Title
(EN) PANORAMIC IMAGING APPARATUS
(FR) DISPOSITIF D'IMAGERIE PANORAMIQUE
Abstract
(EN)
A system is disclosed for capturing super wide-angle panoramic images. In particular, a two-reflector system is disclosed which is substantially self-correcting in which optical aberrations are substantially eliminated, such as field curvature, astigmatism and the like. Moreover, the super wide-angle panoramic imaging apparatus of the invention captures a super-wide field of view from a substantially single reference viewpoint. The invention provides a substantially compact viewpoint, while also having a substantially flat and stigmatic image plane, in the context of a super wide-angle panoramic system. Devices and methods for capturing panoramic images of super wide-angle scenes are provided. In a particular embodiment of the invention, two reflectors are provided (e.g., one a hyperboloidal mirror, the other a concave ellipsoidal or spherical mirror), a relay system (e.g., optics such as a mirror, a lens, a pinhole and the like) and an image sensor (e.g., an electronic photo-sensor, a film and the like).

L'invention concerne un système permettant de saisir des images panoramiques en super grand-angle. L'invention concerne en particulier un système à double réflecteur qui est sensiblement auto-correcteur, et permet d'éliminer sensiblement les aberrations optiques telles que la courbure de champ, l'astigmatisme etc. Ce système d'imagerie panoramique à super grand-angle couvre en outre un champ extra large à partir d'un point de vue de référence sensiblement unique. Il offre un point de vue sensiblement compact, et présente en outre un plan image sensiblement plat et stigmatique, dans le contexte d'un système panoramique à super grand angle. L'invention concerne en outre des dispositifs et des procédés permettant de saisir des images panoramiques en super grand-angle. Dans une forme d'exécution particulière, le système comprend deux réflecteurs (p. ex. un miroir hyperbolique et un miroir concave ellipsoïdal ou sphérique), un système de relais (p. ex. des dispositifs optiques tels que miroir, lentille, sténopé, etc.) et un capteur d'image (p. ex. un capteur photo-électronique, un film etc.).
