[question] marker size #184

Describe the problem I get the idea from this page that the marker shall be proportional to u / f, which I think is the upper left entry of the intrinsic matrix? Thanks for answering in advance.

it's a rule of thumb. f is the focal length, so yes the first element of the calibration matrix.
