stereo mapping

[hazem]

When trying to to use my stereo camera the graph view stays blank and the loop hypothesis screen stays black and when using rviz it says no map received when subscribed to thre topic "rtabmap/gridmap"

Hi,

Are all nodes running on the same computer? Do you have warnings in the terminal? It is like you are in localization mode without a map.

cheers,
