Can't compute the transformation from the base frame to the world frame

[PhiAbs]

I am trying to calibrate a realsense camera using the easy_handeye package. I track some ar markers with the ar_track_alvar package. I want to do a eye on base calibration. Using the GUI from the easy_handeye package, I managed to take samples. The transformations are shown in the "samples" window and they are correct. However, if I want to compute the transformation between the world frame and the camera, the transformation shown in the "Result" window is always the following:

translation:
x: 0.0
y: 0.0
z: 0.0
rotation:
x: 0.0
y: 0.0
z: 0.0
w: 1.0

For the frames I used the following.
Tracking Base Frame: The camera frame
Tracking marker Frame: The frame of the tracked markers, in the camera system
Robot Base Frame: The world frame
Robot Effector Frame: The robot gripper frame which holds the ar markers

Does anyone know what the issue is or what I did wrong?

Hi @PhiAbs,

could you please post the collected samples?

This package uses ViSP as a backend. Have you tried using it directly, passing the samples collected with easy_handeye? If the result is then correct, we have a problem passing it the results or fetching back the result.
