# ROS-Wrapper
Run pose estimator with ros topics as inputs and publish detected poses.
<br>
- Build container:
```bash
docker build --progress=plain -t rapidposetriangulation_ros -f ros/dockerfile .
```
- Update or remove the `ROS_DOMAIN_ID` in `docker-compose.yml` to fit your environment
- Run and test:
```bash
xhost +; docker compose -f ros/docker-compose.yml up
docker exec -it ros-test_node-1 bash
export ROS_DOMAIN_ID=18
```
