Hello Everyone, I am using the Leo rover with a zed2 camera in gazebo for mapping using rtabmap-ros. I have got the mapping part of rtabmap to work but while mapping the objects are being mapped multiple times around creating overlapping. Also, while I run Rviz, the pointcloud of objects are not stationary and slightly moves around with the robot. So in the map, multiple copies of all the objects around, which also overlaps with each other are created

If there are dynamic objects, you would have to use the octomap with ray tracing enabled (Grid/RayTracing to true) and subscribe to /rtabmap/octomap_occupied_space (PointCloud2) or the published octomap (/rtabmap/octomap_full).

Do you need a 3D map or a 2D occupancy grid could be enough? It is because 3D ray tracing is computensively expensive. If 2D map is ok, set Grid/2D to true and subscribe to /rtabmap/grid_map.
