3DVL-Codebase

This repo aims to merge our 3DVL works (3DVG-Transformer, 3DJCG, FE-3DGQA, ...) and will be continuously updated, hopefully contributing to subsequent 3D visual language tasks.

For 3D Visual Grounding:

3DVG-Transformer: Relation modeling for visual grounding on point clouds (ICCV 2021)

python scripts/grounding_3dvg_trans_scripts/train_3dvg_transformer.py --use_multiview --use_normal --batch_size 8 --epoch 200 --gpu 0 --verbose 50 --val_step 1000 --lang_num_max 8 --lr 0.002 --coslr --tag 3dvg-trans+

For 3D Joint Training (Visual Grounding & Dense Captioning):

3DJCG: A Unified Framework for Joint Dense Captioning and Visual Grounding on 3D Point Clouds (CVPR 2022)

python scripts/joint_scripts/train_3djcg.py --use_multiview --use_normal --num_locals 20 --batch_size 10 --epoch 200 --gpu 1 --verbose 50 --val_step 1000 --lang_num_max 8 --coslr --lr 0.002 --num_ground_epoch 150 --tag 3djcg

For 3D Grounded Question Answering:

Toward Explainable 3D Grounded Visual Question -Answering: A New Benchmark and Strong Baseline (TCSVT 2022)

python scripts/vqa_scripts/train_3dgqa.py --use_multiview --use_normal --batch_size 8 --epoch 200 --gpu 3 --verbose 50 --val_step 1000 --lang_num_max 8 --coslr --lr 0.002 --tag 3dgqa
