Property Documentation

◆ PixelSize

double PixelSize

get

Pixel size after transformation.

The pixel size has the same units as referenceDistanceCalibrationPoints and referenceWidthStripes given within function CalibrationLineScan.CreateLineScanCalibration.

◆ Transformation

NonLinearTransformation Transformation

get

Transformation object.

The transformation object includes the coefficients of a 3rd order polynomial. Mixed coefficients are zero. Depending on the ScanDirection specified in LineScanCalibrationConfiguration, the estimated polynomial is:

Scan direction in X:

x' = a1 * x^3 + a5 * x^2 + a8 * x + a10

y' = b9 * y

Scan direction in Y:

y' = b4 * y^3 + b7 * y^2 + b9 * y + b10

x' = a8 * x

where

x: pixel position in x (column),

y: pixel position in y (row),

a1-a10: coefficients in x,

b1-b10: coefficients in y,

x' and y': transformed x and y coordinates.
