value, the stronger noise resistibility, the smaller the number of edges obtained, and even
the target edge points are filtered out.
Ideal Width: It refers to the ideal distance between inner and outer arcs.
Caliper Height: It refers to the height of caliper.
Caliper Length: It refers to the length of caliper.
Caliper Spacing: It refers to the spacing of caliper.
Width Eligibility Range: This parameter is the main parameter for the detection of arc pair
defects. Only the arc pair width within this parameter range is considered as a eligible.
Defect Size Enable: If enabled, you need to enter Rough Min Size.
Defect Area Enable: If enabled, you need to enter Rough Min Area.
Caliper Number: It is used to scan the ROI area quantity in edge points.
Reject Number: The minimum number of points whose error is too large to be excluded
from fitting. In general, the more outliers, the larger the value should be set. In order to
obtain a better search effect, it is recommended to use it in conjunction with the elimination
distance
Threshold to Remove: The maximum pixel distance between the outlier and the fitting
circle is allowed. The smaller the value, the more points will be excluded.
Angle Tolerance: The maximum angle is allowed.
Track Tolerance: The maximum pixel offset is allowed by edge tracking.
Line-Pair Defect Detection
The tool of line-pair defect detection is used to detect defects between a pair of straight lines that
are deformed or broken, and output the corresponding defect information. It can be used to detect
the deformation and defects of the edges of rectangular work pieces, determine the regularity of the
work piece edges, and search small burrs and dirt. The specific operation method is shown below.
See Arc Edge Defect Detection for other parameters.

Edge Search Type
It includes Widest Edge Pair, Nearest Edge Pair, and Strongest & Nearest Edge Pair.
