TODOs
- Evaluation code and metrics (with ground truth data)
- Model code (with pretrained checkpoint)
- Test-time reconstruction code
- Training (and evaluation) data preparation scripts
How to install the framework
- Clone the repository with submodules:
git clone --recurse-submodules https://github.com/AljazBozic/TransformerFusion.git
- Create Conda environment:
conda env create -f environment.yml
- Compile local C++/CUDA dependencies:
conda activate tf
cd csrc
python setup.py install
Evaluate the reconstructions
We evaluate method performance on the test scenes of ScanNet dataset.
We compare scene reconstructions to the ground truth meshes, obtained with fusion of RGB-D data. Since the ground truth meshes are not complete, we additionally compute occlusion masks of RGB-D scans, to not penalize the reconstructions that are more complete than the ground truth meshes.
You can download both ground truth meshes and occlusion masks here. To evaluate the reconstructions, you need to place them into data/reconstructions, and extract the ground truth data to data/groundtruth. The reconstructions are expected to be named as ScanNet test scenes, e.g. scene0733_00.ply. The following script computes evaluation metrics over all provided scene meshes:
conda activate tf
python src/evaluation/eval.py
