Abstract
This technical report complements the results recently presented in [1] showing that they can be extended to define an efficient and robust method to determine the rotation matrix nearest to an arbitrary 3 × 3 matrix. This problem arises in different areas of robotics that range from the simple case in which we have to restore the orthogonality of a noisy rotation matrix to point-cloud registration or hand-eye calibration. We show that the new method compares favorably with the classical approaches to address this problem and also with more recent methods
