A to F represent the calibration conversion values. The camera
coordinates are converted to physical coordinates based on these
calibration conversion values. The formulae for conversion to
physical coordinates are as follows:
X' = A × X + B × Y + C
Y' = D × X + E × Y + F
(X,Y): measurement position (camera coordinates), unit: pixels
(X',Y'): conversion position (physical coordinates), units: mm
The physical unit for X direction on the screen
