For existing calibration files, without calibrating the entire motion capture system (i.e., without performing T-shaped calibration), you can perform L-shaped calibration individually to update the coordinate system origin. After the calibration is complete, the original position of the coordinate system origin in the 3D view will be updated.
Before calibrating the origin, please determine the new origin position. Place the L-shaped calibration rod in the motion capture area. In the 2D view, at least 25% of the cameras should be able to completely capture all four marker points on the L-shaped rod. There should not be any noise points in the 2D view except for the four marker points on the L-shaped rod.
Open the calibration panel, select "Origin Calibration, " click on the gear icon to open calibration settings, and set the type of L-bar used for this origin calibration. Do not modify the "Calibration Axis"(8.4.1);
Close the origin calibration settings and click the "Origin Calibration" button at the bottom of the calibration panel. After calibration is completed, click the "Finish" button and save the calibration file separately. If you need to recalibrate, click the "Reset Calibration" button.
Refer to the L calibration steps in section "VIII. (ii) Basic Calibration" of this manual.
Switch to the 3D view; the origin position will update to the location where the L-bar is placed.
