Couldn't find executable named point_cloud_aggregator below /opt/ros/noetic/share/rtabmap_util

[moooeeeep]

I've apt installed ros-noetic-rtabmap-ros from the ROS debian packages, and apparantly the point_cloud_aggregator is not part of the installation.

Error message:

[rosrun] Couldn't find executable named point_cloud_aggregator below /opt/ros/noetic/share/rtabmap_util

Tab completion:

$ rosrun rtabmap_util 
data_player               map_assembler             netvlad_tf_ros.py         odom_msg_to_tf            point_cloud_assembler     point_to_tf.py            rgbd_split                yaml_to_camera_info.py    
gazebo_ground_truth.py    map_optimizer             objects_to_tags.py        patrol.py                 pointcloud_to_depthimage  rgbd_relay                transform_to_tf.py        

Is this intended?

Do I need to install from source?

The node is indeed not installed, which is a bug. However, if you want to use it, you should be able to use the nodelet instead:

rosrun nodelet nodelet standalone rtabmap_util/point_cloud_aggregator

Thanks, will try that in the meantime!
