Making a copy of a frame from an about to be terminated node?
I'm using the roslaunch API to shut down a amcl_demo.launch, which has /map frame, and I'm transforming a frame /astra_camera_link to it. These two frames don't exist at the same time because I have to shut either one down due to some conflict in using my RGBd camera. Is there anyway to make a copy of a frame then I can find the transform between these two frames?
