Toolkit for the FewSOL dataset

To use the toolkit, first download the FewSOL dataset from here. Download all the zip files, and unzip them into a FewSOL folder. Create a symbol link of the dataset in the root folder of this repo.

cd $ROOT
ln -s $FewSOL_DATA FewSOL

The dataset should have the following structure.

├── ...

Installation

1. create and activate a conda environment

conda create --name fewsol
conda activate fewsol

2. install python packages

pip install -r requirements.txt

3. Use conda to install pytorch. For example,

conda install pytorch torchvision torchaudio cudatoolkit=11.6 -c pytorch -c conda-forge

4. compile the utility functions with:

./build.sh

5. (optional) install the ar_track_alvar ros package

Regarding Object Poses in the Real Object Data

The object pose is computed using RANSAC with the AR tags poses. We assume the object is in the center of the marker board, and compute the center of the marker board as the object pose. The function to compute the object pose is the compute_marker_board_center() function in tools/image_loader.py. Please check this function if you want to use the object poses in our dataset.

Visualization of data
