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： Methods, devices and systems for generating data suitable for determining at least one eye state variable of at least one eye of a subject, and methods and systems for determining such eye state variables are provided. The eye comprises an eyeball, an iris defining a pupil, and a cornea, the at least one eye state variable being derivable from at least one image of the eye taken with a camera of known camera intrinsics. In a simulation scenario, synthetic image data of a first 3D model eye which models corneal refraction can be generated for different sets of eye state variables and a given algorithm may be used to determine said eye state variables using a further 3D eye model comprising at least one parameter, in particular this model can be simpler and does not need to explicitly model corneal refraction. A characteristic of the pupil image in the synthetic images can be determined and relationships can be established between hypothetically optimal values of the at least one model parameter and the characteristic, for later use by a given algorithm to determine eye state variables based on image data of real eyes and under use of the further 3D eye model, while taking into account effects of corneal refraction of the real eyes via the characteristic-dependent eye model parameter.
