Camera Calibration
These are calibration conversion values. Camera coordinates are converted to actual
coordinates based on these values. The conversion formulas for actual coordinates are as
follows:
(X, Y): Measurement point (camera coordinates), Unit: pix
(X', Y'): Conversion point (actual coordinates)
X' = A × X + B × Y + C
Y' = D × X + E × Y + F
Magnification ratio for the X axis in the coordinate system after calibration
Magnification ratio for the Y axis in the coordinate system after calibration
The origin X position in the coordinate system after calibration
The origin Y position in the coordinate system after calibration
The X axis angle in the coordinate system after calibration
The Y axis angle in the coordinate system after calibration
Angle created by the X and Y axes in the coordinate system after calibration.
