how to calibrate two cameras placed up and down?
I want to calibrate two cameras which are placed up and down, but if I used the 'rectifyStereoImages' function, I got this result. I want to know if there are differences between camera calibration of cameras placed with two positions: (1)up and down (2)left and right. The calibration result is showed in the last picture.
what does "up and down" mean?
