sed-form solution of absolute orientation using unit quaternions

BKP Horn - JOSA A, 1987 - opticsinfobase.org
Finding the relationship between two coordinate systems using pairs of measurements of
the coordinates of a number of points in both systems is a classic photogrammetric task. It
finds applications in stereophotogrammetry and in robotics. I present here a closed-form ...

[LIBRO] Quaternions and rotation sequences

JB Kuipers - 1999 - emis.ams.org
Abstract. In this paper we introduce and define the quaternion; we give a brief introduction to
its properties and algebra, and we show, what appears to be, its primary application—the
quaternion rotation operator. The quaternion rotation operator competes with the ...

On quaternions and octonions: their geometry, arithmetic, and symmetry, AK

JH Conway, DA Smith, AK Peters - 2003 - Citeseer
Abstract Conway and Smith's book is a wonderful introduction to the normed division
algebras: the real numbers (R), the complex numbers (C), the quaternions (H), and the
octonions (O). The first two are well-known to every mathematician. In contrast, the ...

[HTML] Quaternions and matrices of quaternions

F Zhang - Linear algebra and its applications, 1997 - Elsevier
We give a brief survey on quaternions and matrices of quaternions, present new proofs for
certain known results, and discuss the quaternionic analogues of complex matrices. The
methods of converting a quaternion matrix to a pair of complex matrices and homotopy ...

Estimating 3-D location parameters using dual number quaternions

MW Walker, L Shao, RA Volz - CVGIP: image understanding, 1991 - Elsevier
Abstract This paper describes a new algorithm for estimating the position and orientation of
objects. The problem is formulated as an optimization problem using dual number
quaternions. The advantage of using this representation is that the method solves for the ...
