calcAlignmentError()

double ConsistencyTest::calcAlignmentError	(	std::map< unsigned, unsigned > &	matched_planes,
		Eigen::Matrix4f &	rigidTransf
	)

Calculate the alignment error between two sets of matched planes. The input rigid transformation "se3rigidTransfInv" is used to project the centroids of one set of planes into their matched planes and returns the sum of cuadratic distances

getRTwithModel()

Eigen::Matrix4f ConsistencyTest::getRTwithModel

(

std::map< unsigned, unsigned > &

matched_planes

)

Return the estimated rigid transformation which aligns two matched subgraphs (i.e. neighborhoods of planes). This function iteratively minimizes the alignment error of the matched planes wrt the rigid transformation.

initPose()

Eigen::Matrix4f ConsistencyTest::initPose

(

std::map< unsigned, unsigned > &

matched_planes

)

Return an initial guess for the rigid transformation which aligns two matched places. The translation is calculated from the planes centroids and the rotation from the alignment of the plane's normals.

float trans_error = fabs(-PBMTarget.vPlanes[it->second].d + translation.dot(PBMTarget.vPlanes[it->second].v3normal) + PBMSource.vPlanes[it->first].d);

initPose2D()

Eigen::Matrix4f ConsistencyTest::initPose2D

(

std::map< unsigned, unsigned > &

matched_planes

)

Return an initial guess for the rigid transformation which aligns two matched places. The translation is calculated from the planes centroids and the rotation from the alignment of the plane's normals. A planar movement is assumed (wheeled robot)
