 BEVFusion is based on [mmdetection3d](https://github.com/open-mmlab/mmdetection3d). It is also greatly inspired by the following outstanding contributions to the open-source community: [LSS](https://github.com/nv-tlabs/lift-splat-shoot), [BEVDet](https://github.com/HuangJunjie2017/BEVDet), [TransFusion](https://github.com/XuyangBai/TransFusion), [CenterPoint](https://github.com/tianweiy/CenterPoint), [MVP](https://github.com/tianweiy/MVP), [FUTR3D](https://arxiv.org/abs/2203.10642), [CVT](https://github.com/bradyz/cross_view_transformers) and [DETR3D](https://github.com/WangYueFt/detr3d). 
 
-Please also check out related papers in the camera-only 3D perception community such as [BEVDet4D](https://arxiv.org/abs/2203.17054), [BEVerse](https://arxiv.org/abs/2205.09743), [BEVFormer](https://arxiv.org/abs/2203.17270), [M2BEV](https://arxiv.org/abs/2204.05088) and [PETR](https://arxiv.org/abs/2203.05625), which might be interesting future extensions to BEVFusion.
