camera calibration with occlusion

[asda333]

Hey

Anyone knows much about camera calibration and its implementation.

I have implemented it but am trying to find a workaround to calibrating a camera by finding corners on a checkerboard when some are occluded.

My idea was maybe i can calibrate it once to get the corners and then just display those corners even when corners are occluded but rotating the checkerboard the corners will just stay in those position because the intrinsic parameters need to be constantly updated.

I was thinking of using fiducial markers, but don't know much about it.
let alone how to implement it.

any help would be appreciated
thanks
