Hi Matthieu,
I want to add a little information about my case. So when I start rtabmap, I got a message like this :


MapsManager.cpp:497::updateMapCaches() Occupancy grid for location 804 should be added to global map (e..g, a ROS node is subscribed to any occupancy grid output) but it cannot be found in memory. For convenience, the occupancy grid is regenerated. Make sure parameter "RGBD/CreateOccupancyGrid" is true to avoid this warning for the next locations added to map. For older locations already in database without an occupancy grid map, you can use the "rtabmap-databaseViewer" to regenerate the missing occupancy grid maps and save them back in the database for next sessions. This warning is only shown once.

Does that relate anything to my problem of not generating 2D occupancy grid map ?
