Class AverageRotationMatrix_F64

java.lang.Object

georegression.transform.se.AverageRotationMatrix_F64

public class AverageRotationMatrix_F64
extends Object

Finds the average of a set of quaternions by using a modification of the method proposed in [1]. It works by finding the average rotation matrix then finds the best fit matrix in SO-3, see page 200 of [2].
