How the Line Find tool works
This tool can find a line by locating multiple points on an edge and fitting them; find two lines and report the
center line between them; and pass or fail based on the length, angle, straightness error (average fitting
error), and maximum gap length of the found line. It can only find one line or one pair of leading and trailing
lines.
Max Straightness
Error
The maximum deviation allowed from a straight line (0 indicates a
straight line)
Output Name What it is
Passed If True, the found line’s parameters lie within all the limits
Line Segment The found line
Output Origin Rela-
tive to Tool
The X and Y coordinates of the center point and the angle of the found
line relative to the Tool Origin.
Output Origin Rela-
tive To RWC
The X and Y coordinates of the center point and the angle of the found
line relative to the entire image space.
Edge Points The points used to create the found line
Outlier Points The points further from the found line than the Outlier Distance Thresh-
old
Greatest Outlier
Distance
The distance of the furthest Outlier Point from the found line
Gap Segments Line segments of gaps longer than the Max Gap Length
Greatest Gap
Length
The length of the longest gap
Straightness Error The deviation of the found line from a straight line (0 indicates a straight
line)
