Default:

• 5: LineFinder、ArcFinder、BoxFinder、CornerFinder
• 20: for LineInspector, ArcInspector and Contour (When ContourMode=Arc)

Remarks
Sets the number of segments to perform edge detection in equal divisions within the search range.

By adding segments, detection becomes more robust to the change in the input image (lighting and noise). However, it takes longer detection time. Set the property according to the actual system.
