Abstract

A closed form solution by Horn of an absolute orientation problem in photogrammetry and robotics entails the equivalent expression of rotation matrices by unit quaternions [B.K.P. Horn, J. Opt. Soc. Am. 4 (1987) 629]. Such representation by quaternions offers practical advantages in electron microscopy of macromolecular structures, where rotation angles must also be determined by optimisation techniques.
