# TinyGrapeKit
## A bunch of state estimation algorithms.
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.
Detailed derivations can be found in: https://www.zhihu.com/column/slamTech
# Install
## Prerequisites
opencv, ceres, Eigen
## Build
```
chmod +x build.sh
./build.sh
```
# Applications in the **app** folder
## FilterFusion : Filter-Based Sensor Fusion.
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
```



### Dataset
We used the KAIST dataset to test our method. https://irap.kaist.ac.kr/dataset/
### Example
For examples, please refer to the **Example** folder.
```
./RunKAISTData ${REPO_PATH}/TinyGrapeKit/app/FilterFusion/params/KAIST.yaml ${KAIST_PATH}
```
