Grid Pattern, After Calibration
NOTE: If you get an error message that there were an insufficient number of cal-
ibration dots found, your dot target is probably not sharp enough. It takes only 9
dots to calibrate. Try adjusting the Edge Sensitivity, so the calibration will find more
dots.
For very small fields-of-view, it may be difficult to calibrate a camera if the dot grid is
not high quality. Modifying the Outline Level may allow calibration in such cases, even
with less-than-perfect dot grids.
If a dot is found that is less than one-half the average dot size, or greater than one and
one-half the average dot size, the dot will be displayed in orange, to indicate that the
calibration may be picking up artifacts within a dot, or outside of a dot. If this occurs,
you need to adjust the Edge Sensitivity, lighting, or quality of the dot grid you are
using.
