Hi community,

I'm new to working with Kinect and ROS in general, so I guess i'm missing something here.

I am using ROS Indigo with Ubuntu 14.04 and the Freenect driver.

I show you the steps I make in case you see something irregular:

So i connect the Kinect to ROS:

$ roslaunch freenect_launch freenect.launch depth_registration:=true

I use this RTAB-MAP command to run my Rviz, although I could use, of course, RTAB-MAP. (I do it this way because like this i don't have to configure myself the Rviz for working with the Kinect):

$ roslaunch rtabmap_ros rgbd_mapping.launch rtabmap_args:="--delete_db_on_start" rviz:=true rtabmapviz:=false

Then the Rviz runs normally until i make relatively fast movements with the Kinect (they aren't really fast, just normal human movements), that's when the data streaming stops (so Rviz doesn't refresh) and I receive this kind of notifications via terminal:

...

....

So this is the main problem, despite that the map that shows in the Rviz is not really accurate and, although it's beautiful to see a 3D map of my living-room, is still some fuzzy itself.

Any thoughts for improving this? Thanks everyone in advance.
