The operator prepare_object_model_3dprepare_object_model_3dPrepareObjectModel3dPrepareObjectModel3dPrepareObjectModel3d prepares the 3D object model
ObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3D for a following operation given in PurposePurposePurposePurposepurpose.
It computes values required for the operation and stores them in
ObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3D, thus speeding up the following operation.
It is not necessary to call prepare_object_model_3dprepare_object_model_3dPrepareObjectModel3dPrepareObjectModel3dPrepareObjectModel3d. However, if the
3D object model is to be used multiple times for the same operation, it
can be faster to do so.
The following values are possible for PurposePurposePurposePurposepurpose:
- 'shape_based_matching_3d'"shape_based_matching_3d""shape_based_matching_3d""shape_based_matching_3d""shape_based_matching_3d":
-
The 3D object model is prepared to be used in
create_shape_model_3dcreate_shape_model_3dCreateShapeModel3dCreateShapeModel3dCreateShapeModel3d. For this, there are no generic
parameters to set.
- 'segmentation'"segmentation""segmentation""segmentation""segmentation":
-
The 3D object model is prepared to be used in
segment_object_model_3dsegment_object_model_3dSegmentObjectModel3dSegmentObjectModel3dSegmentObjectModel3d. For the preparation the 3D
object model must have an attribute with the face triangles and
an attribute with the 3D point coordinates.
If the 3D object model has no attribute with the face triangles, a
simple triangulation is performed. For this, the
3D object model must have an attribute with the 3D point
coordinates and an attribute with the mapping from the point
coordinates to image coordinates. Only points originating from
neighboring pixels are triangulated. Additionally, holes in the
image region can be filled with a Delaunay triangulation
(see 'max_area_holes'"max_area_holes""max_area_holes""max_area_holes""max_area_holes" below). Only holes which are completely
surrounded by the image region are closed.

The 3D object model is prepared to be used in
distance_object_model_3ddistance_object_model_3dDistanceObjectModel3dDistanceObjectModel3dDistanceObjectModel3d.
The parameter OverwriteDataOverwriteDataOverwriteDataOverwriteDataoverwriteData defines if the existing data
of an already prepared 3D object model shall be removed. If
OverwriteDataOverwriteDataOverwriteDataOverwriteDataoverwriteData is set to 'true'"true""true""true""true", the prepared data,
defined with the parameter PurposePurposePurposePurposepurpose, is overwritten. If
OverwriteDataOverwriteDataOverwriteDataOverwriteDataoverwriteData is set to 'false'"false""false""false""false", the prepared data
is not overwritten. The parameter OverwriteDataOverwriteDataOverwriteDataOverwriteDataoverwriteData can be used
for choosing another set of generic parameters GenParamNameGenParamNameGenParamNameGenParamNamegenParamName
and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue. The parameter OverwriteDataOverwriteDataOverwriteDataOverwriteDataoverwriteData
has no influence if the parameter PurposePurposePurposePurposepurpose is
set to 'shape_based_matching_3d'"shape_based_matching_3d""shape_based_matching_3d""shape_based_matching_3d""shape_based_matching_3d", because for that, there
are no generic parameters to set.
The generic parameters can optionally be used to
influence the preparation. If desired, these parameters and their
corresponding values can be specified by using GenParamNameGenParamNameGenParamNameGenParamNamegenParamName
and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue, respectively. The following values for
GenParamNameGenParamNameGenParamNameGenParamNamegenParamName are possible:
- 'max_area_holes'"max_area_holes""max_area_holes""max_area_holes""max_area_holes":
-
This parameter is only valid if
PurposePurposePurposePurposepurpose is set to 'segmentation'"segmentation""segmentation""segmentation""segmentation". The parameter
specifies which area holes of the point coordinates are closed
during a simple Delaunay triangulation. Only holes which are completely
surrounded by the image region are closed.
If 'max_area_holes'"max_area_holes""max_area_holes""max_area_holes""max_area_holes" is set to 0,
no holes are triangulated. If the parameter
'max_area_holes'"max_area_holes""max_area_holes""max_area_holes""max_area_holes" is set greater or equal than 1
pixel, the holes with an area less or equal than
'max_area_holes'"max_area_holes""max_area_holes""max_area_holes""max_area_holes" are closed by a meshing.
