描述
determine_deformable_model_paramsdetermine_deformable_model_paramsDetermineDeformableModelParamsDetermineDeformableModelParamsDetermineDeformableModelParamsdetermine_deformable_model_params determines certain parameters
of a deformable model automatically from the model image
TemplateTemplateTemplateTemplatetemplatetemplate. The parameters to be determined can be specified
with ParametersParametersParametersParametersparametersparameters. determine_deformable_model_paramsdetermine_deformable_model_paramsDetermineDeformableModelParamsDetermineDeformableModelParamsDetermineDeformableModelParamsdetermine_deformable_model_params can
be used to determine the same parameters that are determined
automatically when the respective parameter in
create_planar_uncalib_deformable_modelcreate_planar_uncalib_deformable_modelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelcreate_planar_uncalib_deformable_model is set to 'auto'"auto""auto""auto""auto""auto"：the number of pyramid levels (ParametersParametersParametersParametersparametersparameters =
'num_levels'"num_levels""num_levels""num_levels""num_levels""num_levels"), the angle step length (ParametersParametersParametersParametersparametersparameters
= 'angle_step'"angle_step""angle_step""angle_step""angle_step""angle_step"), the scale step length
(ParametersParametersParametersParametersparametersparameters = 'scale_step'"scale_step""scale_step""scale_step""scale_step""scale_step" for isotropic scaling
and 'scale_r_step'"scale_r_step""scale_r_step""scale_r_step""scale_r_step""scale_r_step" and/or 'scale_c_step'"scale_c_step""scale_c_step""scale_c_step""scale_c_step""scale_c_step" for
anisotropic scaling), the kind of optimization (ParametersParametersParametersParametersparametersparameters
= 'optimization'"optimization""optimization""optimization""optimization""optimization"), the threshold (ParametersParametersParametersParametersparametersparameters =
'contrast'"contrast""contrast""contrast""contrast""contrast") or the hysteresis thresholds
(ParametersParametersParametersParametersparametersparameters = 'contrast_hyst'"contrast_hyst""contrast_hyst""contrast_hyst""contrast_hyst""contrast_hyst") for the contrast,
the minimum size of the object parts (ParametersParametersParametersParametersparametersparameters =
'min_size'"min_size""min_size""min_size""min_size""min_size"), and the minimum contrast (ParametersParametersParametersParametersparametersparameters
= 'min_contrast'"min_contrast""min_contrast""min_contrast""min_contrast""min_contrast"). By passing a tuple of the above
values in ParametersParametersParametersParametersparametersparameters, an arbitrary combination of these
parameters can be determined. If all of the above parameters should
be determined, the value 'all'"all""all""all""all""all" can be passed. In this case
both hysteresis thresholds are determined, i.e., the operator
behaves like passing 'contrast_hyst'"contrast_hyst""contrast_hyst""contrast_hyst""contrast_hyst""contrast_hyst" instead of
'contrast'"contrast""contrast""contrast""contrast""contrast".
determine_deformable_model_paramsdetermine_deformable_model_paramsDetermineDeformableModelParamsDetermineDeformableModelParamsDetermineDeformableModelParamsdetermine_deformable_model_params is mainly useful to determine
the above parameters before creating the model, e.g., in an
interactive system, which makes suggestions for these parameters to
the user, but enables the user to modify the suggested values.
The automatically determined parameters are returned as a name-value
pair in ParameterNameParameterNameParameterNameParameterNameparameterNameparameter_name and ParameterValueParameterValueParameterValueParameterValueparameterValueparameter_value. The
parameter names in ParameterNameParameterNameParameterNameParameterNameparameterNameparameter_name are identical to the names
in ParametersParametersParametersParametersparametersparameters, where, of course, the value 'all'"all""all""all""all""all"
is replaced by the actual parameter names. An exception is the
parameter 'contrast_hyst'"contrast_hyst""contrast_hyst""contrast_hyst""contrast_hyst""contrast_hyst", for which the two values
'contrast_low'"contrast_low""contrast_low""contrast_low""contrast_low""contrast_low" and 'contrast_high'"contrast_high""contrast_high""contrast_high""contrast_high""contrast_high" are returned.
