OpenVSLAM is a monocular, stereo, and RGBD visual SLAM system. The notable features are:
- It is compatible with multiple camera models and can be easily customized for other camera models.
- Created maps can be stored and loaded, then OpenVSLAM can localize new images based on the prebuilt maps.
- The system is fully modular. It is designed by encapsulating several functions in separated components with easy-to-understand APIs.
- We provided some code snippets to understand the core functionalities of this system.
One of the noteworthy features of OpenVSLAM is that the system can deal with images captured with multiple camera models, such as perspective, fisheye, and equirectangular. If needed, users can implement extra camera models (e.g. dual fisheye, catadioptric) with ease. For example, visual SLAM algorithm using equirectangular camera models (e.g. RICOH THETA series, insta360 series, etc) is shown above.
Some code snippets to understand the core functionalities of the system are provided.
You can employ these snippets for in your own programs.
Please see the *.cc files in ./example directory or check Simple Tutorial and Example.
We provided documentation for installation and tutorial. Please contact us via GitHub issues if you have any questions or notice any bugs about the software.
Please see Installation chapter in the documentation.
The instructions for Docker users are also provided.
Please see Simple Tutorial chapter in the documentation.
A sample ORB vocabulary file can be downloaded from here. Sample datasets are also provided at here.
If you would like to run visual SLAM with standard benchmarking datasets (e.g. KITTI Odometry dataset), please see SLAM with standard datasets section in the documentation.
