This is the official implementation of HENet: Hybrid Encoding for End-to-end Multi-task 3D Perception from Multi-view Cameras.

Contact us with [email protected], [email protected].

Update

  • 2024/07/07 - HENet has been accepted to ECCV 2024. We will release the code in this repository.

  • 2024/05/09 - We incorporated SparseBEV with HENet and achieved 1st place on the nuScenes leaderboard / Vision track.

  • 2024/04/03 - We released our paper on arXiv.

Introduction

HENet is an end-to-end multi-task 3D perception framework. It reduces training costs through hybrid image encoding and mitigates multi-task conflicts through independent BEV feature encoding.

Demo

Visualization results of HENet and baselines on end-to-end multi-tasking. The proposed HENet estimates occluded objects better through long-term information and have more accurate predictions through high-resolution information.

Main Results

mAP NDS mIoU config model
HENet 49.9 59.9 58.0

Getting Started

Environment

The code is tested in the following two environments:

cuda     12.1
pytorch  2.0.1+cu118 
GPU      A800, A40
(Need to manually comment out the cuda version check of pytorch)
(For a detailed package list, please refer to envs_list_cu121.txt)

cuda     11.3
pytorch  1.12.1+cu113
GPU      RTX8000, RTX3090, V100, P40
(For a detailed package list, please refer to envs_list_cu113.txt)

The most recommended installation steps are:

  1. Create a Python environment. Install PyTorch corresponding to your machine's CUDA version;

  2. Install mmcv corresponding to your PyTorch and CUDA version;

  3. Install other dependencies of mmdet and install mmdet;

  4. Install other dependencies of this project (Please change the spconv version in the requirements.txt to the CUDA version you are using) and setup this project;

python setup.py develop
  1. Compile some operators manually.
cd mmdet3d/ops/csrc
python setup.py build_ext --inplace
cd ../deformattn
python setup.py build install
  1. Install other dependencies of detectron2 and install detectron2;
cd detr2
python setup.py develop

Data Preparation

Please download nuScenes-v1.0-trainval and nuScenes-map-expansion-v1.3 at nuScenes.org and CVPR23-Occupancy/gts.tar.gz at CVPR2023-3D-Occupancy-Prediction.

If your folder structure is different from the following, you may need to change the corresponding paths in config files.

Prepare nuScenes data by running:

python tools/create_data_nuscenes_C.py

Training

./tools/dist_train.sh $config_path $gpus

Testing

Testing on validation set:

./tools/dist_test.sh $config_path $checkpoint_path $gpus --eval bbox

Testing on test set:

./tools/dist_test.sh $config_path $checkpoint_path $gpus --format-only --eval-options 'jsonfile_prefix=work_dirs'
mv work_dirs/pts_bbox/results_nusc.json work_dirs/pts_bbox/{$name}.json

If you have any other questions, please refer to mmdet3d docs.
