menu, options
NOTE:
Buttons are active when the text on the button is black (rather than gray). This means that you can launch the
associated function by clicking on the button with the mouse.
The Search area button will, for example, only be active if you have
– already loaded a fiducial or
– created a new fiducial.
A model must already exist for the selected fiducial.

If a new fiducial number has been input then you can select the
Standard values
options. If you have loaded
an existing fiducial all options will be accessible. In the menu the following options will be available:
– Changing the parameters of the fiducial structure fields (template)
– Changing the parameters of the search area
– Teaching with standard values
Fiducial structure field parameters are
– width,
– height and
– camera resolution
Search area parameters are
– width and
– height
The parameters are stored in a list in the station computer. This list is initialized with default and current values
when the
Load fiducial
option is launched.
If you change a parameter, a teach command will be generated in the machine controller (MC). The only
parameter block which will be added to the teach command in the general parameters will be the block which
has been changed.
For this reason the machine controller generates three different teach commands:
– Teach with standard values
– Teach the search area
– Teach the fiducial structure field (template)
5.5.4.1
Standard Values
Option
When this option is selected
– the menu is closed.
– the teaching process is launched.
– the video image is shown with fiducial, fiducial structure field and uniqueness value.
– header and footer with commentary, measurement results, key assignments and command sequences will
be displayed.
The teaching process will now be launched with the standard values. The result of the teaching process is the
uniqueness value which is shown in the header of the video image. This value provides information on the dif-
ferentiation quality of the fiducial with respect to other structures in the vicinity of the fiducial. The figure dis-
played may range between
0 = unsatisfactory and
100 = very good differentiation capability.
Practice shows that a uniqueness value of at least 60 must be achieved for fiducials and ink dots.
