Abstract
A disclosed computer-implemented method may include directing an illumination source, positioned at a predetermined position relative to an event camera positioned to receive light from the illumination source reflected by a portion of a cornea of a user during an illumination sequence, to illuminate the portion of the cornea of the user in accordance with the illumination sequence. The method may also include detecting, via the event camera, a set of events, each event in the set of events comprising a change in an intensity of light from the illumination source received by a pixel included in the event camera over a sampling period of the event camera. The method may further include determining a shape of the portion of the cornea of the user based on the predetermined position, the illumination sequence, and the set of events. Various other apparatuses, systems, methods, and computer-readable media are also disclosed.
