How could the robot localize after loading a saved map? about isaac_ros_nvblox HOT 3 CLOSED

Thanks. So ros2 action send_goal /visual_slam/save_map isaac_ros_visual_slam_interfaces/action/SaveMap "{map_url: /map} would be a more appropriate choice for saving a map which could be used for localizing later in the isaac_ros_visual_slam process?

Yes, that would be an appropriate usage of the save_map and load_map_and_localize actions in Isaac ROS Visual SLAM.

nvblox, on its own, is just a mapping pipeline. Mapping being half of Simultaneous Localization and Mapping (SLAM).

In other words, nvblox on its own will not relocalize in a map. We expect another module to do that. You could configure, for example, isaac_ros_visual_slam, or another visual slam system, to do the relocalization.
