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: \r\n\r\ntranslation: \r\n  x: 0.0\r\n  y: 0.0\r\n  z: 0.0\r\nrotation: \r\n  x: 0.0\r\n  y: 0.0\r\n  z: 0.0\r\n  w: 1.0\r\n\r\nFor the frames I used the following.\r\nTracking Base Frame:  The camera frame\r\nTracking marker Frame: The frame of the tracked markers, in the camera system\r\nRobot Base Frame: The world frame\r\nRobot Effector Frame: The robot gripper frame which holds the ar markers\r\n\r\nDoes anyone know what the issue is or what I did wrong?"}}
