Hi,

as the warning says, did you try:

$ rostopic hz /rtabmap/odom
$ rostopic hz /camera/rgb/image_rect_color
$ rostopic hz /camera/depth/image_rect_color 
$ rostopic hz /camera/rgb/camera_info 

to see if all topics are actually published? If not, the problem is thus why they are not published (maybe wrong topic name).

cheers,
Mathieu
