Abstract
A method and a system for realizing a virtual stereoscopic scene based on mapping are provided. The method comprises, acquiring a distance between an observer's two eyes E_R, a maximum convex displaying distance of a real screen N_R, a distance from the observer's eyes to the real screen Z_R, and a maximum concave displaying distance of the real screen F_R; calculating a parallax dN_R at N_R, and a parallax dF_R at F_R; acquiring a distance between a virtual single camera and a virtual near clipping plane N_V, and a distance between a virtual single camera and a virtual far clipping plane F_V; calculating a distance E_V between a left virtual camera and a right virtual camera, and asymmetric perspective projection parameters of the left virtual camera and the right virtual camera; performing a perspective projection transformation of scene content of the virtual single camera, and displaying a virtual stereoscopic scene.
