How to rewrite the frameid in a rosbag?
I recorded a rosbag and tried to visualize it in Rviz. I get the following message MessageFilter [target=left_hand ]: Discarding message from [unknown_publisher] due to empty frame_id. This message will only print once.
On doing a rostopic echo, I can see that the frame_id is empty. I ran rosrun tf view_frames
to generate the pdf.
How do I rewrite the header frame id?
