georegression.fitting.se.MotionSe3PointCrossCovariance_F32

All Implemented Interfaces:

georegression.fitting.MotionTransformPoint<georegression.struct.se.Se3_F32,georegression.struct.point.Point3D_F32>

public class MotionSe3PointCrossCovariance_F32
extends java.lang.Object
implements georegression.fitting.MotionTransformPoint<georegression.struct.se.Se3_F32,georegression.struct.point.Point3D_F32>

Finds the rigid body motion which minimizes the different between the two sets of associated points in 3D. Computes the quaternions directly in closed form.

The mean square error function that is minimized is:
f(q) = (1/N) sum( i=1:N , ||x_i - R(q_r)*p_i + q_t||² )
where q is the transformation parameterized with q_r quaternions and q_t translation, x is the set of 'to' points and p is the set of 'from' points.

The basic cross-covariance method sketch in Paul J. Besl and Neil D. McKay, "A Method for Registration of 3-D Shapes" IEEE Transactions on Pattern Analysis and Machine Intelligence, Vol 14, No. 2, Feb. 1992, is implemented below.
