News

2022.06.01 We release the code and models of both BEVDet and BEVDet4D!
2022.04.01 We propose BEVDet4D to lift the scalable BEVDet paradigm from the spatial-only 3D space to the spatial-temporal 4D space. Technical report is released on arixv. [BEVDet4D].
2022.04.01 We upgrade the BEVDet paradigm with some modifications to improve its performance and inference speed. Thchnical report of BEVDet has been updated. [BEVDetv1].
2021.12.23 BEVDet is now on arxiv. [BEVDet].

Get Started

Please follow the guidelines in the original mmdet3d for preparing the repo and dataset.

Please see getting_started.md for the basic usage of MMDetection3D. We provide guidance for quick run with existing dataset and with customized dataset for beginners. There are also tutorials for learning configuration systems, adding new dataset, designing data pipeline, customizing models, customizing runtime settings and Waymo dataset.

Prepare dataset specific for BEVDet4D.

Note: Make sure that data preparation in nuscenes_det.md has been conducted.

cd BEVDet/
python tools/data_converter/prepare_nuscenes_for_bevdet4d.py

Visualize the predicted result with open3d.

Note: make sure that you conduct the visualization locally instead of on the remote server.

cd BEVDet/
python tools/test.py $config $checkpoint --show --show-dir $save-path

Acknowledgement

This project is not possible without multiple great open-sourced code bases. We list some notable examples below.

Beside, there are some other attractive works extend the boundary of BEVDet.

BEVerse for multi-task learning.
BEVFusion for acceleration, multi-task learning, and multi-sensor fusion. (Note: The acceleration method is a concurrent work of that of BEVDet and has some superior characteristics like memory saving and completely equivalent.)
