摘要： A system for determining one or more parameters of a user's eye includes a computing unit and a head-wearable device including a first camera having a field of view, and a non- transparent component. The first camera and the non-transparent component are arranged relative to each other so that at least a portion of the eye and at least a portion of the non- transparent component are expected to be in the field of view of the first camera when the user is wearing the head-wearable device. The computing unit implements a neural network and is configured to receive an image from the first camera, feed the image as an input into the neural network, and determine the one or more parameters as an output of the neural network.

摘要： A method (1000) for generating data suitable for determining a parameter of a human eye (H) having an eyeball (H 1 ) and an iris (H 2 ) defining a pupil (H 3 ) is presented. The method includes receiving a first image of the eye (H) for a first time (t 1 ) from a camera (14, 24) of known camera intrinsics defining an image plane (I p ), determining a first ellipse (E 1 ) in the first image, the first ellipse (E 1 ) at least substantially representing a border of the pupil (H 3 ) at the first time (t 1 ), using the first ellipse (E 1 ) to determine an orientation vector (η 1 ) of a first circle (C 1 ) and a first center line (L 1 ) on which a center of the first circle (C 1 ) is located, so that a projection of the first circle (C 1 ), in a direction parallel to the first center line (L 1 ), onto the image plane (I p ) is expected to reproduce the first ellipse (E 1 ), and determining a first eye intersecting line (D 1 ) expected to intersect a center (M) of the eyeball (H 1 ) at the first time (t 1 ) as a line which is, in the direction of the orientation vector (η 1 ), parallel-shifted to the first center line (L 1 ) by an expected distance (R) between the center (M) of the eyeball (H 1 ) and a center (P) of the pupil (H 3 )
