[WACV 2024] StreamMapNet: Streaming Mapping Network for Vectorized Online HD Map Construction

Introduction

This repository is an official implementation of StreamMapNet.

Getting Started

1. Environment

Step 1. Create conda environment and activate it.

conda create --name streammapnet python=3.8 -y
conda activate streammapnet

Step 2. Install PyTorch.

pip install torch==1.9.0+cu111 torchvision==0.10.0+cu111 torchaudio==0.9.0 -f https://download.pytorch.org/whl/torch_stable.html

Step 3. Install MMCV series.

# Install mmcv-series
pip install mmcv-full==1.6.0
pip install mmdet==2.28.2
pip install mmsegmentation==0.30.0
git clone https://github.com/open-mmlab/mmdetection3d.git
cd mmdetection3d
git checkout v1.0.0rc6 
pip install -e .

Step 4. Install other requirements.

pip install -r requirements.txt

2. Data Preparation

Step 1. Download NuScenes dataset to ./datasets/nuScenes.

Step 2. Download Argoverse2 (sensor) dataset to ./datasets/av2.

Step 3. Generate annotation files for NuScenes dataset.

python tools/nuscenes_converter.py --data-root ./datasets/nuScenes --newsplit

Step 4. Generate annotation files for Argoverse2 dataset.

python tools/argoverse_converter.py --data-root ./datasets/av2 --newsplit

3. Training and Validating

To train a model with 8 GPUs:

bash tools/dist_train.sh ${CONFIG} 8

To validate a model with 8 GPUs:

bash tools/dist_test.sh ${CONFIG} ${CEHCKPOINT} 8 --eval

To test a model's inference speed:

python tools/benchmark.py ${CONFIG} ${CEHCKPOINT}
