Abstract

In this paper, an extended P3P (Perspective Three Points) problem is investigated. It is formulated as fitting three moving vertices along their associated optical rays to a known triangle structure. This allows the three optical rays to come from one, two or three cameras respectively. The classical P3P problem for only single camera is considered as a special case of the extended P3P problem. An analysis on these different cases is given in a uniform way. Experiments with simulated data show the effectiveness of the approach.
