Download the following dataset and link to the project ln -s ./dynamic_replica ./bidastereo/:

Dynamic_Replica

Installation

Installation of BiDAStereo with PyTorch3D, PyTorch 1.12.1 & cuda 11.3

Setup the root for all source files:

git clone https://github.com/TomTomTommi/BiDAStereo
cd bidastereo
export PYTHONPATH=`(cd ../ && pwd)`:`pwd`:$PYTHONPATH

Create a conda env:

conda create -n bidastereo python=3.8
conda activate bidastereo

Install requirements

conda install pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 cudatoolkit=11.3 -c pytorch
pip install "git+https://github.com/facebookresearch/pytorch3d.git@stable"
pip install -r requirements.txt

Evaluation

BiDAStereo trained on SceneFlow
BiDAStereo trained on SceneFlow and Dynamic Replica

To evaluate BiDAStereo:

sh evaluate_bidastereo.sh
sh evaluate_real.sh

The results are evaluated on an A6000 48GB GPU. Evaluation on Dynamic Replica requires a 32GB GPU. If you don't have enough GPU memory, you can modify kernel_size from 20 to 10.

Training

Training requires 8 V100 32GB GPUs or 4 A100 80GB GPUs. You can decrease image_size and / or sample_len if you don't have enough GPU memory.

sh train_bidastereo.sh
