All Results displays the Result, Time, Pass Count, and Fail Count
information
at a glance. Expand the
inspection
tool to see
specific
results for that tool.
Midpoint
The x and y coordinates of the middle point of the found line segment.
Start Point
The x and y coordinates of the start point of the found line segment. The start point is on the end of the line segment that is
closer to the top of the ROI, when viewed in the
direction
of the arrows.
End Point
The x and y coordinates of the end point of the found line segement.
Worst Distance Point
The x and y coordinates of the farthest included point for the found line.
Worst Distance
The distance from the line to the farthest included edge point.
Length
The distance from the start point of the line segement to the end point.
Angle
The angle between the x-axis and the found line. The range is
−
180° to +180°.
Average Error
The average distance between the included edge points and the found line.
Execution
Time
The
execution
time,
in milliseconds, for the currently selected tool in the current
inspection.

Status
Status and error messages display as appropriate.
Line detect may also show another status: "Edge data may not have given a conclusive line
fit."
It is not an error and will not
directly cause the tool to fail. If this status displays and the desired line is not consistently found, adjust the tool so that fewer
edges that are not part of the desired line are found. For example, adjust the ROI to remove any uneeded area, raise the
threshold value to
find
fewer edges, or use a
specific
edge polarity rather than the generic Bright Or Dark.
8.7.4 Using the Line Detect Tool
Follow these steps for a typical Line Detect
inspection.
This example
inspection
checks whether a syringe needle is straight, bent, deformed, too short, or too long.
Note: This procedure is an example only.
1. Add a Line Detect tool to the
inspection.
2. Adjust and rotate the ROI to frame the needle. The analysis
functions
best when the ROI is
positioned
perpendicular to the
feature to be analyzed.
