Title
(EN) TRACKING-BASED ILLUMINATION CONTROL SYSTEM
(FR) SYSTÈME DE COMMANDE D'ÉCLAIRAGE BASÉ SUR LA POURSUITE
Abstract
(EN)
A Light Adjustable Lens (LAL) Tracker comprises an Imaging System, for creating a LAL image by imaging a LAL implanted into an eye; and an Image Recognition System, coupled to the Imaging System, for determining a disk cross-correlator with the LAL image; determining an edge cross-correlator with the LAL image; and determining a LAL position by determining a combined cross-correlator from the disk cross-correlator and the edge cross-correlator. A Tracking-based Illumination Control System comprises the LAL Tracker for tracking a LAL implanted in an eye, including an Imaging System, and an Image Recognition System; and an Illumination Controller, coupled to the LAL Tracker, configured for determining a LAL misalignment factor, corresponding to a LAL misalignment that characterizes a misalignment of the LAL position with a LAL illumination pattern, and generating an illumination control signal in relation to the determined LAL misalignment factor.
(FR)
Un dispositif de suivi de lentille à réglage de lumière (LAL) comprend un système d'imagerie, pour créer une image LAL par imagerie d'une LAL implantée dans un oeil; et un système de reconnaissance d'image, couplé au système d'imagerie, pour déterminer un inter-corrélateur de disque avec l'image LAL; déterminer un inter-corrélateur de bord avec l'image LAL; et déterminer une position LAL par détermination d'un inter-corrélateur combiné à partir de l'inter-corrélateur de disque et de l'inter-corrélateur de bord. Un système de commande d'éclairage basé sur le suivi comprend le dispositif de suivi LAL pour suivre une LAL implantée dans un oeil, comprenant un système d'imagerie, et un système de reconnaissance d'image; et un dispositif de commande d'éclairage, couplé au dispositif de suivi LAL, configuré pour déterminer un facteur de désalignement de LAL, correspondant à un désalignement de LAL qui caractérise un désalignement de la position de LAL avec un diaramme d'éclairage LAL, et générer un signal de commande d'éclairage se rapportant au facteur de désalignement de LAL déterminé.
