surface of the ANC. The size of the fiducial mark of the calibration tool is 1.6 mm.
3. If the fiducial mark position teaching is performed accurately, click the <Update>
button to apply the changed value.
4. Perform calibration for Gantry 2 in the same manner.

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.
The following shows how to calibrate the fiducial camera scale manually. If the
<Automatic Next> check box has been selected, the next step is performed
automatically.
1.Click the <2. Ref. Fid. Camera Scale> button in the <Calibration Menu> group.
2.If the <2. Ref. Fid. Camera Scale> button is clicked, a message “Set calibration tool
to the specific tool’s position on ANC. Click [Next] to Move.” appears in the
message box. Next place the calibration tool at the position for the front ANC
calibration tool and click the <Next> button to move the fiducial camera to this
position.
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.

displayed as shown in the following figure. Click the <Update> button to apply
the new calibration value.

Memo The reference values for the calibration of the Fiducial Camera is as
follows.
ScaleX: 23.0 ~ 27.0(m/pixel)
ScaleY: 23.0 ~ 27.0 (m/pixel)
ScaleR: -2.0 ~ 2.0 (deg)
18.3.4. Common XY Calibration
A process to coincide the coordinates of two Gantries. If it is not done correctly, there will
be an offset between Gantry 1 and Gantry2, which will not only affect placement precision
but also cause collision of gantries.

<Automatic Next> check box
Select this check box and click the <Next> button. Then the process that matches the
coordinate systems between gantries is performed automatically.
<Manual> check box
Move the gantry to the designated position by using the teaching box and perform the
process that matches the coordinate systems between gantries manually.
<Test only> check box
When calibration is done after selecting this, the result is displayed but not saved.
Consequently, it is possible to check the changes made in the current machine compare
to the previous data.
