Research on image processing of the three-dimensional image of panoramic annular lens

Abstract

Panoramic annular lens(PAL) is based on the principle of flat cylinder perspective(FCP),it images the three-dimensional space around its axis onto a two-dimensional annular space.For the principle it based on is FCP,which is different from central convergence perspective(CCP),the way human use to view the world.So the image of PAL doesn′t suit with our human, thus limits the usage of PAL,In this article,a new image process method is provided by the method of changing the principle of FCP to CCP,and expands the use of PAL into the three-dimensional space,makes it possible to the fields of endoscope,navigation,robot vision and large-scale inspection.
