Project page | Paper | Youtube | Bilibili

Installation

Clone this repository and checkout dev branch

git clone https://github.com/YikangZhang1641/VAD-GS.git
git checkout -b dev origin/dev

Build tools

1. Install COLMAP (tested version 3.10-dev)
2. Build SIBR_viewer following the tutorial of 3DGS

Set up the environment

# Create and sync the environment with uv
uv venv

# Install project dependencies
# On Linux, uv resolves torch/torchvision from the PyTorch cu124 index.
uv sync

Example

• We provide a nuScenes example here. Download and extract it to the folder path above.

For training:

python train.py --config configs/example/nuscenes_train_000.yaml

To generate visual outputs:

python render.py --config configs/example/nuscenes_train_000.yaml mode evaluate

For evaluation:

python metrics.py --config configs/example/nuscenes_train_000.yaml
