Omnidirectional Video Camera

چکیده
Conventional video cameras have limited elds of view that make them restrictive in a variety of vision applications. There are several ways to enhance the eld of view of an imaging system. However, the entire imaging system must have a single eeective viewpoint to enable the generation of pure perspective images from a sensed image. A new camera with a hemispherical eld of view is presented. Two such cameras can be placed back-to-back without violating the single viewpoint constraint, to arrive at a truly omnidirec-tional sensor. Results are presented on the software generation of pure perspective images from an omnidirectional image, given any user-selected viewing direction and magniication. The paper concludes with a discussion on the spatial resolution of the proposed camera.

Video Completion for Generating Omnidirectional Video without Invisible Areas
Omnidirectional multi-camera systems cannot capture entire fields of view because of their inability to view areas directly below them. Such invisible areas in omnidirectional video decrease the resulting realistic sensation experienced when using a telepresence system. In this study, we generate omnidirectional video without invisible areas using an image completion technique. The proposed met...
متن کاملHigh-resolution Panoramic Movie Generation from Video Streams Acquired by an Omnidirectional Multi-camera System
Telepresence systems using an omnidirectional image sensor enable us to experience remote sites with rich sensation. An omnidirectional multi-camera system is more useful to acquire high-resolution omnidirectional images of outdoor scenes than a monocular camera system. However, exact calibration of the camera system is necessary to generate a panoramic movie. In this paper, we describe a panor...
متن کاملStabilizing Omnidirectional Videos Using 3D Structure and Spherical Image Warping
This paper addresses the problem of stabilizing spherical videos. Whereas various techniques have been proposed to stabilize conventional videos, this work is the first approach proposed for omnidirectional videos. We introduce a method for extracting the camera path and 3D information of the environment. A desired smooth stabilized path is obtained by modifying the original camera path. We pro...
متن کاملVisual tracking with omnidirectional cameras: an efficient approach
An effective technique for applying visual tracking algorithms to omnidirectional image sequences is presented. The method is based on a spherical image representation which allows taking into account the distortions and nonlinear resolution of omnidirectional images. Experimental results show that both deterministic and probabilistic tracking methods can effectively be adapted in order to robu...
