When you enter the actual coordinates of the position that results from searching for a registered model, the
calibration parameters are calculated automatically. (The position resulting from the search is found at the
subpixel level.)

Description
These are the calibration conversion values.
These values are used to convert the Camera coordinates to the actual coordinates.
The following formulas are used to convert to actual coordinates.
• (X,Y): Camera coordinates of measurement position, Unit: pixels
• (X',Y'): Converted coordinates (actual coordinates)
X' = A × X + B × Y + C
Y' = D × X + E × Y + F
Same Magnification in X and Y Directions
Different Magnifications in X and Y Directions
Measure two positions and enter the actual coordinates of them.
Measure three positions and enter the actual coordinates of them.
