Passive stereoscopic panomorph system

Abstract

In the last decade, wide-angle stereoscopic systems using fisheye lenses have been proposed but the compromise made to obtain a large field of view is low resolution and high distortion resulting in imprecise depth estimation of objects in a 3D scene. High and non-uniform distortion, especially in the azimuthal direction, is often considered as a weakness of panoramic lenses because it is sometimes difficult to compensate for by image processing. The aim of this paper is to present an alternative to existing stereoscopic panoramic systems by taking advantage of nonuniform distortion and anamorphosis in Panomorph lenses. There are many challenges related to this project such as the calibration of the system and the creation of a 3D depth estimation algorithm that suits the resolution of the different areas in the images. This paper presents different configurations of two Panomorph lenses within a stereoscopic device and a study of specific parameters to highlight their impact on the quality of 3D reconstruction of an object in a scene. Finally, an overview of future work is presented.
