“…But spatially seamless video presentation is needed when the purpose is to familiarize humans with environments. On the other hand, imaging equipment with sophisticated optical systems includes fisheye lenses [7], Hyper Omni Vision [8], and PALs (Panoramic Annular Lenses) [9,10]. In image stitching, multiple images are acquired by a rotating camera [5] or by multiple cameras [6], and overlapping images of the same scene are arranged so as to generate a single wide-field image.…”

“…In this case, however, the arrangement of overlapping images requires special processing such as mutual calibration of multiple cameras. On the other hand, imaging equipment with sophisticated optical systems includes fisheye lenses [7], Hyper Omni Vision [8], and PALs (Panoramic Annular Lenses) [9,10]. These are lenses that can acquire omnidirectional scenes by a single camera.…”

SUMMARY Video surveillance using intelligent camera systems is widely used in many fields such as traffic control, driving assistance, and surgery. But image acquisition of a large field of view for video surveillance makes infeasible the use of multiple camera systems or mechanically controlled cameras. To solve this problem, an omnidirectional camera system using a panoramic annular lens may be used, with many advantages such as compactness and the lack of a need for calibration. Nevertheless, the low spatial resolution of the angle of elevation for the vertical direction of images captured using PAL may incur drawbacks such as quality degradation of images after panoramic expansion. To overcome these disadvantages, a high‐quality panoramic image generation method is required. Therefore, we propose a high‐quality panoramic image generation method using multiple panoramic annular lens images. By synthesizing multiple PAL images at different zoom rates, we can obtain fine quality panoramic images.

The panoramic lens is a special kind of lens, which is applied to observe full view. In this letter, we theoretically present a panoramic lens (PL) using transformation optics method. The lens is designed with inhomogeneous and anisotropic constitutive parameters, which has the ability to gather light from all directions and confine light within the visual angle of observer. Simulation results validate our theoretical design.
