Paper Abstract

A new ultra-wide-angle projection function called fovea-stereographic is described and characterized by the relative relationship between the radial distortion level and the object field-of-view (FOV) angle, creating a high-resolution wide foveal image and adequate peripheral information to be processed within a limited computational time. The paper also provides the design results of an innovative fast fovea-stereographic fisheye lens system with a 170 deg of FOV that shows a more than 58.8% (100 deg) high-resolution central foveal image and at least 15% more peripheral information than any other light projection. Our lens distortion curve, in addition to its modulation transfer function, produces a high-resolution projection for real-time tracking and image transmission applications.
