摘要
本文进一步研究了双对极心约束条件,使双对极心约束条件由一个81项4元8次方程简化为54项4元6次方程,并用单纯形法求得问题的最优解,实现了F阵的高速度、高精度估计。实验结果表明,本文所提供的方法不仅能高精度地估计出F阵,而且对极点稳定性也有较大改善。
In this paper, the two-epipole constraint is studied further. The nonlinear constraint equation of degree 8 in 4 unknowns is reduced to a nonlinear equation of degree 6 in 4 unknowns. The optimal solution and robust F-matrix can be obtained by using simplex algorithm. Experimental results show that our method performs very well in terms of robustness to outliers and noises, and the fundamental matrix with high accuracy could be found.
