If you see only two markers at a time, how can you know anything about their relative position? Even if you learn something about their relative position, do you learn anything more than a distance? How do you estimate the angle between the first second and third points if you never see them together?

I don't have any experience in this kind of thing, but it sounds like you don't have enough information to reconstruct anything.

I will know the scale and orientation of each marker as well, each marker is a regular square with the same area size so I can estimate its pose relative to the camera and place it in 3D space. I can extract the 3D transformation between the markers from this.

Oh, I see. I thought markers were effectively points. Thanks for the explanation. And sorry I don't have anything valuable to contribute.
