CogOCVPattern.CharacterScalingUncertainty Property

CogOCVPattern CharacterScalingUncertainty Property

Cognex VisionPro

A common scaling uncertainty for any character position that has its UsePatternCharacterUncertainties set to true. The scaling uncertainty specifies the expected image-to-image variation of a character's scale. This is an unsigned value.

Remarks

Scaling uncertainty specifies the expected +/- range of the of the image-to-image variation of any character's scaling factor. This is an unsigned value; supply a value of 0.05 to specify a range of scale factors from 0.95*Scaling through 1.05 *Scaling. This value is applied to any character position that has UsePatternCharacterUncertainties set to true.

Default Value: 0.0
