Paper Abstract

A design method for the distortionless catadioptric panoramic imaging system is proposed in this paper. The panoramic system mainly consists of two parts, a reflecting surface system with relay lens and a CCD camera. A mapping relationship between the real image plane and the projection surface is established to acquires low distorted imaging features easily. And the design of freeform surface is applied to the reflecting surfaces to correct distortion. After iteratively optimize the freeform surfaces, the image quality is gradually improved. The simulation results show that compared with traditional system, the new freeform surface system has simple design, attaining higher performance and has the advantage of small scene distortion and making the image more suitable and convenient for observing.
