WebConverting fisheye images to other projections. Spherical Projections (Stereographic and Cylindrical) Written by Paul Bourke EEG data courtesy of Dr Per Line December 1996, Updated December 1999 Stereographic. The stereographic projection is one way of projecting the points that lie on a spherical surface onto a plane. WebIn fisheye image, when an object moves in XY plane at the same Z, its appearance changes as well. CNN is not immediately compatible with such a fisheye raw image. One way is to convert it into a cylindrical view. An object’s side and appearance remain the same as long as the $\rho$ distance keeps the same.
