CogBeadInspectRunParams.StepThreshold Property

CogBeadInspectRunParams StepThreshold Property

Cognex VisionPro 9.7

Gets or sets the maximum relative amount an edge position can deviate from neighboring edges. It is specified as a fraction of average bead width at that location. A low value means a closer match and a high value means more tolerance.

Remarks

This property only supports float value type precision; up to 5 decimal places (such as 0.00001) can typically be expected to be maintained. Further precision can be assigned but will be lost (truncated).

The average bead width is computed at train time. It averages the bead width from a number of calipers. The number of calipers is specified by the SmoothingFactor train property.
