EMAP enables 3D edge reconstruction from multi-view 2D edge maps.


Installation

git clone https://github.com/cvg/EMAP.git
cd EMAP

conda create -n emap python=3.8
conda activate emap

conda install pytorch==2.1.0 torchvision==0.16.0 torchaudio==2.1.0 pytorch-cuda=12.1 -c pytorch -c nvidia
pip install -r requirements.txt

Datasets

Download datasets:

python scripts/download_data.py

The data is organized as follows:

<scan_id>
|-- meta_data.json      # camera parameters
|-- color               # images for each view
    |-- 0_colors.png
    |-- 1_colors.png
    ...
|-- edge_DexiNed        # edge maps extracted from DexiNed
    |-- 0_colors.png
    |-- 1_colors.png
    ...
|-- edge_PidiNet        # edge maps extracted from PidiNet
    |-- 0_colors.png
    |-- 1_colors.png
    ...

Training and Edge Extraction

To train and extract edges on different datasets, use the following commands:

ABC-NEF_Edge Dataset

bash scripts/run_ABC.bash

Replica_Edge Dataset

bash scripts/run_Replica.bash

DTU_Edge Dataset

bash scripts/run_DTU.bash

Checkpoints

We have uploaded the model checkpoints on Google Drive.

Evaluation

To evaluate extracted edges on ABC-NEF_Edge dataset, use the following commands:

ABC-NEF_Edge Dataset

python src/eval/eval_ABC.py

Code Release Status
