 This package is part of the *3d_navigation* project, so you need to install all the necessary packages in the project to see it running.
 More specifically, this hole detector works after using a filtering chain aplied to the original pointcloud generated by the camera. This means that you need the package *iri_3dnav* for launchers and the package *pcl* for voxel dodwnsampling.
+In addition, for compilation, several packages are necessary: *iri_base_algorithm*, *sensor_msgs*, *pcl_ros*, and *iriutils*.
