Returns the concrete back-end identifier (one of Type).

Implements rtabmap::Optimizer.

◆ optimizeBA()

virtual std::map< int, Transform > rtabmap::OptimizerCVSBA::optimizeBA	(	int	rootId,
		const std::map< int, Transform > &	poses,
		const std::multimap< int, Link > &	links,
		const std::map< int, std::vector< CameraModel > > &	models,

		const std::map< int, std::map< int, FeatureBA > > &	wordReferences,
		BAOutliers *	outliers = `0`
	)

virtual

Bundle adjustment: jointly refine poses and 3D points (back-end-level entry point).

Concrete subclasses (g2o, Ceres, cvsba) override this; the base implementation errors out. The other optimizeBA() overloads ultimately funnel here.

Parameters

rootId	Pose to hold fixed. If negative, ALL poses other than the (positive) lowest id are held fixed.
poses	Initial pose estimates keyed by frame id.
links	Edges used to define the BA problem topology.
models	Camera model(s) per frame; for stereo, `Tx` must be set on the model (= -baseline*fx). Multi-camera rigs have multiple entries per frame.
points3DMap	In/out: world 3D points keyed by word id; refined on return.
wordReferences	Observations: `<wordId, <frameId, FeatureBA>>`. See FeatureBA.
outliers	Optional output: word ids dropped by the back-end's outlier rejection.

Returns: Refined poses, or empty on failure.
