Rough Min Distance: The distance between the edge point and the fitted straight line. If
the distance is greater than the threshold, it is determined as the defect point to be filtered.
If the Defect Size Enable or Defect Area Enable is enabled, you need to further filter
according to the corresponding threshold.
Defect Size Enable: If enabled, you need to enter Rough Min Size.
Defect Area Enable: If enabled, you need to enter Rough Min Area.
Arc-Pair Defect Detection
The tool of arc-pair defect detection is used to detect the concave-convex and fracture part of the
arc pair. By setting the width eligibility range, defect size, and defect area, this tool searches the
defect area between two arcs and outputs related information. 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.
Edge 0 Polarity: It includes Dark to Light, Light to Dark, and Both.
Edge 1 Polarity: It includes Dark to Light, Light to Dark, and Both.
Filter Kernel Size: It is used to enhance the edge and suppress noise, and its min. value is
1. When the edge is blurred or there is noise interference, you can increase its value to make
the detection result more stable. If the distance between the edge and the edge is smaller
than the filter size, it will affect the accuracy of the edge location or even lose edge. This
parameter value needs to be set based on the actual situation.
Contrast Threshold: It is also called gradient threshold, and its range is from 0 to 255. The
edge point whose gradient threshold is larger than this value can be detected. The larger the
