This repo is divided into two parts, one is the basic algorithm, in the library folder. The other is the actual multi-sensor fusion algorithm (e.g. SLAM), in the app folder.

Fuse wheel, visual, and GNSS in an Extended Kalman Filter.

For visual-wheel fusion, please refer to: https://zhuanlan.zhihu.com/p/270670373

For fusing of GNSS data, please refer to: https://zhuanlan.zhihu.com/p/330880853

You can select the sensors to participate in the fusion through the configuration file.

sys_config.enable_plane_update: 1
sys_config.enable_gps_update: 1

We used the KAIST dataset to test our method. https://irap.kaist.ac.kr/dataset/

For examples, please refer to the Example folder.
