We propose a dynamic HDR NeRF framework, named as HDR-HexPlane, which can learn 3D scenes from dynamic 2D images captured with various exposures. We further construct a dataset containing multiple dynamic scenes captured with diverse exposures for evaluation.

Environment Setup

# create conda environment
conda create --name hdrhexplane python=3.9

# pip install 
pip install -r requirements.txt

Data Preparation

Please download all the data from the link:

Make the dataset format like: dataset/lego.

Please change the "datadir" in config based on the locations of downloaded datasets.

Reconstruction

python main.py config=config/dnerf_slim_tank.yaml

We provide several config files under config folder for different datasets and models.

Evaluation

With render_test=True, render_path=True, results at test viewpoint are automatically evaluated and validation viewpoints are generated after reconstruction.

python main.py config=config/dnerf_slim_airplane.yaml systems.ckpt="checkpoint/path" render_only=True

Citation

Some insights about neural voxel grids and dynamic scenes reconstruction originate from TiNeuVox and hexplane. If you find this repository/work helpful in your research, welcome to cite these papers and give a ⭐.

Acknowledgement

Our code is hugely influenced by hexplane and many other projects. We would like to acknowledge them for making great code openly available for us to use. All the datasets are provided for academic studies only.
