Abstract:
Systems and methods for panoramic imaging are disclosed herein. An exemplary system of the disclosed subject matter for panoramic imaging includes a fisheye lens, a mirror optically coupled to the fisheye lens, and a detector for capturing light incident on the fisheye lens and reflected from the mirror. In some embodiments, the mirror is a spherical mirror. In some embodiments, the mirror is positioned coaxially with regard to the fisheye lens. In some embodiments, the system is further configured to satisfy the following conditions that the upper angle of a desired field of view is equal to the upper angle of a field of view of the fisheye lens, the lower angle of the desired field of view is less than or equal to the lower angle of a field of view of the mirror, and the angle of overlap between the field of view of the mirror and the field of view of the fisheye lens is equal to the difference between the lower angle of the field of view of the fisheye lens and the upper angle of the field of view of the mirror.
