Bead Finder Defect Detection Tool - Edge Scoring Tab
When the Edge Scoring tab is selected, the tool will display all of the detected edge candidates (which are indicated by small, color coded circles) within the region; detected edges, outlined in dark green; the location of the bead as a blue polyline; the minimum and maximum widths of the bead as yellow lines; and any found defects or gaps.
Find Edge Direction
Defines the direction in which the tool will attempt to detect edges, relative to the region (Left-to-Right, Right-to-Left, Center Outward or Outside In; default = Outside In).
Edge0 Transition
Defines the transition of the first detected edge (Dark-to-Light, Light-to-Dark or Either; default = Either). For increased accuracy and speed, specify the type of transition.
Edge1 Transition
Defines the transition of the second detected edge (Dark-to-Light, Light-to-Dark or Either; default = Either). For increased accuracy and speed, specify the type of transition.
Rule:First Edge
Defines whether or not the first edge detected receives the highest consideration when determining whether or not an edge candidate meets the criteria to be considered an edge (by default, this setting is enabled).
Rule:Strongest Edge
Defines whether or not the edge with the strongest contrast transition receives the highest consideration when determining whether or not an edge candidate meets the criteria to be considered an edge (by default, this setting is enabled).
Contrast Upper Bound
Defines the upper limit of the edge contrast transition (2 - 255; default = 255) to be considered an edge; edges with an edge contrast transition above this value will have the same highest score.
Rule:Pair Size
Defines whether or not the edge pair detected with the size closest to the Pair Size parameter receives the highest consideration when determining whether or not an edge candidate meets the criteria to be considered an edge (by default, this setting is disabled).
Pair Size
Defines the edge pair size at which the highest score is achieved (1 - 1920; default = 5). When this parameter is enabled, edge pairs detected above or below this value are scored proportionally to this value. For example, if the Pair Size is set to 10, and two edge pair candidates are detected, one with a value of 8 and another with 14, the edge pair with a value of 8 would be selected because it is closer to the limit than the second edge pair. The Rule: Pair Size parameter must be ON to enable this parameter.
Score Threshold
Defines a scoring threshold to filter out edges with scores (0 - 255; default = 10) lower than this value.
