2. If the corresponding fiducial mark cannot be recognized correctly, teach
the position of the Reference fiducial mark at the center of the calibration
tool placed on the top surface of the ANC.
3. If the fiducial mark position teaching is performed accurately, click the
<OK> button to apply the changed value.
4. Perform calibration for Gantry 2 in the same manner.
<2. Fid Cam Scale> button
Perform calibration of the fiducial camera. There is no calibration required to
be done in advance in order to calibrate the scale (um/pixel) and rotation (deg)
of the fiducial camera. No separate jig is needed to perform the calibration.
The following is the procedure to calibrate the ‘fiducial camera scale’:
1. Click the <2. Fid Cam Scale> button in the <Calibration Menu> group.
2. If the <2. Fid Cam Scale> button is clicked, a message “Fid-Cam will
Move to Specific Fiducial Mark’s Position. Click [Next] to Move.” appears
in the message box. Click the <Next> button to move the fiducial camera
to the position for the ANC of Fiducial Mark.
3. The message “Calibration is Prepared. To Calibrate, Click [Next]” appears.
At this time, click the <Light…> button and adjust the brightness of the
light in the ‘Light Control’ dialog box so that the fiducial mark that is seen
in the ‘SMVision’ window can be seen clearly. Then click the <Next>
button.
4. The calibration is performed automatically. If it is completed, the
calibration result is displayed as shown in the following figure. Click the
<Update> button to apply the new calibration value.
The reference values for the calibration of the Fiducial Camera is as follows.
Fiducial Camera (FOV 12)
ScaleX:23.0~27.0(μm/pixel)
ScaleY: 23.0~27.0 (μm/pixel)
