rtabmap_ros: [map_optimizer-3] process has died

[KamalDSOberoi]

Hello,

I am working with rtabmap_ros on ROS Indigo. When I launch the package, rtabmap starts but after sometime map_optimizer dies. I have checked the similar topics on this forum and the only solution I found was to install rtabmap_ros from source.

1. Is there any way to verify if the package has been installed from source or using binaries, after it has been installed? Actually, someone else installed ROS and all the packages when he was working on this project. Now I have took over from him, so I am not sure how he has installed the packages.

2. Also, on the github page it says that there is some issue for ROS Hydro and rtabmap_ros installed using binaries, but doesn't say anything for ROS Indigo. So what could be the problem in my case?

Any help is appreciated. Thanks in advance!!

Hi,

It has been a while since I used the map_optimizer node, there could be a regression error (I opened an issue here). If you have more info about your setup/launch files, you can update the issue.

To know if the binaries are installed, you can list installed apps:

$ dpkg --get-selections | grep rtabmap
ros-indigo-rtabmap				deinstall

"deinstall" means that the binaries are not installed. You can also look in synaptic.

The hydro binaries are stuck at 0.8. You can build rtabmap from source to use the latest version on Hydro.

cheers
