[KathiravanNatarajan]

Hi @NilsL3 ,

Nice work !! I am getting this error when running roslaunch orb_slam orb_slam.launch

process[rosout-1]: started with pid [2388]
started core service [/rosout]
process[image_view-2]: started with pid [2391]
process[rviz-3]: started with pid [2392]
ERROR: cannot launch node of type [orb_slam/orb_slam]: can't locate node [orb_slam] in package [orb_slam]

And ORB_SLAM/Frame is not displaying anything and there's no output in rviz either. And In rviz,

No tf data. Actual error: Fixed Frame [ORB_SLAM/Camera] does not exist
