A Calculation value
These are calibration conversion values. Camera coordi
nates are converted
to actual coordinates based on these values. The conversion formulas for
actual coordinates are as follows:
• (X, Y): Measurement point (camera coordi
nates), Unit: pix
• (X', Y'): Conversion point (actual coordinates)
X'=A ×
X + B × Y
+ C
Y'=D × X + E × Y + F
