This repository contains the official implementation of the paper titled Generalizable 3D Scene Reconstruction via Divide and Conquer from a Single View.

Andreea Dogaru, Mert Özer, Bernhard Egger

15.07.2024: Inference code is released.
04.04.2024: Paper is available on .

• Interactive scene reconstruction examples can be found on our project page.
• A Dockerfile is provided for easy setup:

docker build --build-arg HF_TOKEN=<USER_TOKEN> -t gen3dsr .
docker run -it --gpus all \
    --mount type=bind,source="$(pwd)/src",target=/app/src \
    --mount type=bind,source="$(pwd)/imgs",target=/app/imgs \
    --mount type=bind,source="$(pwd)/out",target=/app/out \
    gen3dsr python run.py --config ./configs/image.yaml

• Alternatively, after following the detailed local installation instructions presented in INSTALL.md, the code can be run as follows:

cd src
python run.py --config ./configs/image.yaml \
    scene.attributes.img_path='../imgs/demo_1.jpg' \
    scene.save_dir='../out/demo_1'

• We recommend the user to check out the different inference options in image.yaml.
• The reconstruction can be found in <scene.save_dir>/reconstruction.
• The code requires minimum 20GB of VRAM.
