| Abstract |
In the field of machine vision, the
multi‐solution problem of the perspective‐three‐point
(P3P) camera pose estimation problem has been widely
researched. Many researchers have tried to find unique
solutions that will enable the use of the P3P method in
practical applications such as the calibration of external
parameters of a camera. Gao found a special case that is
very simple and intuitive, but can only be used for a
camera with a very large field of view. Therefore, it did
not attract much attention. The purpose of this study
was to analyse Gao’s special case and use it for calibrating
the external parameters of an omnidirectional camera,
which is used widely because of its very large field of
view. We first verify Gao’s special case and extend its
application. We then propose an iterative method for
finding the unique solution. After this, we perform a
simulation experiment to determine the effect of the
configuration of the three control points on the accuracy
of the unique solution. Finally, we use an application to
examine the efficiency of the method. |
