A novel car panoramic system based on catadioptric structure with dual-band operating mode

The 360 degrees panoramic system is a critical component of modern vehicle safety system. However, the existing fisheye lens design generates a large amount of barrel distortion, i.e. low resolution of the edge scene. Moreover, for night driving scenarios (the operating mode in the infrared band), the current conventional systems are lack of good performance capabilities. To solve these problems, in this work, we proposed a novel car panoramic system. We analyzed the general characteristics and implementation methods of the existing panoramic imaging system. The design of the novel car panoramic system is given. We also analyzed the tolerance of the whole system and designed its mechanical structure and coating. The MTF value of the proposed car panoramic system is higher than 42% in 90lp/mm for visible part and 50% in 20lp/mm for infrared part.
