CogCalibFeatureExtractorCheckerboard.PrecisionThreshold Property

CogCalibFeatureExtractorCheckerboard PrecisionThreshold Property

Cognex VisionPro 9.24

Gets/sets the threshold for discarding vertices with excessive positional uncertainty. This is specified in pixels.

Namespace: Cognex.VisionPro.CalibFix

Property Value

Type: Double
The default value is HUGE_VAL (the largest representable value of type double).

Events

Event Type	Reason
ICogChangedEvent Changed	Fires when this property changes.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	If the input value is less than 0 in the setter.

Remarks

Due to noise and distortion, there are errors in the computed vertex positions. The algorithm internally estimates the position uncertainty for all found vertices, and excludes those from the final result whose position uncertainty estimates exceed the threshold specified here.
