3D calibration object

[Oguked]

Are 3D calibration objects supported? In the TODO section you wrote “Add ability to calibrate with cameras which have no overlap (using hand-eye AX = ZB initialization method)”. Does that mean I cannot calibrate my cameras with e.g. a calibration cube like shown in the Calico paper? I have a use case where the cameras have very large angles relative to each other. That means, that I cannot use a simple board-based calibration object and need a 3D calibration object. Does your implementation support that?

Not at the moment, it's in the TODO but likely I won't have time to work on this any time soon! In principle it's not a lot of work but there's always quite a bit of debugging/verification required etc.

The hand-eye calibration routines needed to initialise the no-overlap case is all present in OpenCV.
