitrack should show. The system is just calibrated, there is perfect coverage.

The first position of the test marker.

Optitrack reference detection

The end position of the test marker after movement of 1500mm.

Optitrack distance measurement of the 1500mm movement.

The actual movement starts at about 0.3mm and ends at 1500.6mm - a distance of 1500.3mm with an accuracy of less than 0.5mm.

The optitrack say 1503.97mm a scale error of about 0.3%

May be a problem with the calibration wand.
