• Install depends follow the instructions of "cartographer" and "cartographer_ros" respectively.
• Build OpenCV 3.3.1 (other version may work fine if it includes implementation of SURF keypoint detector) from source with "opencv_contrib"

• Return to the root folder of your ROS workspace (which has the same directory as this "README" file) and run:

  catkin_make_isolated
  

• Some demo sequences can be downloaded via:

  • TONGJI dataset: link, pwd: hfrl

• roslaunch dlio demo_dlio_tongji.launch bag_filename:=BAG_FILE_PATH where BAG_FILE_PATH is the full path of the downloaded bag file in your device

• Some results on the self-collected TONGJI dataset.

  
  

• The dataset is available online at NTU-VIRAL

• ```roslaunch dlio demo_dlio_viral.launch bag_filename:=BAG_FILE_PATH```
  

  where BAG_FILE_PATH is the full path of the downloaded bag file in your device

• Results on VIRAL
  

  
  
  

• The dataset is available online at KAIST

• Play KAIST bag follow the instruction: file_player

• Run your bag as above examples

roslaunch dlio dlio_offline_tongji bag_filenames:=BAG_FILE_PATH

roslaunch dlio dlio_map_viewer_rectified urdf_filename:=tongji pose_graph_pb_filename:=PG_FILENAME range_data_pb_filename:=RD_FILENAME rate:=100

where PG_FILENAME and RD_FILENAME are binary pbstream files saved to disk when launch the offline script above.
