Click on the Vision page icon.
3. Click Calibration.
4.
Make
a note of the current 2D and
3D calibration values for before-
and-after calibration comparisons.

Step 5
1.
Click on the tip of the inverted
triange of the 2D target to centre
the FOV.
2.
At the Lighting Box
menu, adjust
the Back light if necessary. 15 is
default. A value of 10 to 20 is
good to use. There should be

Adjust to value 50~60.
The machine takes about 40s to
adjust the Side 1 and Side 2
lighting. The fringe pattern in the
FOV will disappear, this is OK.
a. When perform 2D calibration,
user can zoom in the image to
check if the lighting is too
bright and the image
saturated.
b. As you can see from image
below, the corners should be
connected and the “White
regions” are not totally white
but have lower gray level

Check the calibration results:
● Both Resolution X and Y
should be between 3.6788
and 3.7532 µm/pixel inclusive
(3.716µm ± 1%).
● Camera Rotation should be
between -0.5° to 0.5°
inclusive
(±0.5°).
