Abstract--Wide field of view (FOV) and high-resolution image acquisition is highly
desirable in many vision-based applications. Several systems have reported the
use of reflections off mirror pyramids to capture high-resolution, single-viewpoint,
and wide-FOV images. Using a dual mirror pyramid (DMP) panoramic camera as
an example, in this paper, we examine how the pyramid geometry, and the
selection and placement of imager clusters can be optimized to maximize the
overall panoramic FOV, sensor utilization efficiency, and image uniformity. The
analysis can be generalized and applied to other pyramid-based designs.
Index Terms--Panoramic camera, mirror pyramids, omnidirectional imaging, and
catadioptric systems.
