Use this to support Infini_Dyna. If you use it for the Infini_Dyna. Read Infini_Dyna readme to pull and download this package.
However, you can also use this as a seperate orbslam3-ros pacakge for any other projects. You just need to compile it like any other ROS package using catkin_make, see the the following for instructions.
Original ORBSLAM2/3 has rosnode but it stands alone, not in any ROS workspace, which makes us a little bit difficult to use some other ROS perperty. This package put the orbslam3 as a ROS package so you can use the genreal ROS way to compile and use it.
This orbslam3 wrapper is different from other current wrappaer like WrapperOne. The code has no difference than the original code besides adding two scripts for subscrbing to the semgemtation image for dynamic objects. If you have ROS and can compile the original ORBSLAM3, then you should be able to compile this. Anything you change, you just catkin_make and recompile.
Note the ORBSLAM3 here uses original commit number 8ac600a instead of the newest one because I found the newest version doesnt work with rgbd. I am not sure if others work better or worse.
mkdir -p catkin_ws/src
cd catkin_ws/src
git clone https://github.com/arpg/orbslam3.git
cd orbslam3
#If you are using ubuntu20 with opencv4, checkout to the opencv4 version
#git checkout orbslam3_ros_opencv4
./build_thrid_party.sh
cd ../..
catkin_make
Run euroc dataset, run roscore first. Then
cd catkin_ws
source devel/setup.bash
rosrun orbslam3 ros_stereo_inertial src/orbslam3/Vocabulary/ORBvoc.txt src/orbslam3/Examples/Stereo-Inertial/EuRoC.yaml true
Then run the bag
rosbag play /home/zhaozhong/dataset/euroc/MH_03_medium.bag /cam0/image_raw:=/gray_image0 /cam1/image_raw:=/gray_image1 /imu0:=/gx5/imu/data
The none ROS version is also compiled, you can either use ROS or not to run it. For example, the rgbd using ros command
roscd orbslam3
rosrun orbslam3 rgbd_tum Path_to_Vocabulary Path_to_Yaml path_to_dataset path_to_associated.txt
Or without ROS command, just find where is the rgbd_tum executable is
cd catkin_ws/devel/lib/orbslam3
./rgbd_tum Path_to_Vocabulary Path_to_Yaml path_to_dataset path_to_associated.txt
I develop this because I want to use the pose estimation from the ORBSLAM3 in each frame, so if you run the such as the ros_stereo_inertial, you can get the ROS topic /tesse/odom. However, I didnt to too much to publish the sparse map or tf but it shouldnt be too hard to do so. You can use this as a base to develop and publish the information you want.

The Changelog describes the features of each version.
ORB-SLAM3 is the first real-time SLAM library able to perform Visual, Visual-Inertial and Multi-Map SLAM with monocular, stereo and RGB-D cameras, using pin-hole and fisheye lens models. In all sensor configurations, ORB-SLAM3 is as robust as the best systems available in the literature, and significantly more accurate.
We provide examples to run ORB-SLAM3 in the EuRoC dataset using stereo or monocular, with or without IMU, and in the TUM-VI dataset using fisheye stereo or monocular, with or without IMU. Videos of some example executions can be found at ORB-SLAM3 channel.
This software is based on ORB-SLAM2 developed by Raul Mur-Artal, Juan D. Tardos, J. M. M. Montiel and Dorian Galvez-Lopez (DBoW2).

We have tested the library in Ubuntu 16.04 and 18.04, but it should be easy to compile in other platforms. A powerful computer (e.g. i7) will ensure real-time performance and provide more stable and accurate results.
We use the new thread and chrono functionalities of C++11.
We use Pangolin for visualization and user interface. Dowload and install instructions can be found at: https://github.com/stevenlovegrove/Pangolin.
We use OpenCV to manipulate images and features. Dowload and install instructions can be found at: http://opencv.org. Required at leat 3.0. Tested with OpenCV 3.2.0.
Required by g2o (see below). Download and install instructions can be found at: http://eigen.tuxfamily.org. Required at least 3.1.0.
We use modified versions of the DBoW2 library to perform place recognition and g2o library to perform non-linear optimizations. Both modified libraries (which are BSD) are included in the Thirdparty folder.
Required to calculate the alignment of the trajectory with the ground truth. Required Numpy module.

