CogCalibNPointToNPoint ComputedRMSError Property Cognex VisionPro 9.5
Returns the root mean squared error between the uncalibrated points and the mapped raw calibrated points, expressed in uncalibrated space. It is valid if the computed uncalibrated from raw calibrated transform exists. Otherwise, zero is returned.

Property Value

Type: Double
Remarks

Returns the root mean squared (RMS) error between the uncalibrated points and the mapped raw calibrated points, expressed in uncalibrated space. The RMS error value is valid if the computed uncalibrated from raw calibrated transform exists. Otherwise, this method returns zero.

The mapped raw calibrated points are calculated by applying the UncalibratedFromRawCalibrated transform to the raw calibrated points. If the Calibrated property is True, this transform, which is the result of calling Calibrate , is always non-null. However, it may also be non-null if Calibrated is False. For example, if you calibrate and then change only the RawCalibratedFromCalibrated transform, the UncalibratedFromRawCalibrated transform remains unaffected, even though Calibrated is now set to False.

Default Value: 0
