A catadioptric system is composed of a mirror and a perspective camera. Since the mirror is curved and the distance between the mirror and the camera is short, some parts of the panoramic image keep blurred. In this article, an optical approach of the panoramic system using a hyperbolic mirror is presented and its depth of field is analyzed. The impact of different parameters of mirror and camera on the quality of the panoramic image is researched and a valid method of choosing camera and mirror is presented. Finally, this article gives some possible perspectives based on these researches.