We provide some examples to process input of a monocular, monocular-inertial, stereo, stereo-inertial or RGB-D camera using ROS. Building these examples is optional. These have been tested with ROS Melodic under Ubuntu 18.04.
Clone the repository:
git clone https://github.com/UZ-SLAMLab/ORB_SLAM3.git ORB_SLAM3
We provide a script build.sh to build the Thirdparty libraries and ORB-SLAM3. Please make sure you have installed all required dependencies (see section 2). Execute:
cd ORB_SLAM3
chmod +x build.sh
./build.sh
This will create libORB_SLAM3.so at lib folder and the executables in Examples folder.
EuRoC dataset was recorded with two pinhole cameras and an inertial sensor. We provide an example script to launch EuRoC sequences in all the sensor configurations.
-
Download a sequence (ASL format) from http://projects.asl.ethz.ch/datasets/doku.php?id=kmavvisualinertialdatasets
-
Open the script "euroc_examples.sh" in the root of the project. Change pathDatasetEuroc variable to point to the directory where the dataset has been uncompressed.
-
Execute the following script to process all the sequences with all sensor configurations:
./euroc_examples
EuRoC provides ground truth for each sequence in the IMU body reference. As pure visual executions report trajectories centered in the left camera, we provide in the "evaluation" folder the transformation of the ground truth to the left camera reference. Visual-inertial trajectories use the ground truth from the dataset.
Execute the following script to process sequences and compute the RMS ATE:
./euroc_eval_examples
TUM-VI dataset was recorded with two fisheye cameras and an inertial sensor.
-
Download a sequence from https://vision.in.tum.de/data/datasets/visual-inertial-dataset and uncompress it.
-
Open the script "tum_vi_examples.sh" in the root of the project. Change pathDatasetTUM_VI variable to point to the directory where the dataset has been uncompressed.
-
Execute the following script to process all the sequences with all sensor configurations:
./tum_vi_examples
In TUM-VI ground truth is only available in the room where all sequences start and end. As a result the error measures the drift at the end of the sequence.
Execute the following script to process sequences and compute the RMS ATE:
./tum_vi_eval_examples
Tested with ROS Melodic and ubuntu 18.04.
- Add the path including Examples/ROS/ORB_SLAM3 to the ROS_PACKAGE_PATH environment variable. Open .bashrc file:
gedit ~/.bashrc
and add at the end the following line. Replace PATH by the folder where you cloned ORB_SLAM3:
export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:PATH/ORB_SLAM3/Examples/ROS
- Execute
build_ros.shscript:
chmod +x build_ros.sh
./build_ros.sh
For a monocular input from topic /camera/image_raw run node ORB_SLAM3/Mono. You will need to provide the vocabulary file and a settings file. See the monocular examples above.
rosrun ORB_SLAM3 Mono PATH_TO_VOCABULARY PATH_TO_SETTINGS_FILE
For a monocular input from topic /camera/image_raw and an inertial input from topic /imu, run node ORB_SLAM3/Mono_Inertial. Setting the optional third argument to true will apply CLAHE equalization to images (Mainly for TUM-VI dataset).
rosrun ORB_SLAM3 Mono PATH_TO_VOCABULARY PATH_TO_SETTINGS_FILE [EQUALIZATION]
For a stereo input from topic /camera/left/image_raw and /camera/right/image_raw run node ORB_SLAM3/Stereo. You will need to provide the vocabulary file and a settings file. For Pinhole camera model, if you provide rectification matrices (see Examples/Stereo/EuRoC.yaml example), the node will recitify the images online, otherwise images must be pre-rectified. For FishEye camera model, rectification is not required since system works with original images:
rosrun ORB_SLAM3 Stereo PATH_TO_VOCABULARY PATH_TO_SETTINGS_FILE ONLINE_RECTIFICATION
For a stereo input from topics /camera/left/image_raw and /camera/right/image_raw, and an inertial input from topic /imu, run node ORB_SLAM3/Stereo_Inertial. You will need to provide the vocabulary file and a settings file, including rectification matrices if required in a similar way to Stereo case:
rosrun ORB_SLAM3 Stereo_Inertial PATH_TO_VOCABULARY PATH_TO_SETTINGS_FILE ONLINE_RECTIFICATION [EQUALIZATION]
For an RGB-D input from topics /camera/rgb/image_raw and /camera/depth_registered/image_raw, run node ORB_SLAM3/RGBD. You will need to provide the vocabulary file and a settings file. See the RGB-D example above.
rosrun ORB_SLAM3 RGBD PATH_TO_VOCABULARY PATH_TO_SETTINGS_FILE
Running ROS example: Download a rosbag (e.g. V1_02_medium.bag) from the EuRoC dataset (http://projects.asl.ethz.ch/datasets/doku.php?id=kmavvisualinertialdatasets). Open 3 tabs on the terminal and run the following command at each tab for a Stereo-Inertial configuration:
roscore
rosrun ORB_SLAM3 Stereo_Inertial Vocabulary/ORBvoc.txt Examples/Stereo-Inertial/EuRoC.yaml true
rosbag play --pause V1_02_medium.bag /cam0/image_raw:=/camera/left/image_raw /cam1/image_raw:=/camera/right/image_raw /imu0:=/imu
Once ORB-SLAM3 has loaded the vocabulary, press space in the rosbag tab.
Remark: For rosbags from TUM-VI dataset, some play issue may appear due to chunk size. One possible solution is to rebag them with the default chunk size, for example:
rosrun rosbag fastrebag.py dataset-room1_512_16.bag dataset-room1_512_16_small_chunks.bag
A flag in include\Config.h activates time measurements. It is necessary to uncomment the line #define REGISTER_TIMES to obtain the time stats of one execution which is shown at the terminal and stored in a text file(ExecTimeMean.txt).
