Do we need to know the transform between different patterns?

Thanks for the work. The question is as the title.
Another following up is if one camera needs to visualize all the patterns? Can one camera just visualize one pattern or even part of one pattern for calibration?

Currently it will only work if there is overlap between patterns (in at least some of the views). It will calibrate the transform between those patterns. There is a method to initialise the calibration for non-overlapping patterns (e.g. two cameras viewing different patterns facing in opposite directions), it's just that I haven't implemented it. The key is to use a hand-eye calibration procedure on the estimated board poses. I've even wrapped the OpenCV code for this - just haven't done the code for the initialisation! Cheers, Oliver
