Name

get_deformable_model_contoursT_get_deformable_model_contoursGetDeformableModelContoursGetDeformableModelContoursget_deformable_model_contours — Return the contour representation of a deformable model.

Signature

get_deformable_model_contours( : ModelContours : ModelID, Level : )

Description

The operator get_deformable_model_contoursget_deformable_model_contoursGetDeformableModelContoursGetDeformableModelContoursGetDeformableModelContoursget_deformable_model_contours returns a representation of the deformable model ModelIDModelIDModelIDModelIDmodelIDmodel_id as XLD contours in ModelContoursModelContoursModelContoursModelContoursmodelContoursmodel_contours. The parameter LevelLevelLevelLevellevellevel determines for which pyramid level of the model the contour representation should be returned. The contours can be used, for example, to visualize the found instances of the model in an image.

In case that the model was generated by create_planar_calib_deformable_model_xldcreate_planar_calib_deformable_model_xldCreatePlanarCalibDeformableModelXldCreatePlanarCalibDeformableModelXldCreatePlanarCalibDeformableModelXldcreate_planar_calib_deformable_model_xld, the contours by default are returned in the world coordinate system in metric units. Here, the contours must be transformed by the returned pose for visualizing a match.

In all other cases, the contours of the model by default are returned in the image coordinate system in pixel units. In the calibrated case this system corresponds to the rectified image coordinate system. The rectified image coordinate system is the coordinate system of an image one would obtain by change_radial_distortion_imagechange_radial_distortion_imageChangeRadialDistortionImageChangeRadialDistortionImageChangeRadialDistortionImagechange_radial_distortion_image when using the rectified camera parameters. The rectified camera parameters can be queried by get_deformable_model_paramsget_deformable_model_paramsGetDeformableModelParamsGetDeformableModelParamsGetDeformableModelParamsget_deformable_model_params. It should be noted that the position of ModelContoursModelContoursModelContoursModelContoursmodelContoursmodel_contours is normalized such that the reference point of the model (see set_deformable_model_originset_deformable_model_originSetDeformableModelOriginSetDeformableModelOriginSetDeformableModelOriginset_deformable_model_origin) lies at the pixel position (0,0). Hence, the contours simply need to be transformed by the found homography in the image.

The default behavior for the calibrated case can be changed with the generic parameter 'get_deformable_model_contours_coord_system' of the operator set_deformable_model_paramset_deformable_model_paramSetDeformableModelParamSetDeformableModelParamSetDeformableModelParamset_deformable_model_param.

Execution Information

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

Parameters

ModelContoursModelContoursModelContoursModelContoursmodelContoursmodel_contours (output_object) xld_cont-array → object

Contour representation of the deformable model.

ModelIDModelIDModelIDModelIDmodelIDmodel_id (input_control) deformable_model → (handle)

Handle of the model.

LevelLevelLevelLevellevellevel (input_control) integer → (integer)

Pyramid level for which the contour representation should be returned.

Default: 1

Suggested values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Restriction: Level >= 1

Result

If the handle of the model is valid, the operator get_deformable_model_contoursget_deformable_model_contoursGetDeformableModelContoursGetDeformableModelContoursGetDeformableModelContoursget_deformable_model_contours returns the value 2 ( H_MSG_TRUE) . If necessary an exception is raised.
