Cog3DCheckerboardFeatureExtractor DataMatrixTimeout Property Cognex VisionPro
The maximum time in milliseconds to search for a single DataMatrix fiducial.

Namespace: Cognex.VisionPro3D
Assembly: Cognex.VisionPro3D (in Cognex.VisionPro3D.dll) Version: 65.1.0.0
Syntax

public double DataMatrixTimeout { get; set; }

Property Value

Type: Double
The default value is 30000 (i.e. 30 seconds).
Exceptions

ExceptionCondition
ArgumentException If the supplied value is less than or equal to zero.
Remarks

This property is only used when DataMatrixTimeoutEnabled is true and LabelMode is either UseDataMatrix or UseDataMatrixWithGridPitch:

  • If Algorithm is Exhaustive or Efficient, an exception will occur if it takes longer than DataMatrixTimeout to find an acceptable DataMatrix fiducial.
  • If Algorithm is ExhaustiveMultiRegion or EfficientMultiRegion, an exception will occur if it takes longer than DataMatrixTimeout to find the first acceptable DataMatrix fiducial. Once the operator finds the first acceptable DataMatrix fiducial without timeout, the operator processes each isolated region of checkerboard features. For each isolated region of checkerboard features, if it takes longer than DataMatrixTimeout to find a DataMatrix fiducial, the operator will not include any features from that region but no exception will be thrown.
