Object DGCNN & DETR3D

This repo contains the implementations of Object DGCNN (https://arxiv.org/abs/2110.06923) and DETR3D (https://arxiv.org/abs/2110.06922). Our implementations are built on top of MMdetection3D.

Prerequisite

1. mmcv (https://github.com/open-mmlab/mmcv)

2. mmdet (https://github.com/open-mmlab/mmdetection)

3. mmseg (https://github.com/open-mmlab/mmsegmentation)

4. mmdet3d (https://github.com/open-mmlab/mmdetection3d)

Data

1. Follow the mmdet3d to process the data.

Train

1. Downloads the pretrained backbone weights to pretrained/

2. For example, to train Object-DGCNN with pillar on 8 GPUs, please use

tools/dist_train.sh projects/configs/obj_dgcnn/pillar.py 8

Evaluation using pretrained models

1. Download the weights accordingly.

2. To test, use
   tools/dist_test.sh projects/configs/obj_dgcnn/pillar_cosine.py /path/to/ckpt 8 --eval=bbox
