Constructor & Destructor Documentation

lslgeneric::NDTMatcherD2D_2D::NDTMatcherD2D_2D	(	bool	_isIrregularGrid,
		bool	useDefaultGridResolutions,
		std::vector< double >	_resolutions
	)		`[inline]`

parametrized constructor. A default set is (false,false,true,empty_vector). parameters are:

Parameters:

_isIrregularGrid	--- experimental single pass through an irregular grid. also unstable
useDefaultGridResolutions	--- if set, the following parameter is set to a preset value
_resolutions	--- if previous bool is not set, these are the resolutions (in reverse order) that we will go through

	)

Register two point clouds. Use only 2D rotations This method builds an NDT representation of the "fixed" point cloud and uses that for registering the "moving" point cloud.

Parameters:

fixed	Reference data. NDT structure is built for this point cloud.
moving	The output transformation registers this point cloud to `fixed`.
T	This is an input/output parameter. The initial value of `T` gives the initial pose estimate of `moving`. When the algorithm terminates, `T` holds the registration result.

		bool	useInitialGuess = `false`
	)

Registers a two ndt maps using only 2D rotation/translation.

Parameters:

fixed	Reference data.
moving	The output transformation registers this point cloud to `fixed`.
T	This is an input/output parameter. The initial value of `T` gives the initial pose estimate of `moving`. When the algorithm terminates, `T` holds the registration result.
