9. Select Shape to change the fiducial type. The options are:
•Circle
• Rectangle
• Diamond
• Triangle
• Double Square
•Cross
• Video Model
NOTE
Video Model allows a unique feature to be used instead of a standard fiducial
shape.
10. Select Width to change the overall width of the fiducial.
11. Select Board/Screen Fiducial # X to change the location of the fiducial in
the X direction. The dimension is measured from the left hand side edge of
the board to the centre of the fiducial.
12. Select Board/Screen Fiducial # Y to change the location of the fiducial in
the Y direction. The dimension is measured from the front edge of the board
to the centre of the fiducial.
13. Select Contours Inner to setup the area within the fiducial to be ignored by
the vision system.
14. Select Contours Outer to setup the area outside the fiducial to be ignored
by the vision system.
15. Select Accept Score to setup the level as to whether a found fiducial should
be accepted or rejected.
16. Select Background to select whether the area surrounding the fiducial is
lighter or darker in comparison to the fiducial colour.
17. Select the Lighting tab.
18. Adjust the lighting parameters to a level whereby the fiducials just ‘white out’,
without blooming. Default level 8 on both Vertical and Oblique is usually
adequate for the majority of fiducials.
19. Select the Manual Setup tab.
20. If any changes have been made, go to Step 21. If no changes have been
made, go to Step 23.
21. Select Learn and Locate.
A figure appears on the monitor indicating the score of the fit between the
synthetic fiducial and the actual fiducial. The synthetic fiducial parameters
may need resetting and re-learning to obtain a better figure if there are other
features in the camera window.
22. Select Continue.
23. Select Locate.
24. Repeat Steps 8 to 20 for other fiducials that require setting up.
25. Select Exit.