The remaining parameters (NumLevelsNumLevelsNumLevelsNumLevelsnumLevelsnum_levels, AngleStartAngleStartAngleStartAngleStartangleStartangle_start,
AngleExtentAngleExtentAngleExtentAngleExtentangleExtentangle_extent, ScaleMinScaleMinScaleMinScaleMinscaleMinscale_min, ScaleMaxScaleMaxScaleMaxScaleMaxscaleMaxscale_max,
OptimizationOptimizationOptimizationOptimizationoptimizationoptimization, MetricMetricMetricMetricmetricmetric, ContrastContrastContrastContrastcontrastcontrast, and
MinContrastMinContrastMinContrastMinContrastminContrastmin_contrast) have the same meaning as in
create_planar_uncalib_deformable_modelcreate_planar_uncalib_deformable_modelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelcreate_planar_uncalib_deformable_model and
find_planar_uncalib_deformable_modelfind_planar_uncalib_deformable_modelFindPlanarUncalibDeformableModelFindPlanarUncalibDeformableModelFindPlanarUncalibDeformableModelfind_planar_uncalib_deformable_model。The description of these
parameters can be looked up with these operators. These parameters
are used by determine_deformable_model_paramsdetermine_deformable_model_paramsDetermineDeformableModelParamsDetermineDeformableModelParamsDetermineDeformableModelParamsdetermine_deformable_model_params to calculate the
parameters to be determined in the same manner as in
create_planar_uncalib_deformable_modelcreate_planar_uncalib_deformable_modelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelCreatePlanarUncalibDeformableModelcreate_planar_uncalib_deformable_model。It should be noted that if
the parameters of a deformable model with isotropic scaling should be
determined, i.e., if ParametersParametersParametersParametersparametersparameters contains
'scale_step'"scale_step""scale_step""scale_step""scale_step""scale_step" either explicitly or implicitly via
'all'"all""all""all""all""all", the parameters ScaleMinScaleMinScaleMinScaleMinscaleMinscale_min and
ScaleMaxScaleMaxScaleMaxScaleMaxscaleMaxscale_max must contain one value each. If the parameters of
a deformable model with anisotropic scaling should be determined, i.e.,
if ParametersParametersParametersParametersparametersparameters contains 'scale_r_step'"scale_r_step""scale_r_step""scale_r_step""scale_r_step""scale_r_step" or
'scale_c_step'"scale_c_step""scale_c_step""scale_c_step""scale_c_step""scale_c_step" either explicitly or implicitly, the
parameters ScaleMinScaleMinScaleMinScaleMinscaleMinscale_min and ScaleMaxScaleMaxScaleMaxScaleMaxscaleMaxscale_max must contain two
values each. In this case, the first value of the respective
parameter refers to the scaling in row direction, while the
second value refers to scaling in the column direction.
Note that in determine_deformable_model_paramsdetermine_deformable_model_paramsDetermineDeformableModelParamsDetermineDeformableModelParamsDetermineDeformableModelParamsdetermine_deformable_model_params some parameters
appear that can also be determined automatically
(NumLevelsNumLevelsNumLevelsNumLevelsnumLevelsnum_levels, OptimizationOptimizationOptimizationOptimizationoptimizationoptimization, ContrastContrastContrastContrastcontrastcontrast,
MinContrastMinContrastMinContrastMinContrastminContrastmin_contrast). If these parameters should not be determined
automatically, i.e., their name is not passed in
ParameterNameParameterNameParameterNameParameterNameparameterNameparameter_name, the corresponding parameters must contain
valid values and must not be set to 'auto'"auto""auto""auto""auto""auto". In contrast, if
these parameters are to be determined automatically, their values
are treated in the following way: If the optimization or the
(hysteresis) contrast is to be determined automatically, i.e.,
ParameterNameParameterNameParameterNameParameterNameparameterNameparameter_name contains the value 'optimization'"optimization""optimization""optimization""optimization""optimization" or
'contrast'"contrast""contrast""contrast""contrast""contrast" ('contrast_hyst'"contrast_hyst""contrast_hyst""contrast_hyst""contrast_hyst""contrast_hyst"), the values passed in
OptimizationOptimizationOptimizationOptimizationoptimizationoptimization and ContrastContrastContrastContrastcontrastcontrast are ignored. In
contrast, if the maximum number of pyramid levels or the minimum
contrast is to be determined automatically, i.e.,
ParameterNameParameterNameParameterNameParameterNameparameterNameparameter_name contains the value 'num_levels'"num_levels""num_levels""num_levels""num_levels""num_levels" or
'min_contrast'"min_contrast""min_contrast""min_contrast""min_contrast""min_contrast", you can let HALCON determine suitable
values and at the same time specify an upper or lower boundary,
respectively:
If the maximum number of pyramid levels should be specified in
advance, NumLevelsNumLevelsNumLevelsNumLevelsnumLevelsnum_levels can be set to the particular value. If
in this case ParametersParametersParametersParametersparametersparameters contains the value
'num_levels'"num_levels""num_levels""num_levels""num_levels""num_levels", the computed number of pyramid levels is at
most NumLevelsNumLevelsNumLevelsNumLevelsnumLevelsnum_levels. If NumLevelsNumLevelsNumLevelsNumLevelsnumLevelsnum_levels is set to
'auto'"auto""auto""auto""auto""auto" (or 0 for backwards compatibility), the
number of pyramid levels is determined without restrictions as large
as possible.
If the minimum contrast should be specified in advance,
MinContrastMinContrastMinContrastMinContrastminContrastmin_contrast can be set to the particular value. If in this
case ParametersParametersParametersParametersparametersparameters contains the value 'min_contrast'"min_contrast""min_contrast""min_contrast""min_contrast""min_contrast",
the computed minimum contrast is at least MinContrastMinContrastMinContrastMinContrastminContrastmin_contrast. If
MinContrastMinContrastMinContrastMinContrastminContrastmin_contrast is set to 'auto'"auto""auto""auto""auto""auto", the minimum contrast
is determined without restrictions.
If the user wishes to create a calibrated, deformable model
with create_planar_calib_deformable_modelcreate_planar_calib_deformable_modelCreatePlanarCalibDeformableModelCreatePlanarCalibDeformableModelCreatePlanarCalibDeformableModelcreate_planar_calib_deformable_model, the internal camera
parameters are needed for the correct estimation of the parameters in
ParameterValueParameterValueParameterValueParameterValueparameterValueparameter_value. The camera parameters can be provided by setting
GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name to 'cam_param'"cam_param""cam_param""cam_param""cam_param""cam_param" and providing the tuple containing
the camera parameters in GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value。
