Super-Wide-Angle Imaging by Synthesizing Images

Abstract

Synthesizing left and right images is one of the popular methods used to get a wide-angle image, and this synthesis has conventionally been done by putting two images side by side. The conventional technique thus restricted the arrangement of the cameras and targets. This paper proposes a new method for acquiring a super-wide-angle image by synthesizing images. Left and right rectangular images are transformed into trapezoial images, and the transform formula is derived from relation between the position of the cameras and the target. This method enables the cameras to be set up anywhere and it provides an image nearly twice as wide as the one obtained with a camera, an image easy to see in perspective. This paper also shows the result of a computer simulation for this method.
