Noise Level The amount of background noise present in the image. Higher noise
means the edges must be farther apart. Lower noise allows edges that
are closer together.
Maximum Number
of Edges to Find
Limits the number of edges found to those with the strongest transition
Edge Pattern The edge pattern to find (Rising indicates a transition from dark to light;
Falling indicates a transition from light to dark)
Subpixel Method Indicates how many subpixel points to average when finding the edge
points. More points used provides greater accuracy but takes more time.
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 Wide Line ROI. Allows multiple measurements that occur
at regular intervals across the image with one tool.
Step Distance The distance between the measurement steps
Step Angle in
Degrees
The step angle relative to the Wide Line 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. (See “Scale Factor” on page 3-125.)
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. (See “Scale Factor” on page 3-
125.)
Scale Factor List The list of Scale Factors used when Number of Steps is greater than
one. (See “Scale Factor” on page 3-125.)
Scale Factor Train
Distance List
The list of Scale Factor Train Distances used when Number of Steps is
greater than one. (See “Scale Factor” on page 3-125.)
