 # VI_ORB_SLAM2: Monocular/Stereo Visual-Inertial ORB-SLAM based on ORB-SLAM2
 
-The repository includes the **Monocular** version and the **Stereo** version of **Visual-Inertial ORB-SLAM**. These two are the no ros version of  [jingpang](https://github.com/jingpang)'s **LearnVIORB (https://github.com/jingpang/LearnVIORB) and [ZuoJiaxing](https://github.com/ZuoJiaxing)'s **[**LearnVIORBnorosgai2**](https://github.com/ZuoJiaxing/LearnVIORBnorosgai2)**. For details, you may refer to  `Examples/Monocular/mono_euroc_VI.cc` and `Examples/Stereo/stereo_euroc_VI.cc`.
