Abstract
The defocus blur in catadioptric omni-directional imaging is caused by large apertures and mirror curvatures. This paper proposed a simple method to overcome the drawback. It analyzed the relationship between the blur and the light,constructed the mathmetic modle,estimated the degree of blur by the coded aperture, used specific deconvolution method to get the sharp image. The results of the omni-directional image show good quality and eliminate the defocus blur. The sharp image can be aplied for various catadioptric applications, including omni-directional monitoring systems, intelligent omni-directional systems and robotics.
