CMD: A Cross Mechanism Domain Adaptation Dataset for 3D Object Detection(ECCV2024)

An multi-mechanism, multi-modal real-world 3D object detection dataset that includes low-resolustion (32 beams) mechanical LiDAR, high-resolustion (128 beams) mechanical LiDAR, solid-state LiDAR, 4D millimeter-wave radar, and cameras. Each sensor is precisely time-synchronized and calibrated, making the dataset suitable for 3D object detection research involving multi-mechanism LiDAR data, particularly for cross-mechanism domain adaptation.

Data Sample

Get Started

1. Installation and Data Preparation

A. Clone this repository.

git clone https://github.com/im-djh/CMD.git

B. Create virtual-env.

conda create -n xmuda python=3.8

C. Install requirements cuda-11.4、cuda-11.6、cuda-11.7 tested

conda activate xmuda
pip install torch==1.13.0+cu116 torchvision==0.14.0+cu116 torchaudio==0.13.0 --extra-index-url https://download.pytorch.org/whl/cu116
pip install spconv-cu116	
pip install -r requirements.txt
python setup.py develop

D. Download the dataset and create dataset infos

ln -s <path-to-the-downloaded-dataset> /xmuda/data/xmu

All the file will be organized as,

CMD
├── data
│   ├── xmu
│   │   │── ImageSets
|   |   |── label
|   |   |── seq**     
├── pcdet
├── tools

• Generate the data infos by running the following command:

 python -m pcdet.datasets.xmu.xmu_dataset --func create_xmu_infos  --cfg_file tools/cfgs/dataset_configs/xmu/xmuda_dataset.yaml

• Generate gt_sampling_database by running the following command:

python -m pcdet.datasets.xmu.xmu_dataset --func create_groundtruth_database  --cfg_file tools/cfgs/dataset_configs/xmu/xmu_dataset.yaml

E. For further steps, please refer to OpenPCDet.

Experimental Results

All LiDAR-based models are trained with 4 GTX 3090 GPU. Due to slight differences in annotation and calculation rules, there may be minor discrepancies between the experimental results and those reported in the paper.
