Web13 de jul. de 2010 · A fisheye lens allows an extremely wide field of view, nearly 180 degrees, but it also bends the light in order to fit it all on a square so you get an interesting effect where the edges become distorted and straight lines become curved. WebThe following presents one method by which two fisheye images, with sufficient apertures, can be combined to form one spherical (equirectangular) projection. It is one of two main approaches, this is a purely geometric algorithm, the alternative is to detect feature points between the two overlapping fisheye images and perform a warp/blend.
