Description
determine_ncc_model_paramsdetermine_ncc_model_paramsDetermineNccModelParamsDetermineNccModelParamsDetermineNccModelParamsdetermine_ncc_model_params determines certain parameters
of an NCC model automatically from the model image
TemplateTemplateTemplateTemplatetemplatetemplate. The parameters to be determined can be specified
with ParametersParametersParametersParametersparametersparameters. determine_ncc_model_paramsdetermine_ncc_model_paramsDetermineNccModelParamsDetermineNccModelParamsDetermineNccModelParamsdetermine_ncc_model_params can
be used to determine the same parameters that are determined
automatically when the respective parameter in
create_ncc_modelcreate_ncc_modelCreateNccModelCreateNccModelCreateNccModelcreate_ncc_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") and/or the angle step length
(ParametersParametersParametersParametersparametersparameters = 'angle_step'"angle_step""angle_step""angle_step""angle_step""angle_step"). 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.
determine_ncc_model_paramsdetermine_ncc_model_paramsDetermineNccModelParamsDetermineNccModelParamsDetermineNccModelParamsdetermine_ncc_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.
The input parameters (NumLevelsNumLevelsNumLevelsNumLevelsnumLevelsnum_levels, AngleStartAngleStartAngleStartAngleStartangleStartangle_start,
AngleExtentAngleExtentAngleExtentAngleExtentangleExtentangle_extent, and MetricMetricMetricMetricmetricmetric) have the same meaning as
in create_ncc_modelcreate_ncc_modelCreateNccModelCreateNccModelCreateNccModelcreate_ncc_model. The description of these parameters
can be looked up with this operator. These parameters are used
by determine_ncc_model_paramsdetermine_ncc_model_paramsDetermineNccModelParamsDetermineNccModelParamsDetermineNccModelParamsdetermine_ncc_model_params to calculate the parameters
to be determined in the same manner as in create_ncc_modelcreate_ncc_modelCreateNccModelCreateNccModelCreateNccModelcreate_ncc_model.
Note that in determine_ncc_model_paramsdetermine_ncc_model_paramsDetermineNccModelParamsDetermineNccModelParamsDetermineNccModelParamsdetermine_ncc_model_params the input
parameter NumLevelsNumLevelsNumLevelsNumLevelsnumLevelsnum_levels can also be determined automatically.
If this parameter should not be determined automatically, i.e.,
the name is not passed in ParametersParametersParametersParametersparametersparameters, the parameter must
contain a valid value and must not be set to 'auto'"auto""auto""auto""auto""auto". In
contrast, if the maximum number of pyramid levels is to be
determined automatically, i.e., ParametersParametersParametersParametersparametersparameters contains the
value 'num_levels'"num_levels""num_levels""num_levels""num_levels""num_levels", you can let HALCON determine a
suitable value and at the same time specify an upper boundary:
If the maximum number of pyramid levels should be specified in
advance, the input parameter 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, the number of pyramid levels
is determined without restrictions as large as possible.
