Remarks

Specifies the algorithm used to find features on the calibration plate.

Cognex recommends using exhaustive (CheckerboardExhaustive) checkerboard feature finding.

Support for grid-of-dots (DotGrid) calibration plates is provided to allow for the use of existing grid-of-dots calibration plates; checkerboard plates provide more accurate calibrations. The standard (Checkerbord) feature-finding algorithm is not recommended and is retained for backwards compatibility.

If you specifiy FiducialMark, the mark type must match the feature finder. DotGridAxes is only supported for DotGrid. StandardRectangles is supported for Checkerboard, or CheckerboardExhaustive, or CheckerboardEfficient. DataMatrix and DataMatrixWithGridPitch are supported for Checkerboard, or CheckerboardExhaustive, or CheckerboardEfficient, or CheckerboardExhaustiveMultiRegion, or CheckerboardEfficientMultiRegion.
