To make it easier for you to assess the range of brightness or the contrast, these gray-scale values
have been converted with the help of transformation tables into color as is shown below: 6
NOTE 6
In order to achieve a good uniqueness value the contrast difference between the fiducial and its
surroundings should be at least 75. For example, if the background is green the fiducial should be
orange. 6
If the contrast is unsatisfactory you can select in the menu between five pre-programmed trans-
formation tables in order to obtain a color image which is capable of supplying the necessary in-
formation. In addition, you can also program a transformation table yourself. 6
NOTE 6
When the color presentation is changed the fiducial will be taught at the same time. 6
