(EN) APPARATUS AND METHOD FOR ACQUIRING UNIFORM-RESOLUTION PANORAMIC IMAGES
(FR) APPAREIL ET PROCEDE D'ACQUISITION D'IMAGES PANORAMIQUES A RESOLUTION UNIFORME
Abrégé
(EN)
A panoramic imaging system is constructed to acquire panoramic images of a very large field of view. The field of view ranges from being nearly hemispherical, to being omni directional with some parts occluded. The panoramic imaging system is comprised of multiple imaging sensors, each imaging different parts of the field of view. The panoramic image is constructed by mosaicing the images taken by different sensors that share a common viewpoint. The resolution across the entire panoramic image is substantially the same. Specific embodiments of the camera provide specific combinations of features, such as different visual fields.
(FR)
Un système d'imagerie panoramique est conçu pour acquérir des images panoramiques d'un très grand angle de champ. L'angle de champ est compris dans une fourchette allant d'un angle sensiblement hémisphérique à un angle omnidirectionnel avec certaines parties occluses. Ce système d'imagerie panoramique est composé de multiples capteurs d'imagerie, chacun de ces capteurs produisant l'image de différentes parties de l'angle de champ. L'image panoramique est construite par assemblage sous forme d'une mosaïque des images prise par les différents capteurs qui partagent un point de vue commun. La résolution sur la totalité de l'image panoramique est sensiblement la même. Dans des modes de réalisation spécifiques, la caméra dispose de combinaisons spécifiques de caractéristiques, par exemple de différents champs visuels.
