Detailed Description

Generated from:  MR::MultiwayICP

This class allows you to register many objects having similar parts
and known initial approximations of orientations/locations using
Iterative Closest Points (ICP) point-to-point or point-to-plane algorithms

Constructor & Destructor Documentation

__init__()

None meshlib.mrmeshpy.MultiwayICP.__init__	(		self,
		Vector_MeshOrPointsXf_ObjId	objects,
		MultiwayICPSamplingParameters	samplingParams )

Member Function Documentation

calculateTransformations()

Vector_AffineXf3f_ObjId meshlib.mrmeshpy.MultiwayICP.calculateTransformations	(		self,
		func_bool_from_float	cb = 'MR::ProgressCallback{}' )

runs ICP algorithm given input objects, transformations, and parameters;
\\return adjusted transformations of all objects to reach registered state
the transformation of the last object is fixed and does not change here

calculateTransformationsFixFirst()

Vector_AffineXf3f_ObjId meshlib.mrmeshpy.MultiwayICP.calculateTransformationsFixFirst	(		self,
		func_bool_from_float	cb = 'MR::ProgressCallback{}' )

runs ICP algorithm given input objects, transformations, and parameters;
\\return adjusted transformations of all objects to reach registered state
the transformation of the first object is fixed and does not change here

devEnableIndependentEquationsMode()

None meshlib.mrmeshpy.MultiwayICP.devEnableIndependentEquationsMode	(		self,
		bool	on )

devIndependentEquationsModeEnabled()

bool meshlib.mrmeshpy.MultiwayICP.devIndependentEquationsModeEnabled

(

self

)

if in independent equations mode - creates separate equation system for each object
otherwise creates single large equation system for all objects

getCascadeIndexer()

IICPTreeIndexer meshlib.mrmeshpy.MultiwayICP.getCascadeIndexer

(

self

)

returns pointer to class that is used to navigate among layers of cascade registration
if nullptr - cascade mode is not used

getMeanSqDistToPlane()

float meshlib.mrmeshpy.MultiwayICP.getMeanSqDistToPlane	(		self,
		std_optional_double	value = 'std::optional<double>{}' )

computes root-mean-square deviation from points to target planes
or the standard deviation from given value if present

getMeanSqDistToPoint()

float meshlib.mrmeshpy.MultiwayICP.getMeanSqDistToPoint	(		self,
		std_optional_double	value = 'std::optional<double>{}' )

computes root-mean-square deviation between points
or the standard deviation from given value if present

getNumActivePairs()

int meshlib.mrmeshpy.MultiwayICP.getNumActivePairs

(

self

)

computes the number of active point pairs

getNumSamples()

int meshlib.mrmeshpy.MultiwayICP.getNumSamples

(

self

)

computes the number of samples able to form pairs

getPairsPerLayer()

Vector_Vector_Vector_ICPGroupPairs_Id_ICPElemtTag_Id_ICPElemtTag_int meshlib.mrmeshpy.MultiwayICP.getPairsPerLayer

(

self

)

returns all pairs of all layers

getParams()

ICPProperties meshlib.mrmeshpy.MultiwayICP.getParams

(

self

)

getStatusInfo()

str meshlib.mrmeshpy.MultiwayICP.getStatusInfo

(

self

)

returns status info string

resamplePoints()

bool meshlib.mrmeshpy.MultiwayICP.resamplePoints	(		self,
		MultiwayICPSamplingParameters	samplingParams )

select pairs with origin samples on all objects

setParams()

None meshlib.mrmeshpy.MultiwayICP.setParams	(		self,
		ICPProperties	prop )

tune algorithm params before run calculateTransformations()

setPerIterationCallback()

None meshlib.mrmeshpy.MultiwayICP.setPerIterationCallback	(		self,
		func_void_from_int	callback )

sets callback that will be called for each iteration

updateAllPointPairs()

bool meshlib.mrmeshpy.MultiwayICP.updateAllPointPairs	(		self,
		func_bool_from_float	cb = 'MR::ProgressCallback{}' )

in each pair updates the target data and performs basic filtering (activation)
in cascade mode only useful for stats update
