Official code release accompanying the SIGGRAPH 2023 paper - "ViP-NeRF: Visibility Prior for Sparse Input Neural Radiance Fields". All the published data is available here.
Environment details are available in EnvironmentData/ViP_NeRF_GPU.yml
. The environment can be created using conda
conda env create -f ViP_NeRF_GPU.yml
export PYTHONPATH=<ABSOLUTE_PATH_TO_VIPNERF_DIR>/src:$PYTHONPATH
Please follow the instructions in database_utils/README.md file to set up various databases. Instructions for custom databases are also included here.
Please follow the instructions in prior_generators/sparse_depth/README.md file to generate sparse depth prior.
Please follow the instructions in prior_generators/visibility/README.md file to generate dense visibility prior.
The files RealEstateTrainerTester01.py
, NerfLlffTrainerTester01.py
and DtuTrainerTester01.py
contain the code for training, testing and quality assessment along with the configs for the respective databases.
python RealEstateTrainerTester01.py
python NerfLlffTrainerTester01.py
python DtuTrainerTester01.py
The train configs are also provided in runs/training/train****
folders for each of the scenes. Please download the trained models from here and place them in the appropriate folders. Disable the train call in the TrainerTester files and run the respective files. This will run inference using the pre-trained models and also evaluate the synthesized images and reports the performance. To reproduce results from the paper, use the models trained for 50k iterations. For best results, use the models trained for more iterations.
