| Descripción: | Image’s registration includes 2D-2D, 3D-3D and 3D-2D registration. This paper only concentrates on the 2D-3D registration, the image’s attitude is represented by a rotation matrix R, while the position is a translation vector T. Traditional approaches mainly focus on points correspondences, and state-of-the-art approaches concentrate on high-order structures, i.e. lines, rectangle, parallelepiped etc. Mathematically, Most existing solutions adapt either linear optimization or iteration methods. However, they need the position, attitude initialization, which are not always available in real scene, and they do not guarantee to find global solutions. In this paper, instead of solving these polynomials directly, we introduce a novel approach ( say qLR ), which treat these multivariate polynomial equations as “monomials” and express R in a quaternion vision, resulting in dramatic decrement of the number of equations. |
