# ROS2 ORB SLAM3 V1.0 package
A ROS2 package for ORB SLAM3 V1.0. Focus is on native integration with ROS2 ecosystem. This is the `main/humble` branch which only supports ROS 2 Humble. Switch over to `jazzy` branch to use with ROS 2 Jazzy.
My goal is to provide a "bare-bones" starting point for developers in using ORB SLAM3 framework in their ROS 2 projects. Hence, this package will not use any advanced features of ROS 2 such as rviz, tf, launch files etc. The project structure is heavily influenced by the excellent ROS1 port of ORB SLAM3 by [thien94](https://github.com/thien94/orb_slam3_ros/tree/master).
If you find this work useful please consider citing the original ORB-SLAM3 paper and my recent paper that uses this package in solving short-term relocalization (kidnapped robot problem) as shown below

## 0. Preamble
* This package builds [ORB-SLAM3](https://github.com/UZ-SLAMLab/ORB_SLAM3) V1.0 as a shared internal library. Comes included with a number of Thirdparty libraries [DBoW2, g2o, Sophus]
* g2o used is an older version and is incompatible with the latest release found here [g2o github page](https://github.com/RainerKuemmerle/g2o).
* This package differs from other ROS1 wrappers, thien94`s ROS 1 port and ROS 2 wrappers in GitHub by supprting/adopting the following
* A separate python node to send data to the ORB-SLAM3 cpp node. This is purely a design choice.
* At least C++17 and Cmake>=3.8
* Eigen 3.3.0, OpenCV 4.2, latest release of Pangolin
* Comes with a small test image sequence from EuRoC MAV dataset (MH05) to quickly test installation
* For newcomers in ROS2 ecosystem, this package serves as an example of building a shared cpp library and also a package with both cpp and python nodes.
* May not build or work correctly in **resource constrainted hardwares** such as Raspberry Pi 4, Jetson Nano
## Testing platforms
1. Intel i5-9300H, x86_64 bit architecture , Ubuntu 22.04 LTS (Jammy Jellyfish) and RO2 Humble Hawksbill (LTS)
2. AMD Ryzen 5600X, x86_64 bit architecture, Ubuntu 22.04 LTS (Jammy Jellyfish) and RO2 Humble Hawksbill (LTS)
## 1. Prerequisitis
Start with installing the following prerequisits
### Eigen3
```
sudo apt install libeigen3-dev
```
### Pangolin and configuring dynamic library path
We install Pangolin system wide and configure the dynamic library path so the necessary .so from Pangolin can be found by ros2 package during run time. More info here https://robotics.stackexchange.com/questions/105973/ros2-port-of-orb-slam3-can-copy-libdow2-so-and-libg2o-so-using-cmake-but-gettin
#### Install Pangolin
```
cd ~/Documents
git clone https://github.com/stevenlovegrove/Pangolin
cd Pangolin
./scripts/install_prerequisites.sh --dry-run recommended # CExcerpt of 6,573 characters
