EDM: Efficient Deep Feature Matching

https://github.com/user-attachments/assets/f7e0e026-6b57-4577-a26c-185f82be725e

Installation

conda env create -f environment.yaml
conda activate edm
conda install pytorch==2.0.0 torchvision==0.15.0 torchaudio==2.0.0 pytorch-cuda=11.8 -c pytorch -c nvidia -y
pip install -r requirements.txt 

We provide our pretrained model and a fixed onnx model in google drive and Baidu Netdisk. Please place ckpt in folder weights/ and onnx model in folder deploy/.

Demo

See demo_single_pair.ipynb

Deployment

See subdirectory deploy

ONNX Model

Exporting onnx model first:

cd deploy
pip install -r requirements_deploy.txt 
python export_onnx.py

Run demo on ONNX Runtime using TensorRT backend:

python run_onnx.py

C++ Inference demo

Refer to edm_onnx_cpp

Testing

Setup the testing subsets of ScanNet and MegaDepth first.

The test and training can be downloaded by download link provided by LoFTR.

Create symlinks from the previously downloaded datasets to data/{{dataset}}/test.

# set up symlinks
ln -s /path/to/scannet-1500-testset/* data/scannet/test
ln -s /path/to/megadepth-1500-testset/* data/megadepth/test

MegaDepth dataset

bash scripts/reproduce_test/outdoor.sh

ScanNet dataset

bash scripts/reproduce_test/indoor.sh

Training

Prepare training data according to the settings of LoFTR.

bash scripts/reproduce_train/outdoor.sh
