We present a novel panoramic imaging system which uses a curved mirror as a simple optical attachment to a ﬁsheye lens. When compared to existing panoramic cameras, our “cata-ﬁsheye” camera has a simple, compact and inexpensive design, and yet yields high optical performance. It captures the desired panoramic ﬁeld of view in two parts. The upper part is obtained directly by the ﬁsheye lens and the lower part after reﬂection by the curved mirror. These two parts of the ﬁeld of view have a small overlap that is used to stitch them into a single seamless panorama. The cata-ﬁsheye concept allows us to design cameras with a wide range of ﬁelds of view by simply varying the parameters and position of the curved mirror. We provide an automatic method for the one-time calibration needed to stitch the two parts of the panoramic ﬁeld of view. We have done a complete performance evaluation of our concept with respect to (i) the optical quality of the captured images, (ii) t...
