Abstract--Dual-camera systems have been widely used in
surveillance because of the ability to explore the wide field of view
(FOV) of the omnidirectional camera and the wide zoom range
of the PTZ camera. Most existing algorithms require a priori
knowledge of the omnidirectional camera's projection model
to solve the nonlinear spatial correspondences between the two
cameras. To overcome this limitation, two methods are proposed:
1) geometry and 2) homography calibration, where polynomials
with automated model selection are used to approximate the
camera's projection model and spatial mapping, respectively. The
proposed methods not only improve the mapping accuracy by
reducing its dependence on the knowledge of the projection model
but also feature reduced computations and improved flexibility in
adjusting to varying system configurations. Although the fusion of
multiple cameras has attracted increasing attention, most existing
