## Installation

1. Clone Spann3R

   ```
   git clone https://github.com/HengyiWang/spann3r.git
   cd spann3r
   ```
   
2. Create conda environment

   ```
   conda create -n spann3r python=3.9 cmake=3.14.0
   conda install pytorch==2.3.0 torchvision==0.18.0 torchaudio==2.3.0 pytorch-cuda=11.8 -c pytorch -c nvidia  # use the correct version of cuda for your system
   
   pip install -r requirements.txt
   
   # Open3D has a bug from 0.16.0, please use dev version
   pip install -U -f https://www.open3d.org/docs/latest/getting_started.html open3d
   ```

3. Compile cuda kernels for RoPE

   ```
   cd croco/models/curope/
   python setup.py build_ext --inplace
   cd ../../../
   ```

4. Download the DUSt3R checkpoint

   ```
   mkdir checkpoints
   cd checkpoints
   # Download DUSt3R checkpoints
   wget https://download.europe.naverlabs.com/ComputerVision/DUSt3R/DUSt3R_ViTLarge_BaseDecoder_512_dpt.pth
   ```

5. Download our [checkpoint](https://drive.google.com/drive/folders/1bqtcVf8lK4VC8LgG-SIGRBECcrFqM7Wy?usp=sharing) and place it under `./checkpoints`

## Demo

1. Download the [example data](https://drive.google.com/drive/folders/1bqtcVf8lK4VC8LgG-SIGRBECcrFqM7Wy?usp=sharing) (2 scenes from [map-free-reloc](https://github.com/nianticlabs/map-free-reloc)) and unzip it as `./examples`

2. Run demo:

   ```
   python demo.py --demo_path ./examples/s00567 --kf_every 10 --vis
   ```

   For visualization `--vis`, it will give you a window to adjust the rendering view. Once you find the view to render, please click `space key` and close the window. The code will then do the rendering of the incremental reconstruction.



## Training and Evaluation

### Datasets

We use Habitat, ScanNet++, ScanNet, ArkitScenes, Co3D, and BlendedMVS to train our model. Please refer to [data_preprocess.md](docs/data_preprocess.md).

### Train

Please use the following command to train our model:

```
torchrun --nproc_per_node 8 train.py --batch_size 4
```

### Eval

Please use the following command to evaluate our model:

```
python eval.py
```
