 - Only one detection network (PointPillars) was implemented in this repo, so the code may be more easy to read. 
 - Sincere thanks for the great open-source architectures [mmcv](https://github.com/open-mmlab/mmcv), [mmdet](https://github.com/open-mmlab/mmdetection) and [mmdet3d](https://github.com/open-mmlab/mmdetection3d), which helps me to learn 3D detetion and implement this repo.
