overrideprotectedvirtual

Add visual residuals to a CERES problem for a motion only BA.

Parameters

problem	The CERES problem to which the residuals will be added.
loss_function	The loss function to be used for the residuals.
frame	The frame to which the residuals will be added.
cloud_to_optimize	The landmarks belonging to the frame.

Returns: The number of residuals added.

Implements isae::AOptimizer.

◆ marginalize()

bool isae::BundleAdjustmentCERESAnalytic::marginalize	(	std::shared_ptr< Frame > &	frame0,
		std::shared_ptr< Frame > &	frame1,
		bool	enable_sparsif
	)

overridevirtual

Marginalization of a frame and its landmarks.

Parameters

frame0	The frame to marginalize.
frame1	The frame to keep connected to frame0.
enable_sparsif	Whether to enable sparsification (default is false).

Perform all the marginalization steps for a given frame. A marginalization object deals with all these steps

Reimplemented from isae::AOptimizer.

◆ marginalizeRelative()

Eigen::MatrixXd isae::BundleAdjustmentCERESAnalytic::marginalizeRelative	(	std::shared_ptr< Frame > &	frame0,
		std::shared_ptr< Frame > &	frame1
	)

overridevirtual

Marginalization of all the landmarks linked to two frame and computation of the information matrix of the relative pose.

Parameters

frame0	The first frame to marginalize.
frame1	The second frame to marginalize.

Returns: The information matrix of the relative pose between frame0 and frame1.

This method computes the information matrix of the relative pose between two frames and marginalizes the landmarks linked to them. It uses NFR to extract a relative pose factor and to derive its information matrix.
