Hello. I am having problems showing anything in my image view when I follow the "creating a map with Erle-Rover" example. all i get is a blank view. does anyone have suggestions or steps I should follow?
terminal1:
roslaunch ros_erle_rover_navigation roverslam.launch (slam + include rviz)
terminal2:
rosrun hector_compressed_map_transport map_to_image_node
terminal3:
rosrun image_view image_view image:=/map_image/full imagetransport:=compressed
so what I am getting is this:

i think it is related to why i am having problems with /scan publishing anything.
