When I run: rosrun kinect2_calibration kinect2_calibration chess5x7x0.03 calibrate sync, it displays [INFO] [CameraCalibration::calibrateExtrinsics] re-projection error: 6.92399e-310 [INFO] [CameraCalibration::calibrateExtrinsics] Rotation: [] [INFO] [CameraCalibration::calibrateExtrinsics] Translation: [] [INFO] [CameraCalibration::calibrateExtrinsics] Essential: [] [INFO] [CameraCalibration::calibrateExtrinsics] Fundamental: []

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?
