Metric localization performance

⛵ Build instructions

Dependencies:

Eigen 3.3
OpenCV 3.4
Ceres 1.14
Sophus 1.0

Note: this code has been build and tested on Ubuntu 18.04, but it should compile for newer versions of Ubuntu.

📥 Dataset

You may need to download nuScenes dataset (radar) from nutonomy/nuscenes-devkit.

🚕 Examples

1. preprocess Nuscenes dataset to get loop closure cases and compensate for doppler effect in each radar submap.

cd ./preprocess
python search_for_loopclosure.py -n PATH_TO_NUSCENES
python list_seq.py

2. metric localization process

cd ~/DCRML
mkdir build
cd ./build
cmake ../DCRML
make
./DCRML
