Name

Signature

Description

The operator refine_surface_model_poserefine_surface_model_poseRefineSurfaceModelPoseRefineSurfaceModelPoseRefineSurfaceModelPose refines the approximate pose InitialPoseInitialPoseInitialPoseInitialPoseinitialPose of the surface model SurfaceModelIDSurfaceModelIDSurfaceModelIDSurfaceModelIDsurfaceModelID in the 3D scene ObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3D. The surface model SurfaceModelIDSurfaceModelIDSurfaceModelIDSurfaceModelIDsurfaceModelID must have been created previously with create_surface_modelcreate_surface_modelCreateSurfaceModelCreateSurfaceModelCreateSurfaceModel or read_surface_modelread_surface_modelReadSurfaceModelReadSurfaceModelReadSurfaceModel. Additionally, set_surface_model_paramset_surface_model_paramSetSurfaceModelParamSetSurfaceModelParamSetSurfaceModelParam can be used to set certain parameters that influence the refinement, such as restricting the allowed range of rotations.

refine_surface_model_poserefine_surface_model_poseRefineSurfaceModelPoseRefineSurfaceModelPoseRefineSurfaceModelPose is useful if the pose of an object in a scene is approximately known and only needs to be refined. The refined pose is returned in PosePosePosePosepose, along with a score in ScoreScoreScoreScorescore. It is possible to pass multiple poses for refinement. Note that, contrary to find_surface_modelfind_surface_modelFindSurfaceModelFindSurfaceModelFindSurfaceModel, the returned poses are not sorted by their score but are returned in the same order as the input poses.

The maximum possible error in the approximate pose that can still be refined depends on the type of object, the amount of clutter in the scene and the visible parts of the objects. In general, differences in the orientation of up to 15° and differences in the position of up to 10% can be refined.

The accuracy of the pose refinement is limited to around 0.1% of the model's size due to numerical reasons. The accuracy further depends on the noise of the scene points, the number of scene points and the shape of the model.

Details about the pose refinement and the parameters are described in the documentation of find_surface_modelfind_surface_modelFindSurfaceModelFindSurfaceModelFindSurfaceModel in the section about the dense pose refinement step. The following generic parameters can be set for refine_surface_model_poserefine_surface_model_poseRefineSurfaceModelPoseRefineSurfaceModelPoseRefineSurfaceModelPose, and are also documented in find_surface_modelfind_surface_modelFindSurfaceModelFindSurfaceModelFindSurfaceModel: 'pose_ref_num_steps'"pose_ref_num_steps""pose_ref_num_steps""pose_ref_num_steps""pose_ref_num_steps", 'pose_ref_sub_sampling'"pose_ref_sub_sampling""pose_ref_sub_sampling""pose_ref_sub_sampling""pose_ref_sub_sampling", 'pose_ref_dist_threshold_rel'"pose_ref_dist_threshold_rel""pose_ref_dist_threshold_rel""pose_ref_dist_threshold_rel""pose_ref_dist_threshold_rel", 'pose_ref_dist_threshold_abs'"pose_ref_dist_threshold_abs""pose_ref_dist_threshold_abs""pose_ref_dist_threshold_abs""pose_ref_dist_threshold_abs", 'pose_ref_scoring_dist_rel'"pose_ref_scoring_dist_rel""pose_ref_scoring_dist_rel""pose_ref_scoring_dist_rel""pose_ref_scoring_dist_rel", 'pose_ref_scoring_dist_abs'"pose_ref_scoring_dist_abs""pose_ref_scoring_dist_abs""pose_ref_scoring_dist_abs""pose_ref_scoring_dist_abs", 'score_type'"score_type""score_type""score_type""score_type", 'pose_ref_use_scene_normals'"pose_ref_use_scene_normals""pose_ref_use_scene_normals""pose_ref_use_scene_normals""pose_ref_use_scene_normals", '3d_edge_min_amplitude_rel'"3d_edge_min_amplitude_rel""3d_edge_min_amplitude_rel""3d_edge_min_amplitude_rel""3d_edge_min_amplitude_rel", '3d_edge_min_amplitude_abs'"3d_edge_min_amplitude_abs""3d_edge_min_amplitude_abs""3d_edge_min_amplitude_abs""3d_edge_min_amplitude_abs", '3d_edges'"3d_edges""3d_edges""3d_edges""3d_edges", 'pose_ref_dist_threshold_edges_rel'"pose_ref_dist_threshold_edges_rel""pose_ref_dist_threshold_edges_rel""pose_ref_dist_threshold_edges_rel""pose_ref_dist_threshold_edges_rel", 'pose_ref_dist_threshold_edges_abs'"pose_ref_dist_threshold_edges_abs""pose_ref_dist_threshold_edges_abs""pose_ref_dist_threshold_edges_abs""pose_ref_dist_threshold_edges_abs", 'pose_ref_scoring_dist_edges_rel'"pose_ref_scoring_dist_edges_rel""pose_ref_scoring_dist_edges_rel""pose_ref_scoring_dist_edges_rel""pose_ref_scoring_dist_edges_rel", and 'pose_ref_scoring_dist_edges_abs'"pose_ref_scoring_dist_edges_abs""pose_ref_scoring_dist_edges_abs""pose_ref_scoring_dist_edges_abs""pose_ref_scoring_dist_edges_abs".

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

This operator supports cancelling timeouts and interrupts.

Parameters

Result

refine_surface_model_poserefine_surface_model_poseRefineSurfaceModelPoseRefineSurfaceModelPoseRefineSurfaceModelPose returns 2 (H_MSG_TRUE) if all parameters are correct. If necessary, an exception is raised.
