When you pick the button to exit the Feature Locations panel, the
“learned” data appear in the Nominal field and indicate, from left to right, an
X coordinate, a Y coordinate, and an angle (
q).
NOTE: If the warning message shown in Figure 6.41 appears after you pick
the
Nominal field, it indicates a problem with some aspect of the feature
configuration. Pick the button to exit this message.
Figure 6.41 Warning Message: One or More Features Not Found
If one feature is active (Feature A or Feature B), the “learned” X and Y
coordinates in the
Nominal field identify the location of the center of the
single feature window. Since no angular measurement is involved in this
case, the angle (
q) is always 0.0°.
If two features are active (Feature A and Feature B), the “learned” X and Y
coordinates in the
Nominal field identify the location of the midpoint on a
line connecting the centers of the two feature windows. The angle (
q)
indicates the relation of that line to the X–axis of the image field.
