摘要
本文研究了计算机视觉中P4P问题的多解问题,运用几何方法,分析了P4P问题的多解现象,获得了P4P问题存在5个解的必要条件.
The perspective-n-point(PnP) problem is to find the position and orientation of a camera with respect to a scene object from n correspondence points. In this paper, we study the multi-solution phenomenon for the P4P problem by using geometric method and give some necessary conditions under which there are five positive solutions for the P4P problem.
