Abstract
Panoramic image stitching with handling the parallax effect for the known world model
Incoming article date: 25.09.2013The short review of existing panoramic systems are given. The limits of such systems doesn't allow to form a panoramic video with dealing the parallax effect in real-time systems. The presented algorithm for forming a panoramic video is free of these disadvantages. An algorithm based on mathematical model of the round-view system that takes into account the location of cameras, their intrinsic parameters and model of the world. The algorithm includes following chain of coordinate transformation: from panoramic image coordinates to spherical coordinates and to Cartesian world coordinate system, from world coordinates to camera coordinate system and to input image coordinates. Geometric distortion of camera is dealt. Model of the world is represented as spherical and a hemispherical surfaces.
