CogBeadInspectDefect LeftStepMax Property Cognex VisionPro 9.8 SR1
Get the maximum step value measured by the calipers of this defect along the left edge of the bead. This measurement can help you to identify sharp fluctuations in the position of the edge.

public double LeftStepMax { get; }

Property Value

Type: Double
The largest step value along the left edge of the bead.
Remarks

A "step" measures the largest relative deviation in the edge of the bead path when moving from a caliper to either of its neighbors. The deviation is measured sideways -- perpendicular to the direction of the bead path -- and is expressed as a fraction of the average bead width trained at that caliper's location. For example, a step of 0.1 indicates that the edge of the bead path moves sideways by 10% of the trained width at that location. This measurement helps to quantify the smoothness of the bead edge.

The left and right edges of the bead are defined relative to the direction of the bead path. If you imagine that you are travelling along the path, from its start to its end, the left edge will be on your left-hand side. The right edge will be on your right-hand side.

If the user disables StepThresholdEnabled, the bead step will not be measured at run-time and GetCaliperLeftStep(Int32), GetCaliperRightStep(Int32), LeftStepMax and RightStepMax will all be reported as zero.
