Tolerance
■ Select [Tolerance]
For spot-type badmarks:
The value set here determines what percentage of the badmark surface may be
missing in the rectangle defined in
[Smallest Enclosing Rectangle] to be still
considered as a badmark.

NOTE: Settings depend on the physical properties of the badmark. Badmarks
indicated by means of a felt pen require a higher tolerance than badmarks
indicated by means of a sticker.
For fiducial-type badmarks:
The value set here determines how much (in percentage) the area of a detected
badmark may differ from the area which is specified in the teach data
(see FIGURE 6 -13).
That area is defined by the
[Area of Fiducial] parameter, and limited by the
[Smallest Enclosing Rectangle] setting.

NOTE: Common settings range from 10 to 15% on
physically good badmarks; badmarks of a lesser quality may require higher
settings.

Light Level and Threshold
For spot-type badmarks:
■ Select
[Light Level and Threshold]
For a reliable badmark detection, the light level and threshold must have been set.
The threshold value is used by the binary algorithm to transform a grey level image
into a black & white image. The threshold value is used by the interpolation
algorithm to analyze grey level transitions in the image. For more information see
the Vision General Manual, ordering number 5322 871 69201.
