Detailed Description

Multi marker that uses bundle adjustment to refine the 3D positions of the markers (point cloud).

This can be initialized by using e.g. MultiMarkerAverage class.

template<class M >

void alvar::MultiMarkerBundle::MeasurementsAdd	(	const std::vector< M > *	markers,
		const Pose &	camera_pose
	)		`[inline]`

Adds new measurements that are used in bundle adjustment.

Parameters:

markers	Vector of markers detected by MarkerDetector.
camera_pose	Current camera pose.

Examples:: SampleMultiMarkerBundle.cpp.

Definition at line 84 of file MultiMarkerBundle.h.

void alvar::MultiMarkerBundle::MeasurementsReset ( )

Resets the measurements and camera poses that are stored for bundle adjustment. If something goes from in optimization one will call this and acquire new measurements.

Examples:: SampleMultiMarkerBundle.cpp.

Definition at line 41 of file MultiMarkerBundle.cpp.

bool alvar::MultiMarkerBundle::Optimize	(	Camera *	_cam,
		double	stop,
		int	max_iter,
		Optimization::OptimizeMethod	method = `Optimization::TUKEY_LM`
	)

Runs the bundle adjustment optimization.

Parameters:

markers	Vector of markers detected by MarkerDetector.
camera_pose	Current camera pose.
max_iter	Maximum number of iteration loops.
method	The method that is applied inside optimization. Try Optimization::LEVENBERGMARQUARDT or Optimization::GAUSSNEWTON or Optmization::TUKEY_LM
