Pattern Recognition (XDLM 237)
Replay at Pos.No. If the specimen has repetitive structures (e.g. a panel with sev-
eral individual printed circuit boards), then you can use this to
define the position at which the pattern recognition is to start
again from the beginning.
Max. rotation If the measuring item is arranged so that it is skewed in rela-
tion to the defined search item (e.g. due to skewed posi-
tioning), then the measuring item can still be detected. Enter
the maximum expected rotation angle here; it should not be
larger than necessary though, because this increases the cal-
culation time.
Previous angle Setting: If you have measuring items with sev-
eral measuring positions that could have a skewed position.
Set the angle for the first measuring point, e.g. +/- 120
degrees, and
Previous angle for the other measuring points.
This saves calculation time.
Angle= Shows the actual rotation angle that was found; see also
Max. Rotation .
Pattern definition
Total video area When activated, the search item is searched for in the entire
video image.
Show search item Shows the search item (the image that is to recognized). Acti-
vate this option to define the search item.
Show search area Shows the search area (the area of the video image in which
the search item is searched for). Activate this option to define
the search area.
Show cross hair Shows the crosshairs of the video image.
Saved pictures Deletes the current reference image with the corresponding
parameters or all reference images and all parameters.
Clear current
Clear all pict.
Correction / X / Y When the found position is not exactly in the crosshairs, you
can correct it here. Entry in pixels. The correction has a global
effect on the instrument and not just the product.
