由于发布ORB-SLAM的实验组投诉openvslam有代码侵权,所以openvslam的仓库关闭了,抛开这个话题,从学习的角度来说openvslam确实是一个不错的项目,代码写的更加的标准,而且还支持更多的相机类型,从学习的角度来说直接通过openvslam入门视觉slam,确实要比ORB-SLAM性价比更高一些。
由于仓库的原作者在关闭仓库的同时也删掉了对应的文档,所以初学者可能难以顺利的将openvslam运行起来,可以参考我的博客: 《开源SLAM框架学习——OpenVSLAM源码解析: 第一节 安装和初探》

OpenVSLAM is a monocular, stereo, and RGBD visual SLAM system. The notable features are:
- It is compatible with various type of 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.
OpenVSLAM is based on an indirect SLAM algorithm with sparse features, such as ORB-SLAM, ProSLAM, and UcoSLAM. One of the noteworthy features of OpenVSLAM is that the system can deal with various type of 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.
Visual SLAM is regarded as a next-generation technology for supporting industries such as automotives, robotics, and xR. We released OpenVSLAM as an opensource project with the aim of collaborating with people around the world to accelerate the development of this field. In return, we hope this project will bring safe and reliable technologies for a better society.
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.
