Optical axis is moved by a half-pixel #2

Hi,

Thank you for this code and dataset release! This is not a real issue but a comment that might be useful to other users.

So as to use your calibration, I had to move the optical center by a half pixel in each direction so that the projection of the mesh perfectly fits the image mask: cx=314.5 cy=241.5

Best!

Hi there, thanks for the interest in the dataset. Could you provide some examples where this 0.5 pixel shift helps? A before/after comparison would help.
