Nevertheless, the dimensional difference of points and lines and the inconsistency of their methods of representation result in low calculation efficiency. In this paper, it is proposed that three-dimensional points and four-dimensional lines are uniformly represented by Plücker coordinates to achieve integrated coordinate transformation. According to the geometric conditions that lines intersect lines and planes intersect planes, a relative orientation model based on pointline via Plücker coordinates (P-LPRO) is established, and the error equation is linearized by the least-squares method. Experimental results show that the integrated adjustment solution of P-LPRO is more accurate than the traditional method and can achieve faster convergence speed.

Relative orientation dependent on dual quaternions / Qing H. Sheng in Photogrammetric record, vol 30 n° 151 (September - November 2015)

Dual quaternions are used to express a unified description of the relative position and orientation of two images in a stereopair. The coplanarity condition equation and its linearised model based on dual quaternions are established. According to the principle of least squares adjustment with constraints, a dual quaternion can be identified and the relative-orientation parameters can then be obtained by a non-linear transformation of the components of the dual quaternion. Experimental results show that the proposed approach is feasible and more reliable and efficient than the conventional approach based on Euler angles.
