Opencv use CalibrateCamera calibrating camera, or use slovePnP posture,
In calculating out translation matrix T,
X, Y is the distance between relative to what point, where is the origin, is the first point on the calibration board, or left upper corner of the screen, or CCD on the upper left corner?
Where is the Z plane? T the z distance which plane to which plane? The CCD? The lens front end? The lens back end? See the data where all don't like too for
