Integrated Relative Orientation Based on Point and Line Features via Plücker Coordinates
Relative orientation based on point and line features can significantly reduce the problems caused by single flight strip bending and strengthen geometric stability. 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.
