I see. Thanks for the insight.

Well, that's what the imu_transformer claims to do. It transforms sensor_msgs/Imu from one frame to another. It actuall

Thanks, but the implementation is here. And I don't see the acceleration being treated any different than other vectors.

Hi

I am using rtabmap_ros version 0.13.1 with the ZED stereo camera and the VLP16 laser scanner. Even though I enabled the "subscribe to scan cloud" option and used the correct cloud topic name "velodyne_points" rtabmap seems to ignore the subscription.

My objective is simply to use the pose graph and loop closure optimization from rtabmap to display point clouds from VLP16. Can rtabmap store the 3d laser scan at the graph nodes and display them later?

I am using the sample launch file stereo_mapping.launch

Hi, I am using rtabmap using stereo on a robot. Everything seems to work fine, except that the MapCloud does not contain registered clouds. The individual 3D maps (from different graph nodes) "supposedly" are not registered to each other. For example there are multiple (3 or 4) replica of the same scene which are not registered. Here are some details.

• ROS Indigo on Ubuntu 14.04
• rectified/synchronized stereo being published at 15Hz
• odometry available (approx_sync, enabled when using wheel odometry)
• rtabmap database: https://www.dropbox.com/sh/vtp0xao60f...
• launch file https://www.dropbox.com/s/eiumj3fzs7b...

Please help, thanks!

Works perfect! Thanks for the help!

Also checked on rostopic info, it shows there is no subscription to the topic /velodyne_points. I also attached the com

Hi Mathieu, Thank you for the insight. Changed my stereo setup to the "ZED" and works like a charm! Best, Lealem

I would say the problem is with the cloud data (mapping result), everything else seems to work perfect! And I am launchi
