Description

Finds well-singulated cuboids supported by a surface within a point cloud.

This behavior makes some assumptions about the environment:

• The input point cloud must include a large flat surface, such as a tabletop or floor.
• The filtering and cropping steps are expected to remove all points which are far away from this surface.
• After filtering, all remaining clusters of points are assumed to be objects which are supported by the surface.

The output GraspableObjects will be transformed so that their parent frame is the frame defined by the base_frame config parameter.

plane_model_threshold	input	double
cluster_distance_threshold	input	double

compute()

tl::expected< void, std::string > moveit_pro::behaviors::FindSingularCuboids::compute (const sensor_msgs::msg::PointCloud2 & point_cloud_msg, const moveit_studio::point_cloud_tools::SingularCuboidFinderConfig & config, const std::string & base_frame)

Extract cuboids from the point cloud and set detected cuboids as an output data port.

Parameters

point_cloud_msg	Point cloud to process.
config	Settings to configure point cloud processing.

Returns

BT::NodeStatus::SUCCESS if cuboid detection succeeded. BT::NodeStatus::FAILURE if there was an error.

Private Member Attributes

compute_future_

ThreadedFuture<tl::expected<void, std::string> > moveit_pro::behaviors::FindSingularCuboids::compute_future_

Future associated with the asynchronous compute process.

When set, will contain a result that shows if the process succeeded or failed. Declared last so its joining destructor runs before any sibling member the background task dereferences is destroyed.

Definition at line 91 of file find_singular_cuboids.hpp.

status_

BT::NodeStatus moveit_pro::behaviors::FindSingularCuboids::status_

Holds the behavior status.

visual_tools_

rviz_visual_tools::RvizVisualToolsPtr moveit_pro::behaviors::FindSingularCuboids::visual_tools_

Tool to publish debug visualizations.
