Hi,
"--params-all" doesn't exist anymore, I updated the doc.
To see parameters used by rtabmap and rgbd_odometry nodes:
$ rosrun rtabmap_ros rtabmap --params
$ rosrun rtabmap_ros rgbd_odometry --params
To see all combined parameters:
$ rtabmap --params
Note that these parameters are those used by the RTAB-Map library. For ROS related parameters (synchronization, topic subscription...), see
rtabmap_ros page.
cheers,
Mathieu
