This package integrates orb_slam_2 into ROS in what we believe to be a more user friendly way than what is offered by the original library ORB_SLAM2
Keywords: ROS, ORB_SLAM2, SLAM
The source code is released under a GPLv3 license as is the underlying library ORB_SLAM2.

The orb_slam_2_ros package has been tested under ROS Indigo on Ubuntu 14.04 and under ROS Kinetic Ubuntu 16.04. This is research code, expect that it changes often and any fitness for a particular purpose is disclaimed.
Install Robot Operating System (ROS) (middleware for robotics).

Before launching the node with an example dataset you need to:
- Download a dataset you can use to run this package from EUROC (for example the one called "Machine Hall 001") (containing rosbag to play and camera calibration);
- Download and extract the ORB_SLAM2 vocabulary.
Run the main node with
roslaunch orb_slam_2_ros run_orb_slam_2.launch vocabulary_file_path:=<PATH_TO_EXTRACTED_ORB_SLAM2_VOCABULARY>
Please not that this version of orb_slam_2_ros DOES NOT rectify images, that is why we are using stereo_undistort_node.
