Steps for Fiducial Setup

9. Background refers to the average grayscale level in between " Template" and Outer Radius. Normally this

area should be dark and thus it should be set between 50-100.

10. Middle refers to the average grayscale level in between "Outer Radius" and "inner Radius". Normally this

area should consist of dark and bright area and thus it should be set in between 100-200.

11. Foreground refers to the average grayscale level inside the "Inner Radius". In case if "Inner DC" is used,

then foreground refers to the average grayscale level in between the inner radius and inner DC. Normally

this area is bright, thus it should be set in between 200-250.

12. Inspect and observe the value obtained in Current Inspection Value. The above parameter should be set

appropriately in order to get the highest score for "Current Inspection Value".

13. Current Inspection Value, ensure that an appropriate Presence Threshold is set. Presence threshold

should not be set too loose (typically 700).

14. Custom Lighting custom_#no.txt stores the lighting setting information. User may change the lighting

configuration in the file.

15. Alternate fiducial can be set when necessary (eg. When there is different fiducial sizes or shapes)
