I have the same issue. The sync calibration fails silently, the calib_pose.yaml is being created but extrinsics matrices are empty (i.e. rows: 0; cols: 0, data: []).

@yaozipeng could you make some progress on this issue?
Also I am using the OpenCV4 version of this repo (see here) - not sure if it might be related to that? Which version are you using?
