Method and optical system for detecting a pupil of an eye located within a detection area using a machine learning algorithm and a data glasses system comprising the optical system

Abstract

The invention relates to a method for detecting a pupil (4) of an eye (2) located in a detection area (208), comprising: deflecting a laser beam (206) into a beam direction (θ, θ) that is variable in at least one dimension, in particular in two dimensions; scanning the detection area (208) by varying the beam direction (θ, θ); detecting an amplitude value of scattered light (210) of the laser beam (206) emitted into the detection area (208) onto the eye (2) by means of a detector (212), wherein the pupil (2) is detectable depending on the amplitude value and the associated beam direction (θ, θ); Providing the detected amplitude value and the associated radiation direction (Δ, Δ) or a group of amplitude values ​​with associated radiation directions (Δ, Δ)) to a machine learning algorithm (214), wherein the detected amplitude value and the associated emission direction (θ, θ) or the group of amplitude values ​​with associated emission directions (θ, θ) is iteratively provided to the algorithm (214), for example, immediately after detection (106); wherein the pupil (4) is detected by means of the algorithm (214) depending on the iteratively provided amplitude value and the associated emission direction (θ, θ) or the group of amplitude values ​​with associated emission directions (θ, θ). The invention further relates to an optical system (200) configured to carry out the method and to data glasses comprising the optical system (200).
