Title
(EN) HIGH DEFINITION, LARGE CAPTURE VOLUME, CAMERA ARRAY SYSTEM
(FR) SYSTÈME DE RÉSEAU DE CAMÉRAS À HAUTE DÉFINITION ET À GRAND VOLUME DE CAPTURE
Abstract
(EN)
The technology described herein can be embodied in a method that includes capturing, using a first array of multiple image acquisition devices, a first set of images of a scene, and capturing, using a second array of multiple image acquisition devices, a second set of images of the scene. The devices of the first array are each focused at a first distance, and the devices of the second array are each focused at a second distance. The method also includes identifying a first image and a second image in the first and second sets of images, respectively, to include a feature of interest. The method further includes determining a focal score for each of the first and second images, selecting one of the images based on a comparison of the corresponding focal scores, and initiating an authentication process based on the selected image.

La technologie décrite dans la présente invention peut être mise en œuvre dans un procédé qui consiste à capturer, à l'aide d'un premier réseau de multiples dispositifs d'acquisition d'image, un premier ensemble d'images d'une scène, et à capturer, à l'aide d'un second réseau de multiples dispositifs d'acquisition d'image, un second ensemble d'images de la scène. Les dispositifs du premier réseau sont chacun focalisés à une première distance, et les dispositifs du second réseau sont chacun focalisés à une seconde distance. Le procédé comprend également l'identification d'une première image et d'une seconde image dans les premier et second ensembles d'images, respectivement, pour inclure une caractéristique d'intérêt. Le procédé comprend en outre la détermination d'un score focal pour chacune des première et seconde images, la sélection d'une des images sur la base d'une comparaison des scores focaux correspondants, et l'initiation d'un processus d'authentification sur la base de l'image sélectionnée.
