A Study on the P3P Problem

摘要

In this paper, we focus on the number of solution for the Perspective-Three-point problem (P3P) in some geometrical constraints of 3 points, which is a common problem in applied mathematics and computer vision. We use Wu's zero decomposition method to find a complete triangular decomposition of a practical configuration for the P3P problem. By the Wu's method, we also obtain some sufficient conditions under which there are multi-solution for the P3P problem.
