All nodes crashed. Can you try if the standalone works and doesn't crash at start? Simply try:

$ rtabmap

[IlyaPetrovM]

I've tried:

ilya@workstation:~$ rtabmap 
Illegal instruction (core dumped)

[matlabbe]

I know that on some computers (even my laptop), the binaries built by ROS have this issue. I recommend to build rtabmap from source. It seems to be a similar problem than #5.

1. Uninstall ros-hydro-rtabmap:

sudo apt-get remove ros-hydro-rtabmap ros-hydro-rtabmap-ros

2. Install rtabmap_ros from source

[IlyaPetrovM]

Thank you! It works!

I HAVE Same problem and i cant fix it ,I try to install rtabmap by binary i get the segmentation fault error ,and i try to install rtab by source i get "process died error"

please help to fix it

[chiragmajithia]

rtabmap standalone crashes with Segmetation Fault as soon as I start the Mapping. Using Ubuntu 16.04 and ros-kinetic. I installed it using the source.
The rtabmap and rtabmap_ros both compile without errors.
Did anyone face the same issue?

[matlabbe]

Is rtabmap standalone crash too on start?

$ rtabmap

[chiragmajithia]

yes, standalone crashes - as soon as it receives first data from r200 with Segmentation Fault. I tried few more things, which I refer to in the New Issue created.

cross-ref, see debugging instructions here: #28
