Representation of rotations by unit quaternions Ultramicroscopy, 1990, 33, 209-213<br /> <br /> == Abstract ==<br /> <br /> A closed form solution by Horn of an absolute orientation problem in photogrammetry and robotics entails the equivalent<br /> expression of rotation matrices by unit quaternions [B.K.P. Horn, J. Opt. Soc. Am. 4 (1987) 629]. Such representation by<br /> quaternions offers practical advantages in electron microscopy of macromolecular structures, where rotation angles must also<br /> be determined by optimisation techniques.<br /> <br /> == Keywords ==<br /> <br /> Angular representation, Euler angles, Rotation matrix<br /> <br /> == Links ==<br /> <br /> == Related software ==<br /> <br /> == Related methods ==<br /> <br /> == Comments ==</div>
