get_deformable_model_contours — Return the contour representation of a deformable model.
The operator get_deformable_model_contours returns a representation of the deformable model ModelID as XLD contours in ModelContours. The parameter Level 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_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_image when using the rectified camera parameters. The rectified camera parameters can be queried by get_deformable_model_params. It should be noted that the position of ModelContours is normalized such that the reference point of the model (see set_deformable_model_origin) lies at the pixel position (0,0). Hence, the contours simply need to be tranformed 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_param.
Contour representation of the deformable model.
Handle of the model.
Pyramid level for which the contour representation should be returned.
Default value: 1
Suggested values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Restriction: Level >= 1
If the handle of the model is valid, the operator get_deformable_model_contours returns the value 2 (H_MSG_TRUE). If necessary an exception is raised.
