Subpixel Method The type of subpixel averaging. The grey levels of adjacent pixels (3, 5,
or 7) around an edge point are averaged and used to interpolate the
edge to a fraction of a pixel. See “Subpixel Method” on page 3-125.
Subpixel Position The subpixel position for edges that are not well defined. See “Subpixel
Position” on page 3-144.
Subpixel Search
Distance in Pixels
The maximum distance, in pixels, that the subpixel algorithm will search
from the threshold edge for the subpixel edge. See “Subpixel Search
Distance” on page 3-125.
Number of Steps Duplicates the primary ROI. Allows multiple measurements with one
tool.
Step Distance The distance between the measurement steps
Step Angle in
Degrees
The angle of the secondary ROIs from the primary ROI (see “Step
Angle” on page 3-125)
Scale Factor The scale factor applied to the output distance. This is applied after any
camera calibration.
Scale Factor Train
Distance
When the tool is trained, this scale factor is calculated so that the mea-
sured distance is scaled to this value.

one.
