Member Function Documentation

void LandmarkDB::addLandmark	(	uint	snum,
		rutz::shared_ptr< Landmark >	lmk
	)			[inline]

add landmark to segment snum

Definition at line 242 of file LandmarkDB.H.

References ASSERT.

void LandmarkDB::build	(	std::vector< rutz::shared_ptr< VisualObject > > &	inputVO,
		std::vector< Point2D< int > > &	objOffset,
		uint	fNum,
		uint	currSegNum,
		rutz::shared_ptr< VisualObject >	scene
	)

build the landmarkDB by inputting the Visual Object, etc information

build and finishBuild are 2 functions that needs to be called to create landmarks. build is called repeatedly every time new evidence comes in. finishBuild is called at the end to wrap up the process. It prunes all the ephemeral landmarks.

Usually build and actual use are done on seperate session.

Before use, need to call setSession function to get the landmarks sorted and all the session related info reset
