Differential Methods in Catadioptric Sensor Design with Applications to Panoramic Imaging

摘要

We discuss design techniques for catadioptric sensors that realize givenprojections. In general, these problems do not have solutions, but approximatesolutions may often be found that are visually acceptable. There are severalmethods to approach this problem, but here we focus on what we call the``vector field approach''. An application is given where a true panoramicmirror is derived, i.e. a mirror that yields a cylindrical projection to theviewer without any digital unwarping.
