ISMAR 2022

Installation

It is recommended to install Pytorch manually for your hardware platform first. You can then install all dependancies using pip or conda:

pip install -r requirements.txt

After you have installed all third party libraries, run the following script to build extra Pytorch modules used in this project.

sh install.sh

Demo

It is simple to run Vox-Fusion on datasets that already have dataloaders. src/datasets list all existing dataloaders. You can of course build your own, we will come back to it later. For now, we use the replica dataset as an example.

First you have to modify configs/replica/room_0.yaml so the data_path section points to the real dataset path. Now you are all set to run the code:

python demo/run.py configs/replica/room_0.yaml

You should now see a progress bar and some output indicating the system is now running. For now you have to rely on the progress bar to estimate the running time as we are still working on a working GUI.

Custom Datasets

You can use virtually any RGB-D dataset with Vox-Fusion including self-captured ones. Make sure to adapt the config files and dataloaders and put them in the correct folder. Make sure to implement a get_init_pose function for your dataloader, please refer to src/datasets/tum.py for an example.
