Getting Started

Requirements

git clone https://github.com/yuyanli0831/OmniFusion
cd OmniFusion
python3 -m venv omni-venv
source omni-venv/bin/activate
pip3 install -r requirements.txt

Datasets

We trained and evaluated our method on three datasets Stanford2D3D, 360D, Matterport3D.

FYI, a standard pre-process of the original Matterport3D dataset is applied for the development of 360-image-based depth estimation. Given the downloaded original dataset, the 360 images and depth maps are rendered by a matlab scrpt included in this repo.

Pre-trained models

Our pre-trained models are provided for direct evaluation.

Training

python train_erp_depth.py --fov 80 --patchsize (256, 256) --nrows 4

You can specify the patch fov, patch resolution, patch alignment(3, 4, 5, 6 rows).

Evaluation

python test.py --fov 80 --patchsize (256, 256) --nrows 4

Visualization

For training, visual results will be saved into tensorboard. In addition, depth maps and point clouds will be saved locally during training/evaluation.
